State ownership and DOM target

Concern	Contract
State	No component state contract is exposed; the application owns the rendered content and surrounding behavior.
DOM target	Public passthrough props target the component root. Treat nested elements and private class names as implementation details.

Anatomy and related components

This component exposes one public component root rather than a compound member API.

Limitations

Avoid FocusTrap when using feedback components as primary page layout.

Use only the documented props, entry points, and compound members. Internal DOM nesting and CSS class names can change without becoming part of the public component contract.

Accessibility

Traps `Tab` and `Shift+Tab` within focusable descendants.

Traps `Tab` and `Shift+Tab` within focusable descendants.
