Styling hooks (data-state)

Each item exposes data-state="on" / "off", data-disabled when disabled, and data-orientation matching the group, so pressed and layout styling can be driven entirely from CSS hooks.

Toggle — A single two-state button; use ToggleGroup when you need several coordinated toggles.
RadioGroup — Use for form-based single selection from a list of labelled options.
Segmented — A tab-like control for switching between views rather than toggling formatting.
Button — Use for one-shot actions; Toggle/ToggleGroup for persistent state.
