//   - 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 (see lucy-infra
// containers/crafting-table/Dockerfile + ad-hoc install notes 2026-05-24).
