/* ---- Accessibility ---------------------------------------------------------

   The floating trigger and its panel live entirely in the a11y kit
   (a11y/a11y.css + a11y/a11y.js), which mounts itself. Nothing here styles
   them, so the icon is identical on every site and cannot drift. The only
   thing a project changes is colour, via the tokens the kit already reads
   (--accent / --accent-ink / --bg / --ink).

   The one rule kept here: hide the trigger while the mobile menu is open,
   because that is this shell's concern, not the kit's. See the rule above.
