Same design, layout, URLs and features as the PHP version: browse grid, image view with AJAX comments, BBCode, likes, uploads (file, URL and bookmarklet), quicktagger, profile, block list, inbox, invites, Hall of Ducks, Truhe, abuse reports and the admin tools. - Parameterized SQL, escaped templates (askama), argon2 passwords, server-side sessions, CSRF tokens on every write, strict script CSP - SSRF-safe remote image fetching, magic-byte upload checks - Self-hosted captcha replaces reCAPTCHA v1; analytics/social widgets removed - Vanilla JS replaces jQuery and its plugins with the same DOM behaviour - Reverse proxy support (frontend_path, trust_proxy, secure_cookies) - Admin CLI: admin, settings, invites See README.md for running it and the full list of changes.
