/* ═══════════════════════════════════════════════════════
   THOUGHT SEED — document pages (/about, /privacy)

   These two pages are STATIC HTML in public/, deliberately outside the
   React app: the SPA serves one hardcoded pre-boot fallback containing
   the LANDING copy, so a crawler asking for /about would be handed the
   landing page. See the crawlability section of CLAUDE.md.

   Being outside the app means they cannot use Tailwind or src/index.css,
   so the tokens below are a hand-copy of the ones there. Copied, not
   eyeballed — the values must match src/index.css and
   src/styles/tokens.css exactly, or these pages read as a different
   website sitting on the same domain.

   Shared by both documents rather than inlined twice; two copies would
   drift the first time a token changed.
