/* ============================================================================
   V15.2 :: tanda-v152-recpc-premium
   REDISEÑO COMPLETO del modal Recomendaciones Post-Carrito.

   Antes (V13): el CSS existía pero NO estaba cargado en _Host.cshtml.
   Bug detectado por Lauti via screenshot - se veía como texto plano sin estilos.

   Ahora (V15.2): diseño premium consistente con resto del sistema:
   - Modal centrado con backdrop blur
   - Stepper visual del flow (Carrito → Recomendaciones → Pago → Listo)
   - Cards con hover, sombras, gradientes
   - Botones primarios con CTAs claros
   - Responsive mobile
