Reimplements the Flask app as a Go HTTP API (chi + modernc sqlite) with a minimal vanilla-JS frontend in web/. Endpoints mirror the original Flask routes but return JSON instead of HTML. - auth: login/logout/register/sessioninfo/headerbar with crypto/rand tokens - entry: paginated feed (single JOIN), create with image scaling - user: profile, userinfo; delete still a stub - requireAuth middleware passes uid via context - notes/api.md documents the API and schema Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
