/* copié de scalefast-devis@01362b0 (public/dashboard.css) — réduit au socle BIEX.
   BIEX-32 — charte BIEX du 27/09 (docs/wiki/charte.md) : UNE marque, TROIS
   registres posés sur `html[data-register]` (kids, explorer, adult). Les blocs
   de TOKENS ci-dessous (`:root` = adulte, `kids`, `explorer`, sombre adulte)
   sont les SEULS endroits où une couleur s'écrit en hex : partout ailleurs une
   couleur est une variable (test/charte.test.js). Fredoka + Nunito
   self-hosted (aucune requête Google Fonts). Utilitaires `u-*` à la fin :
   spécificité 0-1-0, AUCUN !important. Aucun style inline nulle part (CSP
   `style-src-attr 'none'`) : le dynamique passe par `data-sfs`. */
