 * Se carga DESPUÉS de site.css (ver frontend/assets/AppAsset.php) para

 *
 * NOTA: existe una copia sincronizada manualmente en
 * backend/web/css/buddy-ui.css — replicar cualquier cambio de tokens/
 * overrides globales (bloques 1-3) ahí también. Los bloques de componentes
 * específicos del frontend (sidebar, header, badges, cards, etc.) que se
 * vayan agregando en hitos posteriores no necesitan replicarse si el
 * backend no usa ese componente.
