+   For any design changes, new views, or UI modifications:
+
+   ```bash
+   # Start the dev server if not already running
+   bin/dev  # Run in background
+
+   # Use Playwright to take screenshots at mobile width (320px)
+   # Navigate to relevant pages and capture before/after states
+   ```
+
+   Using Playwright MCP tools:
+   - `browser_resize` to set mobile viewport (320x568 or similar)
+   - `browser_navigate` to go to affected pages
+   - `browser_snapshot` to check page state
+   - `browser_take_screenshot` to capture images
+
+   Then upload screenshots using the imgup skill:
+   ```bash
+   # Upload to 0x0.st (recommended, no API key needed)
+   curl -F "file=@screenshot-before.png" https://0x0.st
+   curl -F "file=@screenshot-after.png" https://0x0.st
+   ```

+   Include the URLs in your PR description.
