/* =====================================================================
   ANTAEUS — web design tokens (Slate)
   ---------------------------------------------------------------------
   A port of src/theme/colors.ts and docs/design-reference/SLATE_SPEC.md.
   The app is the source of truth: when a token changes there, change it
   here with the same role. This file introduces NO colour the app does
   not have.

   What changed from tokens-10.css (the Ledger port), 2026-10-09:
     · ONE family, Mona Sans (OFL, self-hosted, unmodified woff2). Semi
       Condensed for figures and display, normal width for prose and
       labels. Barlow and Plex Mono are retired.
     · Labels are sentence case, no tracking, no text-transform.
     · The coach's tick is teal (`tip`), not amber.
     · Light climbs TOWARD white: canvas #EEEEF1 -> card #F9F9FB -> #FFF.
     · Groups are rounded panels (20), actions 12, small controls <=10.
   Class names are kept from tokens-10 so the Build Log renderer
   (functions/_lib/render.js) and the tools pages keep working.
