// Railway kills a cron container at 10 minutes, so a tick has 570 s. Four
// 120 s sections (plus kill grace and preflight headroom) fit together; more
// would let a run of timeouts push later feeds out of every tick.

// failing is due on every tick, so a fixed order would let it hold the same
// slot forever; with rotation every feed leads within ceil(n / 4) ticks.
