confidential documents tips

🔒

A diagonal "CONFIDENTIAL" at ~20% opacity reads clearly without obscuring the text.

🎨

Red conveys sensitivity; gray is subtler for internal docs.

📄

The watermark is applied to all pages so no page can be shared "clean".

🔒

Sensitive files are watermarked in your browser — never uploaded.
