    - h1: "One per page, largest size"
    - h2: "Section headers"
    - h3: "Subsection headers"
    - body: "Default text content"
    - small: "Captions, metadata"
  violations:
    - skip_level: "h1 followed by h3"
    - wrong_weight: "Body text bold"
    - inconsistent_size: "Mixed font sizes in same context"

Validation Workflow​

Phase 1: Token Loading​

  • Load customer design tokens from configuration
  • Validate token completeness
  • Identify missing required tokens
  • Apply fallback tokens where needed

Phase 2: Compliance Check​

  • Scan generated UI for token usage
  • Identify raw values (hex colors, px sizes)
  • Flag semantic violations
  • Calculate compliance score

Phase 3: Auto-Correction​

  • Replace raw values with tokens
  • Fix semantic color misuse
  • Correct spacing violations
  • Adjust typography hierarchy

Phase 4: Reporting​

  • Generate compliance report
  • List applied corrections
  • Document remaining violations
  • Provide remediation guidance
