/* ═══════════════════════════════════════════════════════════════════════════
   SyncEdge Clinic — /guide design system

   Single source of truth for the static Thai handbook bundle. Every page in
   frontend/public/guide/ links this file; nothing here is app-specific to one
   page. The token values MIRROR the React app's token layer
   (frontend/src/styles/globals.css) so the handbook and the product read as
   one system: dark-ink chrome, warm-paper content, clinical teal primary.

   Before 2026-08-20 each page carried its own byte-identical copy of ~85
   lines of "Warm Clinical Ledger" CSS (cream paper, pine green, honey amber,
   Bai Jamjuree) — a palette the app has never shipped. Restyling meant
   editing 14 files; now it means editing this one.

   When a token changes in globals.css, change it here too. The mapping is
   noted per line.
