/* shell.css: the bar, the app wrapper and the device frame of Harmony Lab (web spec 3.2, 4.1 to 4.4).
   Loaded by every static page and by the React root layout. Self-contained on purpose: the bar
   and its dialog set margin, padding, font, colour and border on everything they contain, so
   they look the same under lab.css (*{margin:0;padding:0}, global button and :focus-visible)
   and under app/globals.css (another button reset, a green focus ring, .chrome-label).
   Tokens are --hl-* only; never --accent, --text, --panel*, --led-* or --radius.
   No window media queries and no window units outside the app wrapper (tests/native-css.test.js):
   the bar adapts through attributes set by shell.js (data-narrow, data-tiny, data-hl-short). */
