Add Watermark troubleshooting

Common issues

• If text clips, reduce font size or change angle.
• If visibility is weak, increase opacity slightly.
• If results look crowded, shorten watermark text.

Recovery steps

1. Retry with a smaller sample file.
2. Refresh and run the tool again.
3. Use an alternative workflow from /tools if needed.
4. Check /status for current incidents.

What this does not protect

• Troubleshooting guidance does not guarantee recovery for damaged files.
• It does not bypass document owner restrictions when cryptography is enforced.
