   Brand: indigo #1E2A4A · amber #E8A33D · paper #FAF9F7
   Type:  Fraunces (display) · Plus Jakarta Sans (body) — same as the app

   Design system notes:
   · Brand colours (--indigo, --amber, --paper, --ink…) are FIXED — the hero,
     footer, and page-hero sections are permanently dark by design and must
     never shift with the reader's OS theme.
   · Semantic tokens (--bg, --text, --surface…) are what the page BODY, nav,
     and prose sections use — these flip automatically in dark mode via
     prefers-color-scheme, so the reading experience adapts while the brand
     sections stay put. ──────────────────────────────────────────────────── */
