## Summary
- add the Spec 324 package for UI Productization Coverage Guardrails, including spec, plan, tasks, and requirements checklist
- update Spec Kit templates and implementation prompts so future work must record UI surface impact, including navigation and Filament panel/provider surfaces
- harden the UI productization coverage guard script and add the validation helper for lightweight guard execution
- document the proportional guardrail flow in the UI/UX enterprise audit README
## Validation
- not run in this step
- change set is docs/tooling/governance only; no product runtime implementation included
