/* ============================================================================
   Genaya's Hub — shell stylesheet
   CP2 (the Today shell). Static: no backend, no auth, sample data in-page.

   POINT OF VIEW (blueprint §12, green-lit 2026-07-26):
   "A calm white page that answers 'what now?' in one glance — and opens into a
   real workbench only when she's actually working."
   Calm beats complete on Today. Function beats calm inside Bakes.

   ⚠ TOKENS ARE THE ONLY PLACE A RAW HEX MAY APPEAR IN THIS FILE.
     Everything below the token block resolves through var(). The CP2 gate is a
     hex grep proving exactly that — if you add a colour anywhere else, the gate
     fails and it deserves to.

   ⚠ NIGHT MODE IS BLACK AND WHITE (Sami's ruling, 2026-07-26). It supersedes
     the proposed warm charcoal. The honest trade is stated rather than absorbed:
     PINK LARGELY DISAPPEARS AT NIGHT. It is kept for exactly two jobs that
     nothing else can carry — the primary action, and "the hub wrote this."
     Do not reintroduce pink to night surfaces, borders, or labels.
