/* H-ED Files — a steel filing drawer of grey report forms in manila folders.
   Loaded only on files.html, after site.css; tokens come from site.css.
   Motion is stepped (steps()) like cutout animation. The only glow is the
   non-terrestrial tab's Zogarium dot. prefers-reduced-motion and the site's
   motion switch are handled by site.css's global rules, which cut every
   animation here to its end frame. Class names are page-local (.case, not
   the home page's .dossier). */
