+/**
+ * Add the daily booking-desk close hour.
+ *
+ * The import booking window used to reopen only within the same EAT calendar day
+ * as its close; a cycle whose reopen crossed midnight died at CLOSED_FOR_DAY with
+ * capacity still free. The window now runs a daily office range [openHour,
+ * closeHour): a not-yet-full train pauses at closeHour and resumes the next
+ * morning at openHour, every day until it fills or departs. openHour === closeHour
+ * means a 24-hour desk.
+ *
+ * `window_close_hour` on the global-rules singleton is the live config; the
+ * matching `rule_window_close_hour` snapshot on each schedule freezes it at
+ * creation so the batch board keeps drawing the window the customer was shown.
+ * Both default/backfill to 17:00 (5 PM), the previous implicit office close.
