   css/accessibility-modal.css

   Per-Board Accessibility modal styling (W2 of the 5-worker dispatch
   shipping WCAG 2.1 AAA per-board accessibility, 2026-05-22).

   Standalone — NOT @imported into builder.css (keeping the builder
   bundle small + lets W6 conditionally load only when the pill is
   present). The class prefix is `a11y-modal-*` so collisions with
   the existing recipient-side `use-a11y-*` panel are impossible.

   Palette pulled from :root variables defined in builder.css
   (--amber / --ink / --surface / etc.). The modal renders correctly
   on top of any page that ships that root.

   Tap-target floor on every interactive control is 44px — the modal
   itself must hit WCAG 2.5.5 AAA, regardless of what the author
   configures for the BOARD inside it.
