Token parity
Every live page should source color, spacing, radius, and type from the approved token system.
- No new hex colors without approval.
- No oversized hero copy beyond the approved display scale.
- No campaign-specific radius or shadow overrides.
Pattern safety
Reusable modules should stay structurally consistent, especially CTA lanes and proof rails.
- Hero stacks must keep the approved CTA pair.
- Tables should keep the monospace header grammar.
- Warning banners should reuse the existing review lane.
Readability posture
Typography and contrast should support fast scanning, not aesthetic experimentation.
- Muted copy must remain readable against the background system.
- Body width should stay within the approved content measure.
- Status colors must reinforce meaning, not decoration.
Exception logging
If a team needs a custom pattern, it should show up in the approval desk with a named owner and rollout plan.
- No silent exceptions.
- No post-launch justification without prior review.
- No duplicate variants solving the same layout problem.
