-
-            **Why this matters:** Broken model download links will prevent users from using the workflows properly. All URLs in \`properties.models[].url\` fields and MarkdownNote/Note widgets must be valid and accessible.

-
-            ### Common Issues:
-
-            1. **404 Not Found**: The file or page doesn't exist
-               - Verify the URL is correct
-               - Check if the file was moved or renamed
-               - Update to the correct URL
-
-            2. **Timeout**: Server didn't respond in time
-               - Verify the URL is correct
-               - Check if the server is temporarily down
-               - Try accessing the URL manually
-
-            3. **Connection Failed**: Unable to reach the server
-               - Verify the domain exists
-               - Check if the repository/file was deleted
-
-            ### How to Fix:
-
-            1. **For model URLs in \`properties.models[].url\`:**
-               - Update the URL to a valid download link
-               - Ensure the model file is still available
-               - Test the URL manually before committing
-
-            2. **For links in MarkdownNote/Note widgets:**
-               - Update or remove broken documentation links
-               - Ensure all referenced resources are accessible
-
-            ### Testing Links Locally:
-
-            \`\`\`bash
-            # Extract and check links
-            python3 scripts/check_links.py extract

-          Your template has thumbnail configuration issues that need to be resolved.

-          2. **Incomplete dual thumbnails**: Templates with \`thumbnailVariant: "compareSlider"\` or \`"hoverDissolve"\` need both \`-1\` and \`-2\` thumbnail files
-          3. **Check file naming**: Thumbnail files should be named \`{template_name}-{number}.{extension}\`
