/* =====================================================================================
 * RIO — SITE PUBLIC, CHARTE « GRAPHITE » (refonte du 17 octobre 2026, SITE-REFONTE)
 *
 * Chargée APRÈS styles.css, refonte.css, information-design-v2.css et ecosystem-band.css :
 * elle redéfinit les jetons de la charte (mêmes noms : --bg, --surface, --line, --t1…t4,
 * --rio…) puis habille les composants. Les composants existants suivent sans réécriture.
 *
 * Thème sombre seul. Graphite au lieu du noir, halo ardoise en CSS (aucun WebGL), cartes de
 * verre à filet d'un pixel, pilules, capsule de navigation flottante, feuille claire à coins
 * de 48 px, pied de page éclairé par le haut.
 *
 * DEUX ÉLÉMENTS NE CHANGENT PAS D'ASPECT : la maquette animée (.mock) et le schéma
 * « Comment ça marche » (#fonctionnement). Ils redéclarent l'ancienne palette sur leur
 * conteneur (bloc « Conservés » ci-dessous), et les règles nouvelles qui pourraient les
 * atteindre (.btn, section, h2, p) les excluent par `:not(#fonctionnement *)`.
 *
 * Mieux que la référence : zones tactiles ≥ 44 px, champs de 48 px en 16 px,
 * prefers-reduced-motion complet, barre d'action mobile, contrastes AA.
 * ================================================================================== */
