dynamic-island-macos — a native macOS Dynamic Island in Swift that lives in the notch. shows Spotify off the app's own broadcast rather than polling, mirrors a real folder through FSEvents so there's never a second copy of the state, and runs an on-device voice assistant. the part i'm proud of is a performance fix: rewriting the observation graph and moving thumbnail decoding off the main thread took median CPU from about 15% to about 4%
