 * PALETTE IMPOSÉE : rouge, gris, blanc, noir. Aucune autre teinte.
 *   - Rouge = couleur d'accent unique (actions principales, état actif, favori,
 *     danger). On nuance le danger par une variante plus sombre du même rouge.
 *   - Gris = toute la hiérarchie de surfaces et de textes secondaires.
 *   - Blanc / noir = fonds et textes selon le thème.
 * Les puces d'IA n'ont PAS de couleur propre : elles utilisent des niveaux de
 * gris (classes .tone-0..3), la plus intense tirant vers le rouge.
 *
 * Thèmes pilotés par [data-theme] ; bascule auto via JS.
 * La variable sentinelle --bp-loaded sert au garde-fou de décompression (§2).
