Unlock live mode

1. The person running RT Assist chooses one long private phrase.
2. On a new browser, you enter that same phrase once—or use one-click local unlock when the server enables it.
3. The server verifies it and gives this browser a private, HttpOnly session cookie for up to 12 hours. The phrase is not stored in browser storage.

Use the safe demo without signing in. Live transcription, saved playbooks, private context, and recaps require an unlocked workspace.
