/* M3 Design — Galería Isotope (isogallery): what every layout shares.
   The layouts live in layouts/<name>/option.css; this file is the frame they
   work in: the measures per device, the filters, the pictures, the lightbox.
   Nothing here depends on the script: the canvas of the builder runs none, and
   a page whose script never arrives still shows every picture. */
