/* ============================================================================
   Marija Deck — Colour Tokens (Joycean)
   Every value is grounded in Joyce's own usage (see research/joyce-motifs.md).
   Not invented decoration: the Greek-flag-blue 1922 Ulysses cover, the warm
   ivory of book stock, sovereign gold, the greys of Dublin, and Joyce's own
   Linati/Gilbert episode schema for section-coding only.
   ----------------------------------------------------------------------------
   WCAG note (verified by scripts/wcag check): body --ink on --paper = 14.3:1 (AAA).
   --color-ink-mute = grey-600 = 5.6:1 (AA). Gold for TEXT must be gold-700 (4.57:1
   AA); gold-500 is DECORATIVE ONLY — the gold→blue gradient ribbon/hairline, never
   readable text. White (--paper) on primary-700+ passes AA (≥8:1).
