 - **Images**: Referenced images must exist and be under 1MB
+- **Logos**: `imageLink.darkLogo` and `imageLink.lightLogo` are repo-relative paths to image files (e.g. `assets/images/dark-logo.png`), not external URLs. Leave as empty strings (`""`) to use the platform default.
 - **Security**: Notebooks are scanned for XSS, script injection, and credential exposure
