  PARA EL AGENTE DE IA (Antigravity / Gemini / Claude):
  Lee CONTEXT.md antes de modificar este archivo.

  SECCIONES (buscar por número):
    1.  Variables CSS y Reset   ← CAMBIAR PALETA AQUÍ (:root)
    2.  Utilidades globales     ← .container, .btn, .section-title
    3.  Tipografía base
    4.  Header & Navegación
    5.  Sección Héroe
    6.  Productos Swiper        ← .product-card
    7.  Banner de Impacto
    8.  Categorías              ← .category-card
    9.  Por Qué Elegirnos       ← .feature-card
    10. Testimonios             ← .testimonial-card
    11. Newsletter
    12. Footer
    13. Chatbot Widget          ← .chat-widget, .chat-bubble
    14. Toast de Carrito
    15. Animaciones             ← keyframes, .scroll-reveal
    16. Media Queries           ← tablet ≤900px, móvil ≤600px
    17. Cart Drawer             ← .cart-drawer, .cart-item (final)

  REGLAS PARA EL AGENTE:
    - NUNCA hardcodear colores: siempre usar var(--)
    - Nuevas secciones: agregar CSS antes de las Media Queries
    - Nuevos breakpoints: agregar al final del archivo
    - Usar border-radius con var(--radius-*) para consistencia
