Aesel now treats .svg as a picture, and the Slab card stages it as artifact.svg so WebKit draws it (it never sniffs SVG), sizes it from width/height or viewBox, and checks it as text rather than through NSImage. Loaded as an img, its CSS and SMIL animation play while no script runs. Bumps Aesel to 0.8.21; the card probe now includes SoundSketch so it compiles again.
