+# Gitea to Cloudflare Pages — Linear Void
+
+## Goal
+
+Deploy the Linear Void frontend (Vite + TypeScript SPA) from Gitea to Cloudflare Pages using Gitea Actions.
+
+## Prerequisites
+
+1. **Cloudflare Pages project** created (Dashboard → Workers & Pages → Create → Pages), see [Cloudflare Pages Setup](./cloudflare-pages-setup.md).
+2. **Project name**: note the exact name (e.g., `linearvoid`).
+3. **API token** with Pages permissions:
+   - Create at <https://dash.cloudflare.com/profile/api-tokens>
+   - Permission: `Account → Cloudflare Pages → Edit`
+   - Store in Gitea → Settings → Secrets as `CLOUDFLARE_API_TOKEN`
+4. **Account ID** from Cloudflare dashboard overview → store as `CLOUDFLARE_ACCOUNT_ID`
+
+## Project-specific values
+
+| Setting            | Value                                                      |
+| ------------------ | ---------------------------------------------------------- |
+| Framework          | Vite + TypeScript                                          |
+| Build command      | `cd frontend && npm install && npm run build`              |
+| Output directory   | `frontend/dist`                                            |
+| Node version       | 20                                                         |
+| Multi-page entries | `index.html`, `admin/index.html`, `admin/login/index.html` |
+
+## Gitea Actions workflow
+
+Create `.gitea/workflows/pages-deploy.yml`:
+
+```yaml
+name: Deploy to Cloudflare Pages
+
+on:
+  push:
+    branches: ["main"]
+  workflow_dispatch: {}
+
+jobs:
+  deploy:
+    runs-on: ubuntu-latest
+    steps:
+      - name: Checkout
+        uses: actions/checkout@v4
+
+      - name: Setup Node
+        uses: actions/setup-node@v4
+        with:
+          node-version: 20
+
+      - name: Install dependencies
+        run: cd frontend && npm ci
+
+      - name: Build
+        run: cd frontend && npm run build
+
+      - name: Deploy to Cloudflare Pages
+        uses: cloudflare/pages-action@v1
+        with:
+          apiToken: ${{ secrets.CLOUDFLARE_API_TOKEN }}
+          accountId: ${{ secrets.CLOUDFLARE_ACCOUNT_ID }}
+          projectName: linearvoid
+          directory: frontend/dist
+          gitHubToken: ${{ secrets.GITEA_TOKEN }}
+```
+
+If the `cloudflare/pages-action@v1` action is unavailable from Gitea, use the direct API approach:
+
+```yaml
+- name: Create deployment artifact
+  run: tar -czf site.tgz -C frontend/dist .
+
+- name: Deploy to Cloudflare Pages
+  env:
+    CLOUDFLARE_API_TOKEN: ${{ secrets.CLOUDFLARE_API_TOKEN }}
+    CLOUDFLARE_ACCOUNT_ID: ${{ secrets.CLOUDFLARE_ACCOUNT_ID }}
+  run: |
+    curl -sS -X POST \
+      "https://api.cloudflare.com/client/v4/accounts/${CLOUDFLARE_ACCOUNT_ID}/pages/projects/linearvoid/deployments" \
+      -H "Authorization: Bearer ${CLOUDFLARE_API_TOKEN}" \
+      -H "Content-Type: application/octet-stream" \
+      --data-binary @site.tgz
+```
+
+## Secrets to add in Gitea
+
+| Secret                  | Value                                |
+| ----------------------- | ------------------------------------ |
+| `CLOUDFLARE_API_TOKEN`  | API token with Pages:Edit permission |
+| `CLOUDFLARE_ACCOUNT_ID` | Cloudflare account ID from dashboard |
+
+## Verify deployment
+
+1. Push to `main` or trigger manually from Gitea Actions.
+2. Check **Gitea Actions** → job logs for the deploy step.
+3. Check **Cloudflare Pages** → Deployments for the new deployment.
+4. Visit the `.pages.dev` preview URL, then promote to `linearvoid.tv` when ready.
+
+## Notes
+
+- The existing `ci.yml` already builds the frontend; the Pages deploy workflow is additive and independent.
+- Multi-page SPA (`vite.config.ts`) produces three entry points — Cloudflare Pages serves them correctly.
+- For SPA fallback routing, add a `frontend/public/_redirects` file with `/* /index.html 200` before building.
+- If deployments fail with 403, verify the API token has `Account → Cloudflare Pages → Edit` permission.
