- Consent API (/api/consent) with SQLite + IP hashing
- Privacy Policy (Thai) - PDPA Section 36 compliant
- Terms & Conditions (Thai) - 9 standard clauses

+import { WebSocket } from "@libsql/isomorphic-ws";
+
+const ws = new WebSocket("ws://localhost:8080");
+ws.onopen = (event) => {
+    ws.send("Hello");
+};
+ws.onmessage = (event) => {
+    console.log(event.data);
+    ws.close();
+};
+```
