/*!
 * Softbit UI 1.0 — kit de design comum a todos os projetos Softbit.
 *
 * Um projeto usa este ficheiro tal e qual e define só o seu tema:
 *   :root { --sb-accent: #D45B2E; --sb-nav: #2B1D16; }
 * Tudo o resto (suave, hover, foco, contraste do texto) deriva destas duas cores.
 * Modo escuro automático (prefers-color-scheme) ou forçado com <html data-mode="dark|light">.
 *
 * Componentes: sb-app (menu lateral + topo), sb-btn, sb-card, sb-field, sb-input, sb-select, sb-toggle,
 * sb-table, sb-badge, sb-dot, sb-alert, sb-modal, sb-tabs, sb-kpi, sb-empty, sb-avatar, sb-auth, sb-palette.
