Go backend with server-rendered HTML/HTMX frontend, SQLite database, and filesystem image storage. Self-hostable single-binary architecture. Phase 1 — Authentication & project foundation: - Argon2id password hashing with timing-attack prevention - Session management with cookie-based auth and periodic cleanup - Login, signup (open/requests/closed modes), logout, forced password reset - CSRF double-submit cookie pattern with HTMX auto-inclusion - Proxy-aware real IP extraction (WireGuard/Tailscale support) - Configurable base path for subdomain and subpath deployment - Rate limiting on auth endpoints with background cleanup - Security headers (CSP, X-Frame-Options, Referrer-Policy) - Structured logging with slog, graceful shutdown - Pico CSS + HTMX vendored and embedded via go:embed Phase 2 — Faves CRUD with tags and images: - Full CRUD for favorites with ownership checks - Image upload with EXIF stripping, resize to 1920px, UUID filenames - Tag system with HTMX autocomplete (prefix search, popularity-sorted) - Privacy controls (public/private per fave, user-configurable default) - Tag browsing, pagination, batch tag loading (avoids N+1) - OpenGraph meta tags on public fave detail pages Includes code quality pass: extracted shared helpers, fixed signup request persistence bug, plugged rate limiter memory leak, removed dead code, and logged previously-swallowed errors.
