Build me a sleek macOS app that makes the MacBook notch actually useful.

I want it to show useful live info in and around the notch, like what is playing now, the weather, calendar events, Bluetooth connection alerts, and simple eye break reminders. It should also let me adjust audio quickly, including per app volume and device volume, right from the notch when possible. Add a nearby share style feature so I can send files, photos, videos, websites, and other stuff from Android to my Mac, plus a file shelf for keeping and moving files around easily.

It should include a better window snapping experience than the default one, with customizable snap zones that remove the awkward gaps. If you can, also add a lock screen view with music, weather, and calendar info, and a simple caffeinate button to keep the Mac awake.

Make it feel polished and native on macOS, with permissions handled clearly on first launch, and if you need to check anything current, look up the latest docs online.
