Visual controls versus interaction hosts

Public Switch, RadioButton, and ordinary SliderBar are visual building blocks. For user interaction, compose through a labeled parent such as ListItem so the page exposes one large focus target and one accessibility node.

• Switch: independent binary setting, never a one-time command.
• Radio: one choice in a labeled mutually exclusive set.
• SliderBar: bounded value/progress presentation.
• ListItem slider: labeled full-row adjustment.
• IsolatedControl: compact icon + bounded value as one focus target.
• Scrubber: media seek position with time semantics.
• ControlTile: compact setting/toggle/progress surface.
• AppControlTile: prominent app, destination, or person shortcut.
