/* Ante — site identity.
   Palette is the app's own (constants/theme.js): Zinc 950 ground, Zinc 50
   foreground, #F87171 danger as the single accent. Deliberately dark-only —
   Ante is a dark product and the site commits to that world, painting every
   colour explicitly rather than inheriting one.

   Type roles:
     Bodoni Moda    display — wordmark, page titles, the hero headline
     IBM Plex Sans  body — running text, where a didone would be unreadable
     IBM Plex Mono  utility — section markers, labels, chrome, data
   Plex Sans and Plex Mono are the same superfamily, so the pairing is a
   designed relationship rather than two faces that happen to sit together. */
