 ## Features
 
-- **Zero Config** — No build step. Point to routes and serve.
-- **File-Based Routing** — Put route files in a folder, URL follows that structure.
-- **Context** — Body, query, params, cookies, headers, plus helpers to respond.
-- **Middleware** — Global or per path. CORS, auth, session, WebSocket.
-- **Static Files** — Serve directories with optional cache and etag.
-- **Error Handling** — Custom or default HTML/JSON error responses.
-- **Hot Reload** — Routes and templates reload automatically when files change.
-- **Worker Pool** — Offload heavy work to a pool so the server stays responsive.
-- **Frontend Optional** — Use any frontend. Deserve stays the server.
