 ## How to use
 
-- Treat this module as the visual baseline for reusable UI components in this repository.
-- Pattern contracts should reference this module instead of redefining shared visual primitives.
-- When visual behavior changes in demo/scaffold, sync the canonical rules here so host projects can reproduce the same output deterministically.
+- Treat this module as a legacy reference snapshot, not the active baseline.
+- Pattern contracts should inherit the active baseline first and use this module only when a host
+  project explicitly opts into Aqua-like styling.
+- Do not move new baseline decisions here.
