FormaRadioButton

A stateless single-choice control with hoisted selected state; group several with Modifier.selectableGroup() and pass onClick = null when the row owns selection.

Accessibility

48dp touch target via Material 3's minimum interactive component size; apply Modifier.selectableGroup() to the container so screen readers announce the set and position (e.g. "2 of 4"), and prefer row-level Modifier.selectable with onClick = null so the whole row is one accessible target.
