/**
 * RIDE THE LINE (plan item E1, 2026-10-14; dreadwoods-backend/PLAN_1_TO_40.md section 4.2, early-game program track T12).
 * Three quests on the Western Line's four existing stops (circuit v2 is frozen: no new stop, leg or dwell), levels 5-25:
 *
 * 1. TICKETS, PLEASE (Halt Master Borrin Ashbeard, the Forge Halt): carry the new timetable round the loop, one halt master at a
 *    time. Untimed; it teaches the circuit.
 * 2. COAL FOR THE LINE (Borrin): charcoal from the Charcoal Yard's mounds for the boilers, and the Hold's receipt for it.
 * 3. THE NIGHT MAIL (Borrin): the same loop against a wall-clock (the story engine's `clock`): a satchel for every stop, back at
 *    the Forge Halt inside the time. Announcements are the countdown. Run out of time and the run is lost; the giver offers it again.
 *
 * The satchel is the quest's state, not an item (no new item kind, nothing for the client to register). Dying does not cancel a
 * run: the clock keeps going and the stops are still there. EVERY NUMBER HERE (levels, times, rewards) IS A PLACEHOLDER for the
 * balance pass (balance is last, PLAN_1_TO_40.md).

 * The Night Mail's clock, set from the real timetable (B-139, 2026-10-14). The first version (11 minutes: one 485 s lap and one
 * missed train) was missed by about a minute on every lap by a rider who waited at the platforms, because a stop's doors shut 5 s
 * before the train leaves (Lantern Wake's whole dwell is 30 s, so only 25 s to step off, find the halt master and step back on)
 * and the next train is a slot (cycle / trains, ~162 s) behind. `nightMailRideMs` below replays a rider against the timetable:
 * a perfect rider (20 s at each stop) needs at most ~627 s whatever second they accept at, and a rider who misses the train
 * at Lantern Wake and again at the Hold (30 s at each stop: the common case) needs at most ~950 s. 16 minutes covers both, with
 * 90 s or more spare for the perfect rider at the 4th stop. A test pins it against the real circuit, so a new circuit fails it.
 *
 * Circuit version 3 (2026-10-18, the faster train: 333 s lap, ~111 s slot) re-set it: the perfect rider needs at most ~423 s and
 * the rider who misses two trains at most ~645 s, so 12 minutes keeps the 90 s spare for the first and leaves the second 75 s.
