/**
 * Shim minimo para reutilizar componentes legacy (jQuery/Bootstrap 4: modales,
 * grid, formularios, botones) dentro de las vistas v2, que no cargan
 * public/css/app.css (Bootstrap). Solo cubre las clases usadas por los
 * componentes legacy que todavia se reutilizan en v2 (ej. algun modal de
 * direccion en main_address/onboarding). ModalPickupNational, ModalHelpSize,
 * ModalEnvioNacionalStatus y ButtonEnvioNacionalExcel ya tienen su version V2
 * nativa (.ep-modal-*) y no dependen de este shim.
 * No se define bajo un selector .v2-* porque Bootstrap (via jQuery) inserta
 * el backdrop directamente en <body>, fuera del árbol de componentes v2.
