/* ==========================================================================
   crypt — feuille de style unique.

   Organisation :
     1. Tokens (couleurs, typo, espaces, rayons, ombres)
     2. Base & typographie
     3. Chrome applicatif (topbar, layout, footer)
     4. Formulaires & boutons
     5. Cartes, tableaux, métriques
     6. Graphes & légendes
     7. Composants divers (chips, alertes, spinners, éditeur)
     8. Login
     9. Utilitaires & motion

   Les couleurs de données (--series-*, --good/--critical/--warning) viennent
   d'une palette validée pour le daltonisme et les contrastes : ne pas les
   retoucher sans revalider. Le reste (surfaces, marque, ombres) est libre.
