+/**
+ * Customer rule "auto-send invoice on the 3rd business day each month" (TRU-70 / DRIFT 9).
+ *
+ * The toggle lives in the existing `customer_attributes` table under the
+ * `autoSendInvoiceThirdBusinessDay` attribute. A daily cron task delegates to
+ * {@see autoSendInvoicesThirdBusinessDay()} which is a no-op on every day
+ * except the 3rd business day of the month, where it auto-queues ready
+ * collected invoices for the opted-in customers.
+ *
+ * "Business day" is computed against a locale-aware weekend (default
+ * Saturday + Sunday). Public Danish holidays are supported via a small
+ * override hook so the unit tests can pin the result without depending on
+ * the wall clock.
