[SandObserver]

Summary

• Show the resolved palette entry and hex, with an inline swatch, for every role and every opaque semantic token, instead of pointing at a token name.
• Split the single geometry table into Layout, Controls and Corners, with controls tabulated as track against handle.
• Reduce the alert callouts to the WCAG label-level rule and the touch-target rule.
• Move the semantic values and the widget rules out of collapsed sections; keep the Settings-page style assignments and the page-scoped tokens collapsed.

Testing
All green, Docker build smoke test left to CI. No coverage change; the file carries no code.

Checklist

• Stays within the project constraints: one container, no runtime dependencies, no build step (see CONTRIBUTING.md).
• Tests added or updated for new logic, and the full suite, lint, and typechecks pass.
• Docs updated if behavior or configuration changed.
• CHANGELOG.md updated under Unreleased if the change is user-visible.
