The drawing card now loads any <image> hrefs its SVG references into
ui.Images before painting (loadDrawingImages, decoder injectable for
tests) — the renderer and the lightbox both paint through the resolver, so
a compare card shows real images and zooms. main registers the `compare`
template with a workspace path resolver. A drawing with no images is
unaffected.
