 * ESTILOS MEJORADOS Y REUTILIZABLES PARA PÁGINAS CON TABLAS
 * ===================================================================
 * 
 * Este archivo puede ser importado en otras páginas HTML que usen 
 * la misma estructura (inventario.html, cliente.html, etc.)
 * 
 * CARACTERÍSTICAS:
 * - Mejora el loader global sin modificar styles.css
 * - Mejora el botón home sin modificar casa.css
 * - Proporciona estilos modernos para tablas DataTables
 * - Incluye skeleton loaders para mejor UX
 * - Totalmente responsive
 * 
 * USO:
 * Simplemente agrega esta línea en el <head> de tu HTML:
 * <link rel="stylesheet" href="css/inventario-frio.css">
 * 
 * Las clases específicas de inventarioFrio usan el prefijo "if-"
 * Los componentes globales (loader, home-button) se mejoran automáticamente
 * ===================================================================
