/**
 * Confirms the keyboard-row chip carries WHAT it will fill. Users must be
 * able to tell a creds-fill chip from a TOTP-fill chip at a glance — same
 * labels on both pages was a real user-visible gap (logged 2026-08-05).
 *
 * The fix routes the OTP-only fill path through a separate FillMode so the
 * chip title carries the actual TOTP code instead of the entry title.
