pass - measured over 10733 pixels carrying ink in either image.
These results are not meaningful. This check renders a single static frame, and nothing in a test document records which moment in time its reference image was captured at - so a correct SMIL implementation and a broken one are equally likely to mismatch. Animation behaviour is covered by dedicated unit tests instead; see ctgnz/foxglove#208 for a real measurement methodology, still to be worked out.

Difference
In the difference panel, red marks pixels that
differ beyond tolerance and grey marks matching content. The tinted band, where present, is the
<text id="revision"> legend every test carries: it renders in a fallback font this
library cannot match, so it is excluded from the comparison entirely rather than failing every test.
What this test checks
The test is passed if: At the start of the animation the innermost rectangle is filled by a yellow semitransparent color Over the course of three seconds the yellow rect smoothly animates its width and height so that at time t=3s fully fills the middle rectangle The animation then continues in the same fashion and at time t=9s fully fills the largest rectangle with blue stroke
