//  WLFarmLook.cs — WL_FarmLook 씬의 되돌리기 스위치 (WL-816a · #816)
//
//  씬에는 **통일 룩(Toon · 텍스처 유지안)이 이미 저장돼 있다**. 이 컴포넌트는
//    · `enabled_ = 0`  → 저장해 둔 FarmingIsland 원본 머티리얼·원본 조명으로 100 % 되돌린다
//    · `mode = 2`      → 단색안 머티리얼로 갈아끼운다(비교용)
//  만 한다. 에셋(FarmingIsland 원본 머티리얼·프리팹·씬)은 **한 글자도 안 바꾼다**.
//
//  🔴 Debug.LogError / Debug.LogException 을 쓰지 않는다(813z 규칙).
