// E28 review D5 + L5 + D6: the Plex player's settings panel. Its section switch was a row of
// `aria-pressed` buttons (now an ARIA tab list on `ui/Tabs`), its rows sat under the 44 touch target,
// its on/off rows were a hand-laid label (now `CheckRow`), and its sliders and colour wells had no
// accessible name — the visible label beside them was not tied to them.
