+# Caterium production on Timeweb Cloud App Platform
+
+Target domain: `app.caterium.ru`
+
+## Application settings
+- Repository: `pavlov346346-source/caterium-app`
+- Branch: `production`
+- Type: Frontend / HTML-CSS-JS
+- Publish directory: `public`
+- Auto deploy: enabled for the `production` branch
+
+The `production` branch is updated automatically only after the `Caterium QA` GitHub Actions workflow succeeds for a push to `main`.
+
+## Domain
+Add custom domain `app.caterium.ru` in Timeweb App Platform and use the DNS records Timeweb provides for the application. Keep Cloudflare proxy out of the production request path.
+
+## Validation after DNS/SSL is ready
+1. Open `https://app.caterium.ru` without VPN from a Russian network.
+2. Sign in to Caterium.
+3. Verify workspace loading and Supabase sync.
+4. Create and edit a test order.
+5. Open clients and catalog.
+6. Upload/view a photo.
+7. Generate/download a client proposal PDF.
+8. Install/open the PWA and verify refresh/offline shell.
+
+Do not decommission the old Cloudflare Worker until these checks pass.
