Adopt the Hangman Lab visual language (adapted from the Gitea
STYLE.md, Gitea-only mechanics excluded):
- New acid SVG mark as favicon (?v cache-bust) and navbar logo.
- Single acid accent (#d8ff3e); retune globals.css tokens to the
ink/panel/line/text/dim/danger palette; drop the cyan/violet pair
(secondary -> same acid so existing components stay on-brand).
- Fonts: IBM Plex Mono for body/UI/mono, Major Mono Display for the
lowercase brand lockup; Tailwind fontFamily + content fonts updated.
- Site-wide fixed 48px blueprint-grid backdrop + one acid sheen.
