    The image catalog. Each entry references a URL (https or oras)
    the live env flashes from. bty-web doesn't host image bytes,
    and since v0.66.0 doesn't hold the catalog either -- withcache
    is the single source of truth for both bytes and manifest, and
    the <em>Add image</em> form pushes entries into withcache's
    catalog API. The <em>Warm</em> column and per-row
    <em>Pre-warm</em> action drive nbdmux's ramboot warm pipeline;
    a machine bound to a ref in ramboot mode boots as soon as its
    row shows <em>ready</em>.
