Why brightness HUD is glanceable in NotNotch
brightness HUD is sized for a closed-notch chip or a short open panel, not a document window. Brightness changes can appear as a notch companion instead of the default overlay.

Closed shows the live state. Open is for the next action. brightness HUD should make sense in both.
Motion
Animations stay short. Reduced-motion users should still understand brightness HUD without the demo loop.
