{# Machine Summary card body. Rendered at page load (ui_dashboard)
   and swapped live on the ``dashboard-machine`` SSE event. Lives in
   its own col in dashboard.html so it's an independent, equally-
   spaced grid column (not bundled with Images). The id lives on the
   card (not the col) so the sub-nav "Machine Summary" jump + its flash
   ring hug the card, and it survives the SSE swap (the card is what
   gets swapped in). #}
