+The active frontend implementation rules live in
+`../hyb-oa/frontend-react-vite-design.md`. Product experience facts remain in
 `docs/产品设计规则.md`. Visual and interaction design authority comes from the
 installed `frontend-design` skill.

+This directory intentionally contains no separate frontend guideline files. The
+old default scaffold files were removed because placeholder specs are noise for

-## Language
+## Rule
 
-Project rules are Chinese-first where they are user-facing. Short English files
-generated by Trellis may remain when they are tool-facing scaffolding.
+Add a new frontend spec file only when a later Trellis task discovers concrete,
+source-backed frontend conventions that do not belong in the project-level
+frontend/design spec.
