/* =====================================================================
   Selector de fotos comun (assets/js/fotos_selector.js).

   Dos overlays con prefijo .fs- para no chocar con Bootstrap ni con las
   escenas: el selector (.fs-overlay, z-index 1080) y el visor de camara en
   vivo (.fs-cam, z-index 1095). Ambos van por encima del modal de Bootstrap
   de la app (1075) porque la agenda los abre CON su modal todavia abierto.
   Los z-index tambien se ponen inline desde el JS: aqui quedan como respaldo
   documentado.

   Moviles primero (393 px de ancho es la referencia): el selector es una
   hoja pegada abajo con bordes de 16 px; en escritorio se centra. Botones
   de 48 px de alto minimo para que se atinen con el pulgar.
