// Regression coverage for the race day Schedule panel (Event Manager's "Schedule" tab).
// buildEventSchedule's cascading-time math and the getSessionSortWeight ordering bug it
// exposed are already covered at the unit level (race_timing_logic.test.js) - this file
// exercises the UI wiring on top of it: the form actually persists scheduleStartAt/
// scheduleGapMin onto event.raceConfig (previously silently dropped by normalizeEvent's
// field allowlist), the table renders sessions in running order (not seed order), a
// session that started late shows the Delayed badge, and Clear removes only the start
// time, not the configured gap.
