+## Convention: Frontend Design Token Sources
+
+**What**: Runtime visual tokens use the sources that are actually consumed by
+the frontend build. CSS custom properties live in
+`client/src/design/theme.css`, which is imported by `client/src/index.css`;
+Tailwind theme values live in `client/tailwind.config.js`.
+
+**Contracts**:
+
+- Do not maintain a parallel TypeScript token object when no component, build
+  plugin, generator or synchronization test consumes it.
+- Before adding, replacing or deleting a token source, search direct imports,
+  type-only imports, `import.meta.glob`, generators, copy/sync scripts and
+  build configuration.
+- Historical Issue CSV and archived Trellis references describe their original
+  delivery state; they are not current runtime consumers and must not be
+  rewritten merely because a source file is later removed.
+- If typed tokens become necessary later, introduce them with explicit runtime
+  consumers or a generated single-source contract plus a drift regression
+  test; do not manually duplicate CSS values.
+
+**Why**: Unconsumed token mirrors drift from the CSS that actually renders the
+product, creating a misleading second fact source and unnecessary maintenance.
+
+**Tests Required**:
+
+- Exact consumer search for the changed token module or symbol.
+- `cd client && npm run typecheck`
+- `cd client && npm run build`
