```

- text density: Stores density as text.
- int controlHeight: Stores control height as int.
- int radius: Stores radius as int.
- int borderWidth: Stores border width as int.
- int emphasisBorderWidth: Stores emphasis border width as int.
- int minimumStateCueThickness: Stores minimum state cue thickness as int.
- int contentInset: Stores content inset as int.
- int iconSize: Stores icon size as int.
- text diagnostic: Stores diagnostic as text.
- yuiCoreRenderMetrics(text density, int controlHeight, int radius, int borderWidth, int emphasisBorderWidth, int contentInset, int iconSize, text diagnostic): Yui core render metrics.
- ValidationIssue() returns text: Validation issue.
- Describe() returns text: Describe.

## Use yuiCoreRenderMetrics

A complete small caller. Values are illustrative; check the returned result and package requirements before connecting live resources.

Verification: type checked

```yh

Extract the example archive beside the yeho and dolphin checkouts. This example requires those source dependencies and a current developer compiler.

Package presence and a declaration do not establish support on every host. Host services need their platform and lifecycle setup.
