Adds a Kafka-hosted favicon proxy at /favicon/<domain>:
- Fetches favicon.ico from the target domain
- In-memory cache with 1-hour TTL and ETag support (304 Not Modified)
- Max 64KB per favicon to prevent memory abuse
- Privacy: user browser talks to Kafka, not Google/DuckDuckGo
New "Self (Kafka)" option in the favicon service selector.
Defaults to None. No third-party requests when self is chosen.
Before: every HTMX response returned the full results_inner template
(~400 lines of corrections, meta, pagination, back-to-top) even though
only the result list (#urls) changed between searches.
After:
- Corrections and results-meta use hx-swap-oob="true" — they update
in-place in the DOM without duplication, no extra payload
- #urls div carries hx-select="#urls" hx-target="#urls" hx-swap="innerHTML"
— only the result rows are extracted from the response and swapped
- Pagination forms replaced with paginate-btn buttons — JS calls
htmx.ajax() directly with select:#urls so only result rows reload
- Header search form gains hx-get/hx-target/hx-select for partial updates
on subsequent searches
Payload reduction per HTMX swap: ~60-70% (no more nav, meta, pagination,
back-to-top, htmx-indicator in the swap response body)
Add internal/httpclient package as a singleton RoundTripper used by
all outbound engine requests (search, engines, autocomplete, upstream).
Key Transport settings:
- MaxIdleConnsPerHost = 20 (up from Go default of 2)
- MaxIdleConns = 100
- IdleConnTimeout = 90s
- DialContext timeout = 5s
Previously, the default transport limited each host to 2 idle connections,
forcing a new TCP+TLS handshake on every search for each engine. With
12 engines hitting the same upstream hosts in parallel, connections
were constantly recycled. Now warm connections are reused across all
goroutines and requests.
- Add favicon service preference: None (default), Google, DuckDuckGo
- result_item.html: remove hardcoded Google favicon src, defer to JS
- applyFavicon() reads data-domain attr and sets src or display:none
- Privacy-by-default: users must explicitly opt in to any favicon service
- Add favicon selector to both the settings panel and preferences page
Each engine now has a distinctive color accent applied to its result
card (left border) and engine badge (colored left strip + text).
16 engines mapped to brand-appropriate colors:
Google blue, Bing teal, DDG orange-red, Brave red, Qwant blue,
Wikipedia dark, GitHub purple, Reddit orange-red, YouTube red,
Stack Overflow amber, arXiv crimson, Crossref navy blue.
Pure CSS via data-engine attribute — no JavaScript.
Uses the Stack Exchange API v3 (/search/advanced) to find questions
sorted by relevance. No API key required (300 req/day); optionally
configure via STACKOVERFLOW_KEY env var or [engines.stackoverflow].
Results include score, answer count, view count, and tags in the
snippet. Assigned to the 'it' category, triggered by the IT category
tab or explicit engine selection.
6 tests covering parsing, edge cases, and helpers.
The project uses pure Go HTML templates + CSS. The React frontend
(frontend/), SPA handler (internal/spa/), and prebuilt binary (kafka)
were dead weight.
Also removes the frontend replacement plan/spec docs.

Wikipedia returns HTML entities like <span> which were being
double-escaped by Go templates. Now using html.UnescapeString and
template.HTML to render properly.

- Provides HTTP handler for static file serving
- Falls back to index.html for SPA client-side routing

Reverted CSS to the known-working state at 4b0cde9, then re-applied
only the image grid styles. The duplicate .results-layout block is
intentional — it was present in the working version too.
The old 3-column layout block (referencing .left-sidebar/.right-sidebar
classes that don't exist in the HTML) was overriding the correct layout
defined earlier. Removed the stale duplicate.
Three new image search engines:
- bing_images: Bing Images via RSS endpoint
- ddg_images: DuckDuckGo Images via VQD API
- qwant_images: Qwant Images via v3 search API
Frontend:
- Image grid layout with responsive columns
- image_item template with thumbnail, title, and source metadata
- Hover animations and lazy loading
- Grid activates automatically when category=images
Backend:
- category=images routes to image engines via planner
- Image engines registered in factory and engine allowlist
- extractImgSrc helper for parsing thumbnail URLs from HTML
- IsImageSearch flag on PageData for template layout switching
- results-layout: 3-column grid (1fr | min(768px,100%) | 300px) max-width 1400px, centered
- Widen center results column to 768px max
- Right column (formerly sidebar): sticky, contains knowledge panel + related searches
- Knowledge panel: Wikipedia/infobox summary with optional thumbnail
- Related searches: clickable links to refine the query
- Empty left buffer creates balanced whitespace on large screens
- Responsive: 2-col at 1000px, 1-col at 700px
New brave.go: scrapes https://search.brave.com directly.
Extracts title, URL, snippet, and favicon from Brave's HTML.
No API key required.
Rename existing BraveAPIEngine (was BraveEngine) to avoid collision
with the new scraper. API engine stays as 'braveapi', scraper as 'brave'.
Go's regexp package doesn't support Perl lookahead (?=...). Removing
the unnecessary lookahead since each MjjYud div is self-contained.

Wrap sidebar time/type filters in a form with HTMX attributes so
filter changes trigger partial page updates instead of full reload.

Wikipedia language subdomain was derived from user input without
validation, allowing attackers to redirect requests via malicious
language values like "evil.com.attacker.com". Added a whitelist of
valid Wikipedia language codes to prevent this.

Brave API only supports offset values 0-9. When pageno > 1 with
resultsPerPage=20, offset exceeded this limit causing 422 errors.

Test GET /healthz, /, /search, /autocompleter endpoints.
Verify response codes, content types, JSON decoding, empty-query
redirect, and source URL presence in footer.
Also fix dead code in Search handler: the redirect for empty q
was unreachable because ParseSearchRequest errors on empty q first.
Move the q/format check before ParseSearchRequest to fix the redirect.
Trim or remove comments that:
- State the obvious (function names already convey purpose)
- Repeat what the code clearly shows
- Are excessively long without adding value
Keep comments that explain *why*, not *what*.
Thread source_url through: config.ServerConfig → Handler.sourceURL
→ PageData.SourceURL → template footer. Footer only shows Source
link when source_url is set.
Update LICENSE file and add AGPL header to all source files.
AGPLv3 ensures that if someone runs Kafka as a network service and
modifies it, they must release their source code under the same license.

html/template requires template names to be string literals, not field
accesses. Use {{if eq .Template "videos"}} to branch and call the
appropriate template by literal name.
Go html/template doesn't support function calls as template names in
{{template (func .Arg) .}}. Instead, precompute TemplateName in
FromResponse and use {{template .TemplateName .}} in the template.
