// 로비 codeblock 2종 emit (맵/엔티티 부착은 tools/map/gen-lobby-map.mjs 소관):
//  · LobbyNpc      — NPC 엔티티에 부착. 근접 폴링→머리위 마크 토글, TouchEvent(클릭)/UpArrow(근접)→Interact→컨트롤러 호출.
//  · LobbyMobility — 로비 맵 루트에 부착. 진입 시 플레이어 이동 잠금 해제(정찰 확정: WalkAcceleration이 진짜 레버).
// 공격 키(LeftControl) 바인딩은 SlayDeckController(/common, 1회 등록·로비 가드)에서 처리 — 여기 두지 않음.
// 정찰: 이동에는 RigidbodyComponent.WalkAcceleration(가속)과 MovementComponent.InputSpeed(속도)가
// 둘 다 양수여야 함 — freeze-turn-player가 둘 다 0으로 만들었으므로 둘 다 복원해야 걷는다(실측 확인).
// 값은 freeze가 건드리지 않은 intact RigidbodyComponent.WalkSpeed(1.4)/WalkJump(1.23) = 기본값에 맞춤.
// (실측: InputSpeed 1.4→보행 ~2.5u/s, JumpForce 1.23→점프 상승 1.79u. 이전 5/5는 ~9u/s·상승 14u로 과함.)
