 * locked (disabled, with a "Pro" badge); when Pro is active they become
 * interactive and the Pro plugin saves their values.
 *
 * The lock state is derived from `subscrpt_pro_activated()` and injected onto
 * every field as `pro_locked`, which SettingsHelper uses for the badge and the
 * non-interactive styling.
