/* My VoiceLink (client/portal/): the built-in web portal.
   Look and structure follow the blind.software account panel: dark brand header, light cards,
   folder-style tabs, strong 3px focus outlines, 4.5:1 contrast or better, light and dark modes and
   a forced-colours friendly high-contrast fallback. Selected tabs are marked by shape (a thick top
   bar and a joined bottom edge) as well as colour. */
