// The Frontier — the second content pack for The Ladder.
//
// Cold Fork, a freight town at the end of a stage line. You are a hired hand
// in Vane & Co.'s yard; the town has a marshal who is tired and a road that is
// not safe. Two rungs, the same as Corporate Ladder, and not one line of
// engine code between them.
//
// This pack exists to prove the split holds. Everything that makes it a
// different game from Corporate Ladder is in this directory: a four-day cycle
// instead of a week, money that arrives from work rather than from a wage,
// relationship stats named for a place where being owed a favour matters more
// than being liked, and a skill pair of nerve and trade.
