Contrast and Non-color Cues
Text, meaningful graphics, controls, focus, and states meet relevant contrast thresholds and do not depend on color alone.

Intent
Preserve legibility and state meaning across vision differences, displays, and environmental conditions.
Checks
- Measure every semantic color pairing used and inspect state cues without relying on hue.
- Review hover, active, focus-visible, selected, disabled, error, and success states through source, design-state inspection, or manual rendered review when practical.
Warnings
- Token names do not prove the actual foreground and background pairing passes.
- A foreground that passes on the default surface may fail when a state changes only the background.
Exceptions
- Logotypes and incidental disabled content follow the specific WCAG exceptions.
