● READY — Vault empty, system unlocked
Mode:

1) Send a confidential document
Demo PIN for the recipient: 2468 (simulated, shown for demo only)

Threat-model honesty: this interface does not redisplay shredded sections. It cannot stop a person photographing paper, and software alone cannot prove physical destruction — in real hardware that needs sensors. Lock state is saved in this browser, so a refresh does NOT clear a RED lock.
