A controlled passphrase screen with create and unlock modes: create renders passphrase + confirmation with a minimum-length gate and composes the password-strength-bar from caller-computed strength props; unlock renders a single field with an error surface (e.g. wrong passphrase) and busy state. Submits the passphrase via onSubmit; performs no crypto and retains no passphrase. Pairs with useEncryptedVault.
