      "<strong>Repository hygiene first.</strong> Disables the enterprise <code>pve-enterprise.sources</code> / <code>ceph.sources</code>, removes legacy repo files left over from previous PVE versions, and writes a clean <code>proxmox.sources</code> pointing at the free <em>pve-no-subscription</em> channel (matching the host's Debian codename: trixie for PVE 9, bookworm for PVE 8).",
      "<strong>Debian repos rewritten</strong> with main / updates / security, including <code>non-free-firmware</code>, so the firmware warning during upgrade goes away.",
      "<strong>Runs the official upgrade.</strong> <code>apt-get update</code> followed by <code>apt full-upgrade -y</code> (PVE 9) or <code>apt dist-upgrade -y</code> (PVE 8), both launched non-interactively with <code>--force-confdef --force-confold</code> so any configuration files you customised stay yours.",
