/* =============================================================================
   FACTURALAYA ERP — CONFIRM / DIALOG / PROMPT (estilos del componente reusable)

   Sistema visual moderno con:
   - Backdrop con blur sutil y fade
   - Dialog con scale-up + slide-up
   - Tonos de color por tipo (info / exito / advertencia / peligro / error)
   - Botones con jerarquia clara (peligro destacado en rojo, primario azul)
   - Input/textarea estilados con focus accent, contador y error inline
   - Mobile responsive (toma 92% del viewport en pantallas chicas)
   - Reduced motion respetado
   - Dark mode ready (variables CSS)

   Personalizable por modulo via variables CSS (--fl-confirm-*).
   ============================================================================= */

/* ---------- Variables (defaults, los modulos las pueden sobrescribir) -----
   Los colores heredan del contrato global de paleta del ERP (--fyerp_paleta_*)
   con fallback a la familia indigo/slate: cada modulo tiñe sus dialogos con su
   propia paleta sin tocar este archivo. ------------------------------------ */
