Compose Ui

This surfaces all the canonical Jetpack Compose patterns in one place: state hoisting with value/onValueChange pairs, modifier parameters as first optional arg, remember versus derivedStateOf for performance, and theming through MaterialTheme instead of hardcoded values. You'd invoke this when writing new Composables or refactoring existing ones that feel janky or hard to test. The guidance is opinionated but correct, especially the lambda stability notes and the insistence on stateless components wherever possible. If you're past the tutorial phase but still occasionally wonder why your list stutters or your previews break, this will catch most of the gotchas before they ship.
