/* ═══════════════════════════════════════════════════════════════════════════
   RabbidBracket — marketing site

   RabbidByte TERMINAL mode. Requires brand.tokens.css, which every page links
   ahead of this file; all brand values are var(--rb-*) references, never
   literals. The app's default scheme (id 0 "Rabbid",
   Rabbid-Bracket/brand/color-schemes.json) matches the terminal palette
   value-for-value, so the site reads as the same product either way.

   Type system matches the app: Inter for body, JetBrains Mono for
   headings/labels/numbers, with the green ">" motif on section headings.
