/*
 * style.css — Estilos comunes del módulo pulsadores (domo_camper)
 *
 * Lo enlazan los paneles que comparten el mismo aspecto: _interruptores.php
 * (Interior/Exterior) y menu.php. Así el estilo vive en un solo sitio.
 * Compatible con el Samsung KitKat (sin grid/clamp/inset; px, -webkit-).
 *
 * Las clases del menú van bajo ".menu"/".topbar" y las del panel de
 * interruptores bajo ".grid" para que no se pisen entre ellas.
