Phase 1: Documentation + CSS Verification

Adds comprehensive documentation for WaysNX UI Kit design tokens and integration patterns.

Added

• docs/theming/TOKENS.md - Complete design token reference (44 tokens, source-verified)
• docs/integrations/EXISTING_APPS.md - Integration strategies with technically accurate CSS guidance

Changed

• README.md - Updated Design System section with accurate token count

Verified

• ✅ All 44 token values source-verified against packages/ui-core/src/styles/tokens.css
• ✅ Token counts accurate (20 colors, 5 spacing, 8 typography, 4 radius, 5 shadows, 2 component)
• ✅ CSS visual inspection in Storybook (all colors correct, no inconsistencies)
• ✅ Storybook builds successfully
• ✅ P0 regression tests pass (no regressions introduced)
• ✅ Token inheritance verified in Button.css and Sidebar.css source

Technical Accuracy

• CSS cascade layer documentation uses correct terminology (precedence, not specificity)
• Font-size table shows actual var(--wx-accessibility-font-scale, 1) formulas
• Integration guidance reflects actual build setup (tsup bundling)
• Verification claims limited to sampled components

Scope

• Documentation only (no code changes)
• Phase 1 of incremental UI Kit improvements

Review: Approved

Reviewed the Phase 1 documentation changes for WaysNX UI Kit.

Verified

• README updated with the correct 44-token reference and links to the new documentation.
• Design token documentation and counts are consistent with the stated source verification.
• CSS cascade-layer guidance correctly distinguishes cascade precedence from selector specificity.
• Integration guidance reflects the documented build setup and clearly identifies the limitations of the Shadow DOM example.
• Changes are appropriately scoped to documentation; no component logic changes are included.

Validation

• Build and type-check: Passed.
• Security and repository checks: Passed.
• Dependency audit: Reports an advisory-only, non-blocking failure; review its findings separately.
• Confirm Chromium, Firefox, and WebKit P0 regression jobs have passed before merging.

Recommendation: Approve and merge once the remaining regression-check statuses are confirmed. No further documentation changes are requested based on this review.
