/* ═══════════════════════════════════════════════
   pixel process — app styles

   Chrome (reset, header, glitch title, tool nav, workspace, footer) comes
   from ware/shell/app-shell.css, linked ahead of this file.

   This app does NOT load ware/shell/dropdown.css. Its option list is
   position:fixed and toggles display rather than animating max-height,
   because it has to escape a clipping panel — a different widget that
   happens to share the class names. It does use the shared dropdown.js,
   which detects the fixed positioning and places the list itself.
