Dynamic watermarking, explained for non-engineers

Dynamic watermarking renders the viewer's email, IP fingerprint, and timestamp diagonally across each slide. Useful properties:

- The watermark is per-visitor, so a leaked screenshot identifies the leaker. - For downloads, we re-stamp the PDF server-side, then bake an invisible fingerprint into the PDF metadata.

Things watermarking does not do: prevent screenshots. No browser tech does. The honest framing is deterrence + traceability, paired with a kill-switch you can pull on suspicion.
