  /* Image node (editor/nodes/image.js) — same rounded/bordered treatment as

     (editor-image-frame) inside the full-width figure; the FRAME's own
     width (set inline by the node view, as a "%" string) is what actually
     resizes — never the img's. The img is always width:100% of the frame,
     height:auto, so its intrinsic aspect ratio is preserved. This split
     matters: the frame is a flex item of .editor-image (a definite-width
     container — the 42rem text column), so a percentage on the FRAME always
     resolves against that real width, at any alignment. A percentage on the
     IMG instead, with the frame shrink-to-fit around it, is a circular
     sizing constraint — collapses toward the intrinsic size, invisible
     left-aligned (the figure's full width was still there to fall back on)
