//   ① ConvertLegacy : Master Stylized FX 안에서 아직 내장(Built-in) 셰이더(Particles/Standard Unlit 211 · Surface 210 · Standard 46)를 쓰는 머티리얼을 URP 로 변환.
//      동봉 MSFURP 패키지가 46장을 빠뜨린다(DizzyStar·SleepSymbol·BubbleSymbol·Spike3D 등 = 우리가 쓰는 것들). _Mode(2 Fade·4 Additive) 와 블렌드 값을 그대로 옮긴다.
//   ② Build : Prefabs/Buffs·Hit 의 원본 프리팹을 복제해 Resources/WL/Status/<name>.prefab 으로 저장(독은 보라 틴트). 원본 에셋 무수정.
