Build a Live Progress Ring
Combine canvas and state into a widget.
The Goal
Time to build something real: a progress ring that fills as a value grows. It blends canvas drawing with live Compose state.
An Arc, Not a Circle
A ring is really an arc. We draw a faint full circle as a track, then a bright arc on top showing the progress so far.
