//   ■ Safe Area 를 패널 **2개**로 나누는 이유 (실측 근거 · 완료보고 ⓒ)
//     NewGameUI 캔버스 직속 12레이어에는 Canvas/sortingOrder 가 하나도 없다(실측: 5레이어 전부 컴포넌트 1~2개,
//     Canvas 0개) → **그리는 순서 = 형제 순서**다. 대상 5레이어는 원본에서
//        Common(4) · LobbyUIs(5) < IngameUIs(6) · FarmUIs(7) < MessageInfo(8) · Center(9) · PopupMgr(10) < TestMapUIMgr(11)
//     로 **IngameUIs/FarmUIs 를 사이에 끼고 앞뒤로 갈라져 있다**. 5개를 패널 하나에 몰면 앞뒤 관계가 뒤집힌다
//     (로비 UI 가 인게임 UI 위로 올라오거나, 팝업이 인게임 UI 아래로 내려간다).
//     그래서 Back(Common·LobbyUIs) / Front(MessageInfo·Center·PopupMgr) 두 패널을 원래 자리에 끼워
//     **평탄화하면 원본과 완전히 같은 순서**가 되게 했다.
