// This file makes the secret-bearing domain types safe to log by construction.
// User.PasswordHash / User.TOTPSecret and Session.TokenHash are json:"-", but
// that only guards JSON responses — slog renders struct fields regardless. By
// implementing slog.LogValuer, logging a *db.User or *db.Session (e.g.
// slog.Info("x", "user", user)) never emits the credential. Secret fields are
// omitted entirely; the useful identifying fields stay visible.

// LogValue omits PasswordHash and TOTPSecret. It exposes whether TOTP is
// enabled (not the secret) since that is often what a log line needs.
