- A nested instance inside a main component can be exposed (`component.exposeInstance`, an
"Expose properties to instances" toggle in its panel); the main's instances then list it by
name with its variant and component property controls, recursively for exposed instances
inside it. Values set there are nested overrides and survive main edits.
- `instance.exposed {id}` lists an instance's exposed nested copies (for the CLI and MCP).
