/* ─── TOKENS — charte « Le trait bleu » ───
   Base : bleu cordeau (confiance, services pro) sur encre/papier.
   L'orange crayon est RÉSERVÉ aux CTA principaux et aux coups de
   crayon — nulle part ailleurs (effet d'isolation : un accent qui ne
   sert qu'à l'action reste visible). Ratios WCAG AA vérifiés au calcul,
   voir docs/charte-couleurs.md. Aucune couleur en dur hors de ce bloc
   (exceptions sémantiques : --ok, --star). */
