brightness HUD on macOS 14 Sonoma
NotNotch’s deployment target is macOS 14, so brightness HUD is built to run on Sonoma and later. Brightness changes can appear as a notch companion instead of the default overlay.

Why Sonoma is the floor
The SwiftUI notch host and several system APIs assume macOS 14. brightness HUD follows that floor.
Later systems
The same brightness HUD path is intended to keep working through macOS 27 without bumping the minimum.
