   English Coach — design system « Trio »
   Inspiré de PRIMUS ERP (Zodiac) : surfaces planes, rayons nets, ombres sobres,
   titres Segoe UI Light, libellés espacés dorés, filet or → jaune → fuchsia.
   Règles d'interaction : fuchsia = survol / focus, jaune = élément actif.
   Un jeton, un usage : toute nouvelle règle réutilise un --*.
   Thèmes : data-theme="light|dark" (ou système), data-accent, data-density.
