How xxxhaoxxx/czr-hook works

CZR-Hook is an Android Unity game overlay described as a drawing project. Its visible workflow starts when the native library loads, initializes in a background thread, reads Unity/IL2CPP game objects, and draws item information and tracers through ImGui. The excerpts show the IL2CPP lookup layer and xDL’s Android ELF/linker support, but not the full initialization or hook setup; dashed links mark those uncertain runtime connections. The README provides no further feature inventory.
