   Virat Mohan — shared brand tokens
   https://viratmohan.com/brand/tokens.css

   The homepage (src/pages/index.astro + src/styles/global.css) is the single
   source of truth. This file MIRRORS the tokens in global.css so standalone
   pages and external apps can wear the same look. Keep it in sync:
   `node scripts/check-brand-tokens.mjs` fails if any value drifts.

   One authored look, no dark mode — a poster is a fixed artifact.
