Integration Notes

• This component composes cleanly with layout primitives such as Card, Grid, Row, and Column.
• Prefer controlled state from Python when the value matters to your business logic or backend query layer.

Responsive Notes

Check the component inside a realistic layout, not only in isolation, so spacing, overflow, and action density stay comfortable on smaller screens.

Accessibility Notes

Pair this component with clear visible copy and predictable state changes so keyboard and assistive-technology users are not surprised.
