 ## Project Overview
 
-samsa is a privacy-respecting metasearch engine written in Go. It provides a SearXNG-compatible `/search` API and an HTML frontend (HTMX + Go templates). 9 engines are implemented natively in Go; unlisted engines can be proxied to an upstream metasearch instance. Responses from multiple engines are merged into a single JSON/CSV/RSS/HTML response.

-# Contributing — Adding a New Engine
-
-This guide walks through adding a new search engine to samsa. The minimal engine needs only an HTTP client, a query, and a result parser.
-
----
-
-## 1. Create the engine file
-
-Place it in `internal/engines/`:
-
-```
-internal/engines/
-  myengine.go        ← your engine
-  myengine_test.go   ← tests (required)
-```
-
-Name the struct after the engine, e.g. `WolframEngine` for "wolfram". The `Name()` method returns the engine key used throughout samsa.
-
-## 2. Implement the Engine interface
-
-```go
-package engines
-
-import (
-    "context"
-    "github.com/metamorphosis-dev/samsa/internal/contracts"
-)
-
-type MyEngine struct {
-    client *http.Client
-}
-
-func (e *MyEngine) Name() string { return "myengine" }
-
-func (e *MyEngine) Search(ctx context.Context, req contracts.SearchRequest) (contracts.SearchResponse, error) {
-    // ...
-}
-```
-
-### The SearchRequest fields you'll use most:
-
-| Field | Type | Description |
-|-------|------|-------------|
-| `Query` | `string` | The search query |
-| `Pageno` | `int` | Current page number (1-based) |
-| `Safesearch` | `int` | 0=off, 1=moderate, 2=strict |
-| `Language` | `string` | ISO language code (e.g. `"en"`) |
-
-### The SearchResponse to return:
-
-```go
-contracts.SearchResponse{
-    Query:               req.Query,
-    NumberOfResults:     len(results),
-    Results:             results,       // []MainResult
-    Answers:             []map[string]any{},
-    Corrections:         []string{},
-    Infoboxes:           []map[string]any{},
-    Suggestions:         []string{},
-    UnresponsiveEngines: [][2]string{},
-}
-```
-
-### Empty query — return early:
-
-```go
-if strings.TrimSpace(req.Query) == "" {
-    return contracts.SearchResponse{Query: req.Query}, nil
-}
-```
-
-### Engine unavailable / error — graceful degradation:
-
-```go
-// Rate limited or blocked
-return contracts.SearchResponse{
-    Query:               req.Query,
-    UnresponsiveEngines: [][2]string{{"myengine", "reason"}},
-    Results:             []contracts.MainResult{},
-    // ... empty other fields
-}, nil
-
-// Hard error — return it
-return contracts.SearchResponse{}, fmt.Errorf("myengine upstream error: status %d", resp.StatusCode)
-```
-
-## 3. Build the result
-
-```go
-urlPtr := "https://example.com/result"
-result := contracts.MainResult{
-    Title:    "Result Title",
-    Content:  "Snippet or description text",
-    URL:      &urlPtr,       // pointer to string, required
-    Engine:   "myengine",
-    Category: "general",     // or "it", "science", "videos", "images", "social media"
-    Score:    0,             // used for relevance ranking during merge
-    Engines:  []string{"myengine"},
-}
-```
-
-### Template field
-
-The template system checks for `"videos"` and `"images"`. Everything else renders via `result_item.html`. Set `Template` only if you have a custom template; omit it for the default result card.
-
-### Category field
-
-Controls which category tab the result appears under and which engines are triggered:
-
-| Category | Engines used |
-|----------|-------------|
-| `general` | google, bing, ddg, brave, braveapi, qwant, wikipedia |
-| `it` | github, stackoverflow |
-| `science` | arxiv, crossref |
-| `videos` | youtube |
-| `images` | bing_images, ddg_images, qwant_images |
-| `social media` | reddit |
-
-## 4. Wire it into the factory
-
-In `internal/engines/factory.go`, add your engine to the map returned by `NewDefaultPortedEngines`:
-
-```go
-"myengine": &MyEngine{client: client},
-```
-
-If your engine needs an API key, read it from config or the environment (see `braveapi` or `youtube` in factory.go for the pattern).
-
-## 5. Register defaults
-
-In `internal/engines/planner.go`:
-
-**Add to `defaultPortedEngines`:**
-```go
-var defaultPortedEngines = []string{
-    // ... existing ...
-    "myengine",
-}
-```
-
-**Add to category mapping in `inferFromCategories`** (if applicable):
-```go
-case "general":
-    set["myengine"] = true
-```
-
-**Update the sort order map** so results maintain consistent ordering:
-```go
-order := map[string]int{
-    // ... existing ...
-    "myengine": N,  // pick a slot
-}
-```
-
-## 6. Add tests
-
-At minimum, test:
-- `Name()` returns the correct string
-- Nil engine returns an error
-- Empty query returns zero results
-- Successful API response parses correctly
-- Rate limit / error cases return `UnresponsiveEngines` with a reason
-
-Use `httptest.NewServer` to mock the upstream API. See `arxiv_test.go` or `reddit_test.go` for examples.
-
-## 7. Build and test
-
-```bash
-go build ./...
-go test ./internal/engines/ -run MyEngine -v
-go test ./...
-```
-
-## Example: Adding an RSS-based engine
-
-If the engine provides an RSS feed, the parsing is straightforward:
-
-```go
-type rssItem struct {

+# Brave Search Frontend Redesign — Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** Redesign the kafka frontend to match Brave Search's layout: three-column results page, category tiles on homepage, and a hybrid preferences system with full-page `/preferences` route.
+
+**Architecture:** CSS Grid for page-level layouts (three-column results, two-column preferences). JavaScript popover for quick settings (theme + engines only). Server-rendered full preferences page with localStorage persistence. Category tiles are static links with category query params.
+
+**Tech Stack:** Go (Go templates), CSS Grid/Flexbox, Vanilla JavaScript (HTMX for search), localStorage for preferences
+
+---
+
+## File Map
+
+| File | Responsibility |
+|------|----------------|
+| `internal/views/static/css/kafka.css` | Add layout grids, category tiles, sidebar styles, mobile breakpoints |
+| `internal/views/templates/index.html` | Add category tiles below search box |
+| `internal/views/templates/results.html` | Add left sidebar, restructure for three-column grid |
+| `internal/views/templates/preferences.html` | **New** — full preferences page with nav |
+| `internal/views/templates/base.html` | No structural changes needed |
+| `internal/views/static/js/settings.js` | Reduce popover to theme + engines; add preferences page JS |
+| `internal/httpapi/handlers.go` | Add `GET /preferences` and `POST /preferences` handlers |
+| `internal/views/views.go` | Add `RenderPreferences` and `tmplPreferences` template |
+

+- [ ] **Step 6: Verify Go compilation**
+
+Run: `go build ./...`
+Expected: No errors
+
+Note: CSS is embedded as static files and not processed by the Go compiler. CSS changes must be tested manually in a browser.
+
+- [ ] **Step 7: Commit**
+
+```bash
+git add internal/views/static/css/kafka.css
+git commit -m "feat(frontend): add CSS layout framework for three-column results and preferences page"
+```
+
+---
+
+## PHASE 2: Results Page Three-Column Layout
+
+### Task 2: Restructure Results Template
+
+**Files:**
+- Modify: `internal/views/templates/results.html`
+- Modify: `internal/views/views.go`
+
+- [ ] **Step 1: Read current results.html to understand exact content**
+
+Current structure has `.results-layout` grid with `.search-compact` spanning full width, `.results-column`, and `.sidebar`. Need to add left sidebar and restructure grid.
+
+- [ ] **Step 2: Replace results.html content**
+
+Replace the entire file content:
+
+```html
+{{define "title"}}{{if .Query}}{{.Query}} — {{end}}{{end}}
+{{define "content"}}
+<div class="results-layout">
+  <!-- Left Sidebar -->
+  <aside class="left-sidebar" id="left-sidebar">

+        {{end}}
+      </div>
+    </div>
+  </aside>
+
+  <!-- Center Column -->
+  <div class="results-column">
+    <!-- Compact search bar -->
+    <div class="search-compact">
+      <div class="search-box">

+      </ul>
+    </div>
+    {{end}}
+  </aside>
+</div>
+{{end}}
+```
+
+- [ ] **Step 3: Add FilterOption struct and update PageData struct**
+
+Add `FilterOption` struct at package level in `views.go` (near `PageNumber` struct):
+
+```go
+// FilterOption represents a filter radio option for the sidebar.
+type FilterOption struct {
+    Label string
+    Value string
+}
+```
+
+Then update `PageData` struct to include new fields:
+
+```go
+type PageData struct {
+    // ... existing fields (SourceURL, Query, Pageno, etc.) ...
+
+    // New fields for three-column layout
+    Categories         []string
+    CategoryIcons     map[string]string
+    DisabledCategories []string
+    ActiveCategory    string
+    TimeFilters       []FilterOption
+    TypeFilters       []FilterOption
+    ActiveTime        string
+    ActiveType        string
+}
+```
+
+- [ ] **Step 4: Update FromResponse signature and body**
+
+Update `FromResponse` signature to accept filter params and set defaults:
+
+```go
+func FromResponse(resp contracts.SearchResponse, query string, pageno int, activeCategory, activeTime, activeType string) PageData {
+    // Set defaults
+    if activeCategory == "" {
+        activeCategory = "all"
+    }
+
+    pd := PageData{
+        // ... existing initialization (NumberOfResults, Results, etc.) ...
+
+        // New: categories with icons
+        Categories: []string{"all", "news", "images", "videos", "maps"},
+        DisabledCategories: []string{"shopping", "music", "weather"},
+        CategoryIcons: map[string]string{
+            "all":      "🌐",
+            "news":     "📰",
+            "images":   "🖼️",
+            "videos":   "🎬",
+            "maps":     "🗺️",
+            "shopping": "🛒",
+            "music":    "🎵",
+            "weather":  "🌤️",
+        },
+        ActiveCategory: activeCategory,
+
+        // Time filters
+        TimeFilters: []FilterOption{
+            {Label: "Any time", Value: ""},
+            {Label: "Past hour", Value: "h"},
+            {Label: "Past 24 hours", Value: "d"},
+            {Label: "Past week", Value: "w"},
+            {Label: "Past month", Value: "m"},
+            {Label: "Past year", Value: "y"},
+        },
+        ActiveTime: activeTime,
+
+        // Type filters
+        TypeFilters: []FilterOption{
+            {Label: "All results", Value: ""},
+            {Label: "News", Value: "news"},
+            {Label: "Videos", Value: "video"},
+            {Label: "Images", Value: "image"},
+        },
+        ActiveType: activeType,
+    }
+    // ... rest of function ...
+}
+```
+
+Update the `Search` handler in `handlers.go` to pass filter params:
+
+```go
+pd := views.FromResponse(resp, req.Query, req.Pageno,
+    r.FormValue("category"), r.FormValue("time"), r.FormValue("type"))
+```
+
+- [ ] **Step 5: Update results.html sidebar to show disabled state**
+
+Update the sidebar category loop to conditionally apply `disabled` class:
+
+```html
+{{range .Categories}}
+<a href="/search?q={{$.Query | urlquery}}&category={{.}}" class="sidebar-nav-item {{if eq $.ActiveCategory .}}active{{end}}">
+  <span class="sidebar-nav-item-icon">{{index $.CategoryIcons .}}</span>
+  <span>{{.}}</span>
+</a>
+{{end}}
+<!-- Disabled categories with no links -->
+{{range .DisabledCategories}}
+<span class="sidebar-nav-item disabled">
+  <span class="sidebar-nav-item-icon">{{index $.CategoryIcons .}}</span>
+  <span>{{.}}</span>
+</span>
+{{end}}
+```
+
+- [ ] **Step 6: Test compilation**
+
+Run: `go build ./...`
+Expected: No errors
+
+- [ ] **Step 7: Commit**
+
+```bash
+git add internal/views/views.go internal/views/templates/results.html
+git commit -m "feat(frontend): add three-column results layout with left sidebar navigation"
+```

+- [ ] **Step 2: Add preferences section CSS styles**
+
+Append to `kafka.css`:
+
+```css
+/* ============================================================
+   Preferences Page Styles
+   ============================================================ */
+
+.pref-section {
+  margin-bottom: 2rem;

+  flex-shrink: 0;
+}
+
+.pref-row input[type="checkbox"]:disabled {
+  opacity: 0.6;
+  cursor: not-allowed;
+}
+```
+
+- [ ] **Step 3: Register preferences template in views.go**
+
+Add `tmplPreferences` variable and initialize it in `init()`. Also add `RenderPreferences` function:
+
+```go
+// In views.go, add to var block:
+var (
+    tmplFull        *template.Template
+    tmplIndex       *template.Template
+    tmplFragment    *template.Template
+    tmplPreferences *template.Template
+)
+
+// In init(), after existing template parsing, add:
+tmplPreferences = template.Must(template.New("").Funcs(funcMap).ParseFS(tmplFS,
+    "base.html", "preferences.html",
+))
+
+// Add RenderPreferences function:
+func RenderPreferences(w http.ResponseWriter, sourceURL string) error {
+    w.Header().Set("Content-Type", "text/html; charset=utf-8")
+    return tmplPreferences.ExecuteTemplate(w, "base", PageData{ShowHeader: true, SourceURL: sourceURL})
+}
+```
+
+- [ ] **Step 4: Commit**
+
+```bash
+git add internal/views/templates/preferences.html internal/views/static/css/kafka.css internal/views/views.go
+git commit -m "feat(frontend): add preferences page template and styles"
+```
+
+---
+
+### Task 5: Add Preferences Route
+
+**Files:**
+- Modify: `internal/httpapi/handlers.go`
+- Modify: `cmd/kafka/main.go`
+
+- [ ] **Step 1: Add GET and POST handlers for /preferences**
+
+Add to `handlers.go`:
+
+```go
+// Preferences renders the preferences page.
+func (h *Handler) Preferences(w http.ResponseWriter, r *http.Request) {
+    if r.URL.Path != "/preferences" {
+        http.NotFound(w, r)
+        return
+    }
+    if err := views.RenderPreferences(w, h.sourceURL); err != nil {
+        http.Error(w, err.Error(), http.StatusInternalServerError)
+    }
+}
+
+// PreferencesPOST handles form submission from the preferences page.
+// NOTE: This is a no-op. All preferences are stored in localStorage on the client
+// via JavaScript. This handler exists only for form submission completeness (e.g.,
+// if a form POSTs without JS). The JavaScript in settings.js handles all saves.
+func (h *Handler) PreferencesPOST(w http.ResponseWriter, r *http.Request) {
+    if r.URL.Path != "/preferences" {
+        http.NotFound(w, r)
+        return
+    }
+    http.Redirect(w, r, "/preferences", http.StatusFound)
+}
+```
+
+- [ ] **Step 2: Register the route in main**
+
+Find where routes are registered (likely in `cmd/kafka/main.go`) and add:
+
+```go
+mux.HandleFunc("GET /preferences", handler.Preferences)
+mux.HandleFunc("POST /preferences", handler.PreferencesPOST)
+```
+
+- [ ] **Step 3: Test compilation**
+
+Run: `go build ./...`
+Expected: No errors
+
+- [ ] **Step 4: Commit**
+
+```bash
+git add internal/httpapi/handlers.go cmd/kafka/main.go
+git commit -m "feat: add GET and POST /preferences route"
+```
+
+---
+
+### Task 6: Update Settings JavaScript
+
+**Files:**
+- Modify: `internal/views/static/js/settings.js`
+
+- [ ] **Step 1: Reduce popover to theme + engines only**
+
+Update the `renderPanel` function to remove SafeSearch and Format options. Keep only theme buttons and engine toggles.
+
+- [ ] **Step 2: Add preferences page navigation JavaScript**
+
+Add to end of `settings.js`:
+
+```javascript
+// Preferences page navigation
+function initPreferences() {
+  var nav = document.getElementById('preferences-nav');
+  if (!nav) return;
+
+  var sections = document.querySelectorAll('.pref-section');
+  var navItems = nav.querySelectorAll('.preferences-nav-item');
+
+  function showSection(id) {
+    sections.forEach(function(sec) {
+      sec.style.display = sec.id === 'section-' + id ? 'block' : 'none';
+    });
+    navItems.forEach(function(item) {
+      item.classList.toggle('active', item.getAttribute('data-section') === id);
+    });
+  }
+
+  navItems.forEach(function(item) {
+    item.addEventListener('click', function() {
+      showSection(item.getAttribute('data-section'));
+    });
+  });
+
+  // Load saved preferences
+  var prefs = loadPrefs();
+  var themeEl = document.getElementById('pref-theme');
+  if (themeEl) themeEl.value = prefs.theme || 'system';
+
+  var ssEl = document.getElementById('pref-safesearch');
+  if (ssEl) ssEl.value = prefs.safeSearch || 'moderate';
+
+  var fmtEl = document.getElementById('pref-format');
+  if (fmtEl) fmtEl.value = prefs.format || 'html';
+
+  // Save handlers
+  if (themeEl) {
+    themeEl.addEventListener('change', function() {
+      prefs.theme = themeEl.value;
+      savePrefs(prefs);
+      applyTheme(prefs.theme);
+    });
+  }
+
+  if (ssEl) {
+    ssEl.addEventListener('change', function() {
+      prefs.safeSearch = ssEl.value;
+      savePrefs(prefs);
+    });
+  }
+
+  if (fmtEl) {
+    fmtEl.addEventListener('change', function() {
+      prefs.format = fmtEl.value;
+      savePrefs(prefs);
+    });
+  }
+
+  // Show first section by default
+  showSection('search');
+}
+
+document.addEventListener('DOMContentLoaded', initPreferences);
+```
+
+- [ ] **Step 3: Test with browser**
+
+Manual verification needed — cannot test browser JS with `go build`
+
+- [ ] **Step 4: Commit**
+
+```bash
+git add internal/views/static/js/settings.js
+git commit -m "feat(frontend): reduce popover to theme+engines, add preferences page JS"
+```

+
+## PHASE 5: Polish and Mobile Responsiveness
+
+### Task 7: Mobile Filter Chips Integration
+
+**Files:**
+- Modify: `internal/views/templates/results.html`
+
+- [ ] **Step 1: Ensure mobile filter chips have working category links**
+
+The current results.html has mobile filter chips with category links. These should preserve existing query params for pagination/HTMX navigation.
+
+- [ ] **Step 2: Add filter form submission via HTMX**
+
+Update the filter radio buttons to submit via HTMX when changed.
+
+- [ ] **Step 3: Commit**
+
+```bash
+git add internal/views/templates/results.html
+git commit -m "fix(frontend): add HTMX filter submission"
+```
+
+---
+
+### Task 8: Final Mobile Responsiveness Audit
+
+**Files:**
+- Review: `internal/views/static/css/kafka.css`
+
+- [ ] **Step 1: Test all breakpoints manually**
+
+- [ ] **Step 2: Fix any layout issues found**
+
+- [ ] **Step 3: Commit any fixes**
+
+```bash
+git add internal/views/static/css/kafka.css

+# Settings UI Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** A preferences popover panel (top-right on desktop, bottom sheet on mobile) that lets users set theme, enabled engines, safe search, and default format. All changes auto-save to `localStorage` and apply immediately to the DOM.
+
+**Architecture:** Pure client-side JS + CSS added alongside existing templates. No Go changes. Settings persist via `localStorage` key `kafka_prefs`. Theme applies via `data-theme` attribute on `<html>`.
+
+**Tech Stack:** Vanilla JS (no framework), existing `kafka.css` custom properties, HTMX for search.

+## File Map
+
+| Action | File |
+|--------|------|
+| Create | `internal/views/static/js/settings.js` |
+| Modify | `internal/views/static/css/kafka.css` |
+| Modify | `internal/views/templates/base.html` |
+| Modify | `internal/views/templates/index.html` |
+| Modify | `internal/views/templates/results.html` |
+| Modify | `internal/views/views.go` |
+
+**Key insight on engine preferences:** `ParseSearchRequest` reads `engines` as a CSV form value (`r.FormValue("engines")`). The search forms in `index.html` and `results.html` will get a hidden `#engines-input` field that is kept in sync with localStorage. On submit, the engines preference is sent as a normal form field. HTMX `hx-include="this"` already includes the form element, so the hidden input is automatically included in the request.

+<input type="hidden" name="engines" id="engines-input" value="">
+```
+
+The `value` is populated by `syncEngineInput(prefs)` on page load. When the form submits (regular GET or HTMX), the `engines` parameter is included as a CSV string, which `ParseSearchRequest` reads correctly via `r.FormValue("engines")`.
+
+- [ ] **Step 2: Verify existing search works**
+
+Run: `go run ./cmd/kafka -config config.toml`
+Open: `http://localhost:8080`
+Search for "golang" — results should appear as normal.
+
+- [ ] **Step 3: Commit**
+
+```bash
+git add internal/views/templates/index.html internal/views/templates/results.html
+git commit -m "feat(settings): add hidden engines input to search forms"
+```
+
+---
+
+## Task 5: End-to-end verification
+
+- [ ] **Step 1: Start server**
+
+Run: `go run ./cmd/kafka -config config.toml`
+Open: `http://localhost:8080`
+
+- [ ] **Step 2: Verify gear icon and panel**
+
+Click the gear icon in the header — panel drops down from top-right with Appearance, Engines, and Search Defaults sections.
+
+- [ ] **Step 3: Verify theme persistence**
+
+Click Dark → page colors change immediately. Refresh → dark theme persists.
+
+- [ ] **Step 4: Verify engine toggle persistence**
+
+Uncheck "wikipedia", refresh → "wikipedia" stays unchecked.
+
+- [ ] **Step 5: Verify engines appear in search query**
+
+With wikipedia unchecked, open DevTools → Network tab, search "golang". Verify request URL includes `&engines=arxiv,crossref,...` (no wikipedia).
+
+- [ ] **Step 6: Verify mobile bottom sheet**
+
+Resize to <768px or use mobile device emulation. Click gear → full-width sheet slides up from bottom.
+
+- [ ] **Step 7: Final commit**
+
+```bash
+git add -A
+git commit -m "feat: complete settings UI — popover, auto-save, theme, engines, mobile bottom-sheet"
+```

-# Per-Engine TTL Cache — Implementation Plan
-
-> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
-
-**Goal:** Replace the merged-response cache with per-engine response caching, enabling tier-based TTLs and stale-while-revalidate semantics.
-
-**Architecture:** Each engine's raw response is cached independently with its tier-based TTL. On stale hits, return cached data immediately and refresh in background. Query hash is computed from shared params (query, pageno, safesearch, language, time_range) and prefixed with engine name for the cache key.
-
-**Tech Stack:** Go 1.24, Valkey/Redis (go-redis/v9), existing samsa contracts

-## Task 5: Wire EngineCache into search service
-
-**Files:**
-- Modify: `internal/search/service.go`
-
-- [ ] **Step 1: Read the current service.go to understand wiring**
-
-The service currently takes `*Cache` in `ServiceConfig`. We need to change it to take `*EngineCache` or change the field type.
-
-- [ ] **Step 2: Modify Service struct and NewService to use EngineCache**
-
-Change `Service`:
-
-```go
-type Service struct {
-    upstreamClient *upstream.Client
-    planner        *engines.Planner
-    localEngines   map[string]engines.Engine
-    engineCache    *cache.EngineCache
-}
-```
-
-Change `NewService`:
-
-```go
-func NewService(cfg ServiceConfig) *Service {
-    timeout := cfg.HTTPTimeout
-    if timeout <= 0 {
-        timeout = 10 * time.Second
-    }
-
-    httpClient := httpclient.NewClient(timeout)

-
-    var engineCache *cache.EngineCache
-    if cfg.Cache != nil {
-        engineCache = cache.NewEngineCache(cfg.Cache, cfg.CacheTTLOverrides)
-    }
-
-    return &Service{
-        upstreamClient: up,
-        planner:        engines.NewPlannerFromEnv(),
-        localEngines:   engines.NewDefaultPortedEngines(httpClient, cfg.EnginesConfig),
-        engineCache:    engineCache,
-    }
-}
-```
-
-Add `CacheTTLOverrides` to `ServiceConfig`:
-
-```go
-type ServiceConfig struct {
-    UpstreamURL       string
-    HTTPTimeout       time.Duration
-    Cache             *cache.Cache
-    CacheTTLOverrides map[string]time.Duration

-The stale-while-revalidate flow:
-
-1. **Cache lookup (Phase 1)**: Check cache for each engine in parallel. Classify each as:
-   - Fresh hit: cache has data AND not stale → deserialize, mark as `fresh`
-   - Stale hit: cache has data AND stale → keep in `cached`, no `fresh` yet
-   - Miss: cache has no data → `hit=false`, no `cached` or `fresh`
-
-2. **Fetch (Phase 2)**: For each engine:
-   - Fresh hit: return immediately, no fetch needed
-   - Stale hit: return stale data immediately, fetch fresh in background
-   - Miss: fetch fresh synchronously, cache result
-
-3. **Collect (Phase 3)**: Collect all responses for merge.
-
-```go
-// Search executes the request against local engines (in parallel) and
-// optionally the upstream instance for unported engines.
-func (s *Service) Search(ctx context.Context, req SearchRequest) (SearchResponse, error) {
-    queryHash := cache.QueryHash(
-        req.Query,
-        int(req.Pageno),

-    )
-
-    localEngineNames, upstreamEngineNames, _ := s.planner.Plan(req)
-
-    // Phase 1: Parallel cache lookups — classify each engine as fresh/stale/miss
-    type cacheResult struct {
-        engine       string

-        hit          bool
-        fresh        contracts.SearchResponse
-        fetchErr     error

-
-Note: The imports need `encoding/json` and `fmt` added. The existing imports in service.go already include `sync` and `time`.
-
-- [ ] **Step 4: Run tests to verify compilation**
-
-Run: `nix develop --command bash -c "go build ./internal/search/"`
-Expected: no output (success)
-
-- [ ] **Step 5: Run full test suite**
-
-Run: `nix develop --command bash -c "go test ./..."`
-Expected: All pass
-
-- [ ] **Step 6: Commit**
-
-```bash
-git add internal/search/service.go
-git commit -m "search: wire per-engine cache with tier-aware TTLs"
-```
-
----
-
-## Task 6: Update config.example.toml
-
-**Files:**
-- Modify: `config.example.toml`
-
-- [ ] **Step 1: Add TTL overrides section to config.example.toml**
-
-Add after the `[cache]` section:
-
-```toml
-[cache.ttl_overrides]
-# Per-engine TTL overrides (uncomment to use):
-# wikipedia = "48h"
-# reddit = "15m"
-# braveapi = "2h"
-```
-
-- [ ] **Step 2: Commit**
-
-```bash
-git add config.example.toml
-git commit -m "config: add cache.ttl_overrides example"
-```
-
----
-
-## Verification
-
-After all tasks complete, run:
-
-```bash
-nix develop --command bash -c "go test ./... -v 2>&1 | tail -50"
-```
-
-All tests should pass. The search service should now cache each engine's response independently with tier-based TTLs.

+# Brave Search Frontend Redesign — Design Specification
+
+## Overview
+
+Redesign the kafka frontend to match Brave Search's clean, functional aesthetic with emphasis on layout changes: three-column results page, category tiles on homepage, and a hybrid preferences system with full-page `/preferences` route.
+
+## Design Principles
+
+1. **Brave-like layout** — Three-column results, full-page preferences, homepage tiles
+2. **Preserve existing design tokens** — Keep current CSS variables (colors, spacing, radii)
+3. **CSS Grid for layout** — Three-column grid for results, flexible layouts elsewhere
+4. **Hybrid preferences** — Quick popover for common settings (theme + engines), full `/preferences` page for all options
+5. **Minimal HTML changes** — Restructure templates where needed for layout, reuse existing partials
+6. **localStorage-only preferences** — No server-side persistence; all preferences stored in browser localStorage
+
+---
+
+## 1. Homepage Redesign
+
+### Current State
+- Centered hero with logo, tagline, and search box
+- No visual categorization of search types
+
+### New Layout
+```

+└─────────────────────────────────────────────────────────────┘
+```
+
+### Implementation
+- **File:** `internal/views/templates/index.html`
+- **Structure:** Search hero + category tiles grid
+- **Tiles:** Static links to `/search?q=...` with category parameter (e.g., `&category=images`)
+- **Styling:** Grid of icon+label cards below search box, subtle hover effects
+
+### Category Tiles
+| Category | Icon | Notes |
+|----------|------|-------|
+| All | 🌐 | Default, no category param |
+| News | 📰 | |
+| Images | 🖼️ | |
+| Videos | 🎬 | |
+| Maps | 🗺️ | |
+| Shopping | 🛒 | Future: connect to shopping engine |
+| Music | 🎵 | Future: connect to music engine |
+| Weather | 🌤️ | Future: connect to weather API |
+| Sports | ⚽ | Future |
+| Cryptocurrency | ₿ | Future |
+
+Categories marked "Future" are included in the UI but may not have backend support yet. Category tiles that lack backend support display grayed out with a "Coming soon" tooltip.

+
+## 2. Results Page — Three-Column Layout
+
+### Current State
+- Two columns: compact search bar spanning top, main results + right sidebar
+
+### New Layout

+└─────────────────────────────────────────────────────────────┘
+```
+
+### Implementation
+- **Files:** `internal/views/templates/results.html`, `internal/views/templates/base.html`
+- **Left Sidebar (desktop, sticky):**
+  - Category navigation links (All, Images, Videos, News, Maps, Shopping, Music, Weather)
+  - Filters section (Time range, Result type) — collapsible
+  - Hidden on mobile (< 768px)
+
+- **Center Column:**
+  - Compact search bar
+  - Results count meta: "About {n} results ({time}s)"
+  - Result cards (unchanged markup)
+  - Pagination
+
+- **Right Sidebar:**
+  - Related searches (existing suggestions)
+  - Additional panels as needed
+
+### Filters
+**Time Range Options:**
+| Label | Query Param |
+|-------|-------------|
+| Any time | (none) |
+| Past hour | `&time=h` |
+| Past 24 hours | `&time=d` |
+| Past week | `&time=w` |
+| Past month | `&time=m` |
+| Past year | `&time=y` |
+
+**Result Type Options:**
+| Label | Query Param |
+|-------|-------------|
+| All results | (none) |
+| News | `&type=news` |
+| Videos | `&type=video` |
+| Images | `&type=image` |
+
+Filter state persists in URL query params and is preserved across HTMX navigation via `hx-include`.
+
+### Mobile Behavior
+| Breakpoint | Layout |
+|------------|--------|
+| < 768px | Single column, no left sidebar |
+| 768px - 1024px | Two columns (center + right sidebar), no left nav |
+| > 1024px | Full three columns |
+
+On mobile (< 768px):
+- Category filters accessible via a horizontal scrollable chip row above results
+- Both sidebars hidden
+- Search bar full-width
+
+---
+
+## 3. Preferences Page — Full-Page Hybrid
+
+### Current State
+- Popover triggered by gear icon in header
+- JavaScript-rendered from localStorage
+- Sections: Appearance, Engines, Search Defaults
+
+### New Layout

+│  └────────────────┘  └─────────────────────────────────────┘│
+└─────────────────────────────────────────────────────────────┘
+```
+
+### Sections (Brave-style)
+1. **Search** — Default engine, safe search, language
+2. **Privacy** — Tracking protection toggle (UI only, always on), request DNT header toggle
+3. **Tabs** — New tab behavior (placeholder section)
+4. **Appearance** — Theme (Light/Dark/System), results font size
+5. **Sidebar** — Sidebar visibility toggle
+6. **Content** — Filter explicit results (SafeSearch), auto-play media toggle
+7. **Languages** — UI language (English only for now), search language
+8. **Regional** — Region/Country, timezone (placeholder)
+
+### Implementation
+- **Route:** Add `GET /preferences` and `POST /preferences` to `internal/httpapi/`
+- **Template:** `internal/views/templates/preferences.html`
+- **Storage:** localStorage-only. GET handler renders page shell, JavaScript populates form values from localStorage. POST handler receives form data, writes to localStorage, re-renders page.
+- **Quick Settings Popover:** Keep existing popover for **theme toggle and engine toggles only** (lightweight, localStorage). SafeSearch and Format settings move exclusively to full preferences page.
+- **Styling:** Match existing design tokens, section headers, form controls
+
+### Preferences Nav (Mobile)
+- Horizontal scrollable nav on mobile (< 768px)
+- Active section highlighted
+
+---
+
+## 4. Component Changes
+
+### Header
+- Logo + site name (unchanged)
+- Preferences button (unchanged)
+
+### Search Box
+- Homepage: Larger, prominent, centered
+- Results page: Compact, full-width within center column
+
+### Result Cards
+- Keep existing structure
+- Consider subtle styling improvements (spacing, typography)
+
+### Category Tiles (Homepage)
+- Icon + label per category
+- Hover: slight scale + shadow
+
+### Left Sidebar (Results Page)
+- Sticky positioning (`position: sticky; top: calc(var(--header-height) + 1rem)`)
+- Category links with active state indicator
+- Collapsible filter sections
+
+### Preferences Nav
+- Vertical nav with section icons
+- Active state indicator
+- Mobile: horizontal scroll
+
+---
+
+## 5. CSS Architecture
+
+### Existing (Retain)
+- CSS custom properties (design tokens)
+- Component-level styles
+- Dark mode via `[data-theme="dark"]`
+
+### New
+
+**Layout Grid for three-column results:**
+```css
+.results-layout {
+  display: grid;
+  grid-template-columns: 200px 1fr 240px;
+  gap: 2rem;
+  align-items: start;
+}
+```
+
+**Sticky Left Sidebar:**
+```css
+.results-layout .left-sidebar {
+  position: sticky;
+  top: calc(var(--header-height) + 1.5rem);
+  max-height: calc(100vh - var(--header-height) - 3rem);
+  overflow-y: auto;
+}
+```
+
+**Preferences page layout:**
+```css
+.preferences-layout {
+  display: grid;
+  grid-template-columns: 200px 1fr;
+  gap: 2rem;

+```
+
+**Category tiles grid:**
+```css
+.category-tiles {
+  display: grid;
+  grid-template-columns: repeat(auto-fill, minmax(100px, 1fr));
+  gap: 1rem;
+}
+```
+
+**Mobile breakpoints:**
+```css
+@media (max-width: 768px) {
+  .results-layout {
+    grid-template-columns: 1fr;
+  }
+  .results-layout .left-sidebar,
+  .results-layout .right-sidebar {

+# Settings UI Design — kafka
+
+**Date:** 2026-03-22
+**Status:** Approved
+
+## Overview
+
+A lightweight preferences popover anchored to the top-right, just below the header. Triggered by a gear icon, it lets users adjust theme, enabled engines, and search defaults without leaving their current page. All changes auto-save to `localStorage` on every interaction.
+
+## Layout & Structure
+
+- **Trigger**: Gear icon (⚙️) in the top-right header, aligned with the header's right edge
+- **Panel**: 280px wide, max-height 420px, scrollable internally, rounded corners, subtle shadow, anchored top-right (drops down from trigger, like a dropdown)
+- **Close**: × button in panel header, click outside the panel, or pressing Escape
+- **No Save button** — every interaction immediately writes to `localStorage`
+
+## Interaction Flow
+
+1. User clicks ⚙️ → panel drops down from top-right (200ms ease)
+2. User toggles/clicks → changes apply instantly to DOM + write to `localStorage`
+3. User clicks × or outside or Escape → panel closes, settings persist
+4. **Accessibility**: Focus is trapped within the panel while open. Trigger button uses `aria-expanded` and `aria-controls`. Escape key closes the panel.
+
+## Mid-Search Changes
+
+When opened during an active search on `results.html`:
+- Engine toggles update `localStorage` immediately, but **current results remain unchanged**
+- A subtle inline note below the engines section: *"Engine changes apply to your next search"*
+
+## Sections
+
+### Appearance
+
+- Three theme buttons: ☀️ Light / 🌙 Dark / 💻 System
+- Clicking immediately applies via `document.body.classList` + writes to localStorage
+- "System" reads `prefers-color-scheme` and updates on change
+
+### Engines
+
+- 2-column grid of toggle switches for all 9 engines
+- Each row: engine name + toggle switch
+- Enabled = filled accent color; Disabled = gray outline
+
+### Search Defaults
+
+- Safe search: dropdown (Moderate / Strict / Off)
+- Default format: dropdown (HTML / JSON / CSV)
+
+## Default State
+
+```js
+const DEFAULT_PREFS = {
+  theme: "system",
+  engines: ["wikipedia", "arxiv", "crossref", "braveapi", "qwant", "duckduckgo", "github", "reddit", "bing"],
+  safeSearch: "moderate",
+  format: "html"
+};
+```
+
+## Persistence
+
+```js
+// Written on every interaction
+localStorage.setItem('kafka_prefs', JSON.stringify({ ... }));
+
+// Read on page load — merge with DEFAULT_PREFS
+const saved = JSON.parse(localStorage.getItem('kafka_prefs') || '{}');
+const prefs = { ...DEFAULT_PREFS, ...saved };
+```
+
+## Responsive Behavior
+
+- **Mobile (<768px)**: Panel becomes a **bottom sheet** — 100% width, slides up from the bottom, top corners rounded, max-height 70vh. Trigger moves to a fixed bottom-right FAB button.
+- Panel never covers the search input
+
+## Applied to Existing Code
+
+- `base.html` — add gear button in header, panel markup at end of `<body>`
+- `kafka.css` — popover styles, toggle switch styles, bottom sheet styles for mobile
+- `settings.js` — localStorage read/write, theme application, panel toggle, aria attributes, focus trap

-# Per-Engine TTL Cache — Design
-
-## Overview
-
-Replace the current merged-response cache with a per-engine response cache. Each engine's raw response is cached independently with a tier-based TTL, enabling stale-while-revalidate semantics and more granular freshness control.
-
-## Cache Key Structure
-
-```
-samsa:resp:{engine}:{query_hash}
-```
-
-Where `query_hash` = SHA-256 of shared request params (query, pageno, safesearch, language, time_range), truncated to 16 hex chars.
-
-Example:
-- `samsa:resp:wikipedia:a3f1b2c3d4e5f678`
-- `samsa:resp:duckduckgo:a3f1b2c3d4e5f678`
-
-The same query to Wikipedia and DuckDuckGo produce different cache keys, enabling independent TTLs per engine.
-
-## Query Hash
-
-Compute from shared request parameters:
-
-```go
-func QueryHash(query string, pageno int, safesearch int, language, timeRange string) string {
-    h := sha256.New()
-    fmt.Fprintf(h, "q=%s|", query)
-    fmt.Fprintf(h, "pageno=%d|", pageno)
-    fmt.Fprintf(h, "safesearch=%d|", safesearch)
-    fmt.Fprintf(h, "lang=%s|", language)
-    if timeRange != "" {
-        fmt.Fprintf(h, "tr=%s|", timeRange)
-    }
-    return hex.EncodeToString(h.Sum(nil))[:16]
-}
-```
-
-Note: `engines` is NOT included because each engine has its own cache key prefix.
-
-## Cached Data Format
-
-Each cache entry stores:
-
-```go
-type CachedEngineResponse struct {
-    Engine   string    // engine name
-    Response []byte    // JSON-marshaled contracts.SearchResponse
-    StoredAt time.Time // when cached (for staleness check)
-}
-```
-
-## TTL Tiers
-
-### Default Tier Assignments
-
-| Tier | Engines | Default TTL |
-|------|---------|-------------|
-| `static` | wikipedia, wikidata, arxiv, crossref, stackoverflow, github | 24h |
-| `api_general` | braveapi, youtube | 1h |
-| `scraped_general` | google, bing, duckduckgo, qwant, brave | 2h |
-| `news_social` | reddit | 30m |
-| `images` | bing_images, ddg_images, qwant_images | 1h |
-
-### TOML Override Format
-
-```toml
-[cache.ttl_overrides]
-wikipedia = "48h"    # override default 24h
-reddit = "15m"       # override default 30m
-```
-
-## Search Flow
-
-### 1. Parse Request
-Extract engine list from planner, compute shared `queryHash`.
-
-### 2. Parallel Cache Lookups
-For each engine, spawn a goroutine to check cache:
-
-```go
-type engineCacheResult struct {
-    engine  string
-    resp    contracts.SearchResponse
-    fromCache bool
-    err     error
-}
-
-// For each engine, concurrently:
-cached, hit := engineCache.Get(ctx, engine, queryHash)
-if hit && !isStale(cached) {
-    return cached.Response, nil // fresh cache hit
-}
-if hit && isStale(cached) {
-    go refreshInBackground(engine, queryHash) // stale-while-revalidate
-    return cached.Response, nil // return stale immediately
-}
-// cache miss
-fresh, err := engine.Search(ctx, req)
-engineCache.Set(ctx, engine, queryHash, fresh)
-return fresh, err
-```
-
-### 3. Classify Each Engine
-- **Cache miss** → fetch fresh immediately
-- **Cache hit, fresh** → use cached
-- **Cache hit, stale** → use cached, fetch fresh in background (stale-while-revalidate)
-
-### 4. Background Refresh
-When a stale cache hit occurs:
-1. Return stale data immediately
-2. Spawn goroutine to fetch fresh data
-3. On success, overwrite cache with fresh data
-4. On failure, log and discard (stale data already returned)
-
-### 5. Merge
-Collect all engine responses (cached + fresh), merge via existing `MergeResponses`.
-
-### 6. Write Fresh to Cache
-For engines that were fetched fresh, write to cache with their tier TTL.
-
-## Staleness Check
-
-```go
-func isStale(cached CachedEngineResponse, tier TTLTier) bool {
-    return time.Since(cached.StoredAt) > tier.Duration
-}
-```
-
-## Tier Resolution
-
-```go
-type TTLTier struct {
-    Name      string
-    Duration  time.Duration
-}
-
-func EngineTier(engineName string) TTLTier {
-    if override := ttlOverrides[engineName]; override > 0 {
-        return TTLTier{Name: engineName, Duration: override}
-    }
-    return defaultTiers[engineName] // from hardcoded map above
-}
-```
-
-## New Files
-
-### `internal/cache/engine_cache.go`
-`EngineCache` struct wrapping `*Cache` with tier-aware `Get/Set` methods:
-
-```go
-type EngineCache struct {
-    cache     *Cache
-    overrides map[string]time.Duration
-    tiers     map[string]TTLTier
-}
-
-func (ec *EngineCache) Get(ctx context.Context, engine, queryHash string) (CachedEngineResponse, bool)
-func (ec *EngineCache) Set(ctx context.Context, engine, queryHash string, resp contracts.SearchResponse)
-```
-
-### `internal/cache/tiers.go`
-Tier definitions and `EngineTier(engineName string)` function.
-
-## Modified Files
-
-### `internal/cache/cache.go`
-- Rename `Key()` to `QueryHash()` and add `Engine` prefix externally
-- `Get/Set` remain for favicon caching (unchanged)
-
-### `internal/search/service.go`
-- Replace `*Cache` with `*EngineCache`
-- Parallel cache lookups with goroutines
-- Stale-while-revalidate background refresh
-- Merge collected responses
-
-### `internal/config/config.go`
-Add `TTLOverrides` field:
-
-```go
-type CacheConfig struct {
-    // ... existing fields ...
-    TTLOverrides map[string]time.Duration
-}
-```
-
-## Config Example
-
-```toml
-[cache]
-enabled = true
-url = "valkey://localhost:6379/0"
-default_ttl = "5m"
-
-[cache.ttl_overrides]
-wikipedia = "48h"
-reddit = "15m"
-braveapi = "2h"
-```
-
-## Error Handling
-
-- **Cache read failure**: Treat as cache miss, fetch fresh
-- **Cache write failure**: Log warning, continue without caching for that engine
-- **Background refresh failure**: Log error, discard (stale data already returned)
-- **Engine failure**: Continue with other engines, report in `unresponsive_engines`
-
-## Testing
-
-1. **Unit tests** for `QueryHash()` consistency
-2. **Unit tests** for `EngineTier()` with overrides
-3. **Unit tests** for `isStale()` boundary conditions
-4. **Integration tests** for cache hit/miss/stale scenarios using mock Valkey
-
