volume HUD on macOS 14 Sonoma
NotNotch’s deployment target is macOS 14, so volume HUD is built to run on Sonoma and later. Volume overlays replace the stock macOS HUD when enabled.

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