	 * `$conditions_groups` (effectively arbitrary — see spec 034 SC-003).
	 *
	 * The tie itself is now settled by active flag, then recency, then ID. Lowest-ID
	 * alone meant the OLDEST template won, so a newly imported header could never
	 * displace the one a previous import left behind. Still deterministic — the
	 * property SC-003 actually cares about — just no longer ordered by age ascending.
	 *
