/**
 * The Blackwake Gatehouse at the north end of the Sundered Span. Since 2026-10-08 (James: "why are pirates guarding a stone
 * bridge?") it is the RUINED OPEN ARCH `spanruin` that ends the bridge at the Landing: no gate, no guards, open to everyone.
 * Its id, corridor and the posts below are kept so saves and old code keep working; nothing shuts the corridor any more.
 * Before that: the shared world kept it shut. Each character carries
 * `blackwakeGatePosts`, a 2-bit mask of the two gate Lookouts they have defeated (1 west, 2 east); at 3 the gate is open
 * for that character alone: their client is sent the open style and their own walks may cross the corridor.
 *
 * Both posts stand NORTH of the shut gate (the original homes at 668,940 and 684,940 were behind it, so a locked
 * player could not reach them at all): the nearest safe tiles on the bridge approach.
