Pebble-style action bar with tappable icons on the brew screens; touch sleeps while the timer runs (no accidental nudges, no idle sensor drain); shake-to-dismiss now responds to a real wrist shake; steeps can be as short as 5 seconds.
First release: custom steep times, felt pour countdown, infusion tracking with ask-on-commit increments, recents as presets, and an alarm that survives the app being closed.
