//                      via cargo-ndk and drops the .so files in strawApp/src/main/jniLibs/.
//   uniffiBindgen    — generates the Kotlin bindings from the freshly-built lib
//                      into strawApp/src/main/java/uniffi/strawcore/.
//
// Both depend on:
//   - cargo + rustup with the four Android targets installed
//   - cargo-ndk on PATH
//   - ANDROID_NDK_HOME pointing at an NDK with the right toolchains
// All of that lives in the crafting-table container.
