# DESC:  CI/CD for H100PowerManger
#        - build/test on aarch64 (QEMU emulation of arm64 Ubuntu 20.04)
#        - deploy the cross-built binary to the RK3588 board
#        Self-contained (no external actions). The runner is an Alpine
#        container with the host Docker socket mounted; we install the
#        docker CLI at runtime.
