// words. While the flag is set, lock-on-close and auto-lock are suppressed
// — locking would discard the derived key required to re-show the words on
// reopen, and the words cannot be recovered without it.

// Lives in chrome.storage.session (RAM-only; cleared on browser restart).
// If the browser closes before confirmation, the flag and the in-memory key
// are both lost together — the recovery words become unreachable, which is
// the same outcome the user would face with any unconfirmed-but-unsaved
// secret.
