/* ============================================
   DOMIDELIS - CARRITO
   Páginas: index.html (única consumidora actual)

   DEPENDENCIAS (cargar ANTES este archivo):
   - styles.css → variables, reset, header base,
     y los KEYFRAMES que este archivo usa:
     popIn (cart-float.visible), fiestaCarrito
     ★ NO borrar esos keyframes de styles.css

   ORDEN DE CARGA en index.html:
   styles.css → home.css → cart.css
   → modal-personalizacion.css → anuncios.css
   (cart.css debe ir ANTES de modal-personalizacion
    y anuncios, como estaba §11 en el original.
    El orden entre home.css y cart.css es libre:
    no comparten selectores.)

   Migrado desde styles.css:
   - Bloque "HEADER CART — solo página principal" (§6)
     ★ Incluye .main-nav y links "Cómo pedir": es un
       bloque continuo, se migra entero. En una futura
       fase de limpieza podría partirse.
   - §11 Carrito flotante y panel (completo)

   NOTA: el orden interno replica EXACTO el documento
   original para no alterar la cascada.

   BUG CONOCIDO (HTML, no CSS): id="cart-counter"
   duplicado en index.html (header y cart-float).
   El CSS usa clases (.header-cart-count /
   .cart-counter) así que no afecta esta migración.
   Corregir en fase de limpieza junto al JS.
