/* SIMBIA - hoja de estilos del dashboard.
 *
 * Principios:
 *   - Una pantalla por modulo. El usuario siempre sabe en cual esta.
 *   - El color codifica una sola cosa por contexto: verde/rojo = cumple o
 *     no cumple; los sellos de procedencia tienen su propia paleta.
 *   - La explicacion larga vive en <details class="ayuda"> o en el modulo
 *     "Modelo": la pantalla de trabajo muestra datos y acciones.
