// The 传送门 (portal) of the boss / hidden-core templates (GitHub #336, PR #337 by @2321Robin): an enemy flies or walks
// into the portal and reappears on the far side. Four official routes spell the crossing as DISAPPEAR → WAIT → MOVE-to-the-exit with no APPEAR step
// (act1autochess_h07_02 route #4, act1autochess_h08_02 routes #5/#9, act2autochess_h07_05 route #6), while their twin
// routes in the same templates write it out as DISAPPEAR → WAIT → APPEAR[exit]. Taken literally, an appear-less route
// made the enemy walk its whole remaining route invisible and then leak unseen — the blue door takes the leak and the
// team never sees who or how (user report: 打 boss 时小怪进传送门后被判定进蓝门,全程隐身). normalizeRoute re-inserts
// the exit APPEAR ahead of that MOVE — at the MOVE's own target, which is exactly where the twins appear.
