/* Accessibility panel - self-hosted stand-in for the third-party overlay
 * (UserWay) used on the old practice website. Two halves:
 *   1. The panel itself, injected into the header by a11y.js. It reuses the
 *      menu-panel and band-btn patterns so it follows the scheme tokens.
 *   2. The effect classes a11y.js sets on <html>. The forced light/dark
 *      scheme is NOT here - it is the data-scheme token blocks in styles.css.
