+# Project Instructions
+
+## Package Manager Policy (RSR)
+
+- **REQUIRED**: Deno for JavaScript/TypeScript
+- **FORBIDDEN**: npm, npx, node_modules, package-lock.json
+- **FORBIDDEN**: bun (unless Deno is technically impossible)
+
+When asked to add npm packages, use Deno alternatives:
+- `npm install X` &rarr; Add to import_map.json or use npm: specifier
+- `npm run X` &rarr; `deno task X`
