## What this tool does
Add an invisible text layer to scanned PDFs — Ctrl+F, copy and index work again. Visuals untouched.

## Typical user problems
- Scanned PDFs are photographs — Ctrl+F finds nothing, copy-paste is impossible, and document systems cannot index them. You need the search-and-copy ability added without changing a single pixel of the original pages.
- Your scanned contract is 30 pages of images — nobody can find clause 8.3, and DMS indexing ignores it entirely. You need a text layer under the exact same visuals.
