/**
 * Directorio Farmacéutico - Core Styles
 *
 * Estilos mínimos funcionales que NO dependen del diseño visual.
 * Estos estilos son para funcionalidades básicas como:
 * - Estados de carga (loading)
 * - Mensajes de feedback AJAX
 * - Accesibilidad (screen reader)
 * - Estados de error/éxito básicos
 *
 * Nota: Si estás usando el tema dirfarm-theme con Tailwind,
 * estos estilos NO se cargarán (el tema maneja todo el diseño).

 * @package Directorio_Farmaceutico
