gicha crayon’s KTX seat alarm

Field notes

The interface combines station, date, train-type, time-range, and seat-class filters, then keeps checking while the user leaves the tab open. The page states that same-day journeys may be checked at intervals of at least 30 seconds, while more distant dates may take up to 10 minutes depending on usage. Operational limits are explicit: each alert lasts two hours, and one IP may register up to five alerts per hour.
