/* ============================================================================
   OTT-SYS DS — tokens (Portal, P4-E1)

   Seul endroit qui définit l'identité visuelle : couleurs, typographie,
   espacements, rayons, ombres, mouvements. layouts.css et components.css ne
   consomment que ces variables. Référence : docs/architecture/P4_PRODUCT_ARCHITECTURE.md § 19.

   Thèmes : clair par défaut ; sombre selon la préférence système, ou forcé par
   data-theme="dark" sur <html> (choix mémorisé localement par /js/theme.js,
   jamais transmis au serveur). data-theme="light" force le clair.

   Polices auto-hébergées (SIL OFL 1.1, licences dans public/fonts/<police>/LICENSE.txt) :
   aucune requête externe (CSP font-src 'self').
