+Shared-template drift enforcement is registry-backed:
+`frontend-modern/scripts/shared-template-registry.json` is the canonical list of
+standardized repeated affordances, required consumers, and forbidden local
+patterns, while `frontend-modern/scripts/shared-template-audit.mjs` enforces
+that registry. Future repeated-affordance migrations must add or extend a
+registry rule as part of the same change that extracts or adopts the shared
+primitive.
+Platform table frames are one of those registry-backed templates.
+`frontend-modern/src/features/platformPage/sharedPlatformPage.tsx` owns
+`PlatformTableShell`, including the canonical table card, header row, and body
+divide styling. New platform tables must start from `PlatformTableShell`; the
+legacy table-frame allowlist in `shared-template-registry.json` is migration
+debt, not precedent, and must shrink as existing tables are moved onto the
+shared shell.
 The shared help icon now follows that same owner split.
 `frontend-modern/src/components/shared/HelpIcon.tsx` stays the render shell,
 `frontend-modern/src/components/shared/useHelpIconState.ts` owns open state,
