//  WLEquipGui.RefLayout.cs — PD 레퍼런스 레이아웃(#881 · 2026-10-16)
//
//  PD 원문: 「장비 아이템에 텍스트가 너무 많아. 첨부한 레퍼런스 게임과 같이 장비 UI 팝업의 레이아웃을 수정해줘」
//          + 「인벤토리 화면도 예시 이미지와 같이 레이아웃을 개선하도록 해.」
//  - 장비 상세 팝업 V2: 등급 리본 · 제목 띠 · 아이콘 + 「레벨: n/max」 · 능력치(+다음 레벨 증가분) + 합성 · 강등 작은 버튼 · 짧은 설명 ·
//    「등급 스킬」 목록(등급 색 점 · 잠긴 등급 = 자물쇠 + 흐림 · 마지막 줄 = 시너지) · 비용 줄 · 버튼 3(장비 · 레벨업 · 일괄 레벨업).
//    예전 긴 글(FR 옵션 · 계산식 · 설명 문단)은 넣지 않는다.
//  - 인벤토리 머리줄: 부위 탭 대신 「정렬 · 나의 장비 · 합성」(부위 거르기 = 빈 슬롯 누르기 · 제목 누르면 전체).
//  치수 · 색 · 글자 · 아이콘 = Resources/WL/WLEquipGui.json itemPopup · hub(C45).
