- Users: one card per person on every screen size, status and MFA as
icon plus word, server reasons (e.g. "more rights than you") shown.
- Audit log: names instead of user ids, area as a choice instead of a
free-text type, optional record id, filter reset, cards instead of a
5-column table, empty and error states with a next step.

- Per-account lockout: five failed attempts (password, MFA code or a
step-up confirmation) lock the account for 15 minutes, on top of the
per-IP throttle - guesses spread over many addresses no longer help.
- A TOTP code is accepted once: the time step is stored and that step or
any earlier one is refused (also between two concurrent requests).
- Login runs bcrypt on every path and answers unknown email, wrong
password, deactivated and locked accounts with the same message; failed
logins for unknown emails no longer write attacker-chosen text into the
audit log.
- Turning MFA off needs password and a current code; turning it on needs
the password. Both end all other sessions.
- New audit action ACCOUNT_LOCKED.
