- Add internal/views/ package with embedded templates and static files - Go html/template with SearXNG-compatible CSS class names - Dark mode via prefers-color-scheme, responsive layout, print styles - HTMX integration: - Debounced instant search (500ms) on the search input - Form submission targets #results via hx-post - Pagination buttons are HTMX-powered (swap results div only) - HX-Request header detection for fragment vs full page rendering - Template structure: - base.html: full page layout with HTMX script, favicon, CSS - index.html: homepage with centered search box - results.html: full results page (wraps base + results_inner) - results_inner.html: results fragment (HTMX partial + sidebar + pagination) - result_item.html: reusable result article partial - Smart format detection: browser requests (Accept: text/html) default to HTML, API clients default to JSON - Static files served at /static/ from embedded FS (CSS, favicon SVG) - Index route at GET / - Empty query on HTML format redirects to homepage - Custom CSS (gosearch.css): clean, minimal, privacy-respecting aesthetic with light/dark mode, responsive breakpoints, print stylesheet - Add views package tests
