+# Project Instructions
+
+## ⚠️ CONVERSION NEEDED: npm → Deno
+
+This repo currently uses npm but needs to be converted to Deno.
+
+### DO NOT:
+- Run `npm install`
+- Add new npm dependencies
+- Create package-lock.json
+
+### INSTEAD:
+- Use `deno task` for scripts
+- Use npm: specifiers for dependencies (e.g., `import X from "npm:package"`)
+- Create deno.json instead of package.json
+
+### Conversion Steps:
+1. Analyze package.json dependencies
+2. Create deno.json with equivalent imports/tasks
+3. Update source files to use Deno imports
+4. Remove package.json and package-lock.json
+5. Test with `deno check` and `deno test`
+
+## Package Manager Policy (RSR)
+
+- **REQUIRED**: Deno for JavaScript/TypeScript
+- **FORBIDDEN**: npm, npx, node_modules (after conversion)
+- **FALLBACK**: Bun only if Deno is impossible
