/* miles not files — design tokens (Phase D, approved 2026-08-19).
   Source of truth for the shadcn theme; background and docs: docs/BRAND.md, Phase D.

   shadcn vocabulary, direction A "Hauptbuch" + racing-green ladder.
   Every text/surface pair is WCAG-checked (ratios documented in the Tokenbuch
   artifact and BRAND.md); change a value only together with a re-check.

   Usage rules that live outside these variables:
   - UI font Source Sans 3: self-host the UNMODIFIED OFL files (never the Google
     Fonts CDN builds — the CDN strips the `zero` feature and all stylistic sets).
     Pinned verified build: fonts/SourceSans3-VF.woff2 (v3.052).
   - Amount/number columns: `font-variant-numeric: tabular-nums` plus
     `font-feature-settings: 'zero' 1` (slashed zero).
   - Sentient (wordmark + headlines >= 19px): unmodified WOFF2 only, no
     subsetting, no redistribution (ITF FFL) — see fonts/ and the brand README.
   - Green discipline: --primary/--brand are brand greens; the status green
     --success stays separate, and status colors never color chart series. */
