Colour theme is configurable at runtime from two seed colours (brand + accent); neutrals stay fixed for contrast safety. Tailwind v4 var()-based tokens let a :root:root override recolour everything with no rebuild; the 50->950 ramps are derived via a color-mix ladder. Config lives in the DB config table (admin UI: Config > Farbschema, presets + custom pickers + live preview), served on the public /event endpoint with env defaults (THEME_PRESET/PRIMARY/ACCENT), propagated live via event-updated SSE, and cached in localStorage for a no-flash boot. The keepsake export mirrors the same ladder in Rust so offline archives match the event theme. COMMENTS_ENABLED (env, default true) is a boot-time kill-switch: the backend rejects new comments with 403 and the frontend hides the comment button (feed card) and panel/composer (lightbox). Existing comments stay in the DB, hidden, and return when re-enabled. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
