            ### Downloads
            - **ISO** — Boot from CD/USB, ideal for testing
            - **Disk Image** — Raw disk with A/B partitions + GRUB
            - **Binaries** — Standalone cloud-init and update agent

            ### Verify
            ```
            sha256sum -c SHA256SUMS
            ```

            ### Quick Start
            ```bash
            # Boot in QEMU
            qemu-system-x86_64 -m 1024 -smp 2 -enable-kvm \
              -cdrom kubesolo-os-${{ steps.version.outputs.version }}.iso \
