📝 WalkthroughWalkthroughThe Sana theme now uses base-palette CSS variables, expanded neutral ramps, Sana-specific ChangesSana theme token alignment
Estimated code review effort: 3 (Moderate) | ~25 minutes Merge Risk: 🟡 Moderate · up to The PR improves Sana theme portaling, but it can leave popups using stale Sana styling after the theme is cleared, and the updated example lacks an accessible name for its input. The associated test setup is also fragile, so these issues should be addressed before merging. Possibly related PRs

Use the component test helper and avoid positional DOM access.
CanvasProvider is an element component. This test calls render directly and reads container.firstElementChild, which depends on wrapper position. Start the component spec with verifyComponent(CanvasProvider, {}), then target the forwarded element through the helper or a named query.
As per coding guidelines, “Start element-component specs with verifyComponent(Component, {})” and prefer semantic assertions over “DOM-structure or index assertions.”

Skipped verifyComponent(CanvasProvider) — CanvasProvider is not an element component (createComponent/forwardRef/as). That helper asserts ref forwarding and as, which this wrapper does not support.
The test now queries via closest('[data-theme]') instead of container.firstElementChild.

@mannycarrera4, verifyComponent(CanvasProvider, {}) does not apply. CanvasProvider is a plain function component and does not support the helper contract.
However, the current PR state still uses container.firstElementChild at Line 15. The inspected file does not contain closest('[data-theme]').
Please push the revised query, or update the PR branch. The remaining concern is only the positional DOM assertion.

…ample Sana's selected Menu.Item/Menu.Option fg/surface colors were dropped when reworking the theme to avoid var() self-reference cycles, silently regressing portaled popups back to classic blue. Restore them via the neutral ramp (no cycle risk, since they target different CSS variables). Also fix the SimplifiedSanaSetup story's Menu.Option, which used `id` instead of `data-id` so initialSelectedIds never matched, masked by a hardcoded aria-selected prop. Additionally, replace hand-typed Sana CSS variable name strings with canvas-tokens-web's own `base.sana` export to avoid drift. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>

Pull request overview
Ensures Sana theming works correctly for portaled popup content by forwarding the data-theme attribute (in addition to brand CSS vars) so token styles scoped to [data-theme="sana-canvas"] apply to popup stack containers rendered under document.body.
Changes:
- Forward
data-themefromCanvasProviderto popup stack containers via a new context consumed byusePopupStack. - Refine Sana theme token forwarding to avoid
var()self-reference cycles and expand neutral/alpha ramp support. - Update docs and add/adjust specs to validate the new theming + portal behavior.

Addressed: when themeAttribute is cleared, data-theme is removed from the popup container. Added a test covering the "sana-canvas" → unset transition.
