+### basePath & Reverse Proxy
+
+The app is deployed behind a reverse proxy at `/studio` path:
+- `next.config.js` sets `basePath: '/studio'`
+- All pages and API routes are served under `/studio/...`
+
+**Critical gotchas**:
+- **Next.js strips basePath from `request.url` in route handlers** — Better Auth's `basePath` must be `/api/auth` (without `/studio`), not `/studio/api/auth`
+- **`BETTER_AUTH_URL` must NOT contain a path** (just the origin like `http://localhost:3001`) — Better Auth's `withPath()` silently ignores the `basePath` config if the URL already has a path component
+- **HTTPS production adds `__Secure-` cookie prefix** — middleware must check both `better-auth.session_token` and `__Secure-better-auth.session_token`
+- **`router.push()` auto-prepends basePath** — never manually add `/studio` to paths used in client-side navigation or callbackUrl params
+- **`request.nextUrl.pathname` in middleware excludes basePath** — e.g., `/levels` not `/studio/levels`
+- Prisma requires `binaryTargets = ["native", "rhel-openssl-3.0.x"]` for cross-platform deployment (macOS dev → Linux server)
+
+### Deployment
+
+- **Server**: `root@119.91.211.52` at `/root/apps/meme-studio`
+- **Process Manager**: PM2 (`ecosystem.config.js`)
+- **Script**: `./deploy.sh` — builds locally, rsyncs files (excluding node_modules), installs deps on server, restarts PM2
+- **Standalone output**: `next.config.js` sets `output: 'standalone'`
+- Server uses `npm install --production` + `npx prisma generate` (prisma is a devDependency)
