Phase 6: FINAL REVIEW — Visual validation and report

When

After Phase 5 audit passes. Last step of the design pipeline.

Input (from Phase 5)

  • Audited components with all Critical/Major issues resolved.
  • WCAG AA validated. Anti-AI-slop checks passed.
  • design-system.md as the source of truth.

Steps

  1. Screenshot light mode — Use mcp__fuse-browser__browser_screenshot with colorScheme: "light" on every key page/component via localhost.
  2. Screenshot dark mode — Re-shoot the same pages/components with mcp__fuse-browser__browser_screenshot colorScheme: "dark" (handles both .dark class and prefers-color-scheme, no manual toggle).
  3. Compare 3 declared elements — For each page, compare these 3 elements against the inspiration site screenshots from Phase 3:
    • Color contrast and readability.
    • Component spacing and alignment.
    • Animation and hover state consistency.
  4. Cross-viewport check — Screenshot at mobile, tablet, and desktop widths using mcp__fuse-browser__browser_screenshot with viewports: ["mobile", "tablet", "desktop"] (one call, responsive set).
  5. Fix gaps — If comparison reveals issues, use mcp__gemini-design__modify_frontend to fix. Maximum 2 fix cycles.
  6. Generate report with:
    • Side-by-side light/dark screenshots.
    • List of verified components with status (pass/fail).
    • Any remaining Minor issues from Phase 5 audit.
    • Summary of fixes applied during this phase.

Output

  • Final report with light/dark screenshots at 3 viewports.
  • All components verified visually. Gaps fixed (max 2 cycles).
  • Design pipeline complete — HTML/CSS delivered.
