   magmacrunch media — retro dropdown
   ware/shell/dropdown.css

   The absolute-positioned, max-height-transition dropdown used by
   album-art-maker and media-search. Pair it with ware/shell/dropdown.js.

   pixel-process deliberately does NOT load this. Its options are
   position:fixed and toggle display rather than animating max-height,
   because they have to escape a clipping panel — a genuinely different
   widget that happens to share class names. It keeps its own rules and
   uses only the shared JS.

   Tokens, all with defaults matching album-art-maker:
     --dd-border-w   border width on the trigger and the option list
     --dd-accent     open/hover colour
     --dd-glow       accent at low alpha, for the box-shadow
     --dd-tint       accent at very low alpha, for option hover/active fills
     --dd-font-size  trigger label size (options are always 7px)
