 *  Archivo de componentes reutilizables (widgets) que se usan

 *  autocontenido — puedes copiarlos individualmente.
 *
 *  📚 ÍNDICE
 *  1. BOTONES                → .btn, variantes y tamaños
 *  2. CARDS DE PRODUCTO      → .product-card (catálogo, home)
 *  3. TAGS / CHIPS           → .tag (filtros, categorías)
 *  4. MODAL                  → .modal-overlay, .modal (productos)
 *  5. TOAST                  → notificaciones flotantes (UI.toast)
 *  6. FORMULARIOS            → .form-control, .form-error
 *  7. LOADER / SKELETON      → spinners y placeholders animados
 *  8. EMPTY STATE            → vista para "sin resultados"
 *  9. DIVIDER                → separador decorativo entre secciones
 *
 *  ⚠️  Depende de variables.css (debe cargarse después).
 *  ⚠️  No contiene estilos de PÁGINA (eso va en layout.css).
 *
 *  Ejemplo de uso en HTML:
 *      <button class="btn btn-primary btn-lg">Comprar</button>
