/* ── Accessibility widget (public site) ─────────────────────────────────────
   A floating button + panel of display adjustments. Every effect is a class
   on <html> (set by a11y.js, remembered in localStorage) and targets the
   page's content only — `body > :not(.a11y-root)` — so the widget itself
   stays readable and operable whatever is switched on. Filters in particular
   must never touch the widget: a filter on an ancestor would also break its
   position: fixed. */
