1/*!
2 * EXT:easyaccess – Barrierefreiheit des Readabler-Overlays
3 * Prüfbericht hochsauerlandwasser.de vom 30.09.2026, Befunde B02–B05
4 *
5 * Setzt auf dem von Readabler 1.7 erzeugten Markup auf; die Herstellerdatei
6 * readabler.js bleibt unverändert (Updates bleiben möglich).
7 *
8 * B02  Geschlossenes Panel: inert, nicht per Tab erreichbar, nicht im Barrierebaum
9 *      (zusätzlich visibility:hidden in readabler-a11y.css)
10 * B03  Panel als modaler Dialog mit Namen (aria-labelledby), Auslöser mit
11 *      aria-expanded/aria-controls, Kopf/Fuß ohne Landmarken, Profile als Schalter
12 *      (role=switch), Optionen mit aria-pressed, Bereiche als Gruppen statt role=dialog
13 * B05  Fokus beim Öffnen in das Panel, Tab bleibt im Panel, Esc schließt,
14 *      Fokus kehrt zum Auslöser zurück; Auslöser am Anfang der Tab-Reihenfolge
15 * 2.4.3 Minus-/Plus-Schaltflächen in sichtbarer Reihenfolge
16 * 3.2.2 Link-Navigator wechselt die Seite erst nach Bestätigung (Schaltfläche/Enter)
