Thanks for this enhancement.
I tested the changes, and they look good, improving the vertical alignment of the font previews. I also left a small comment about the convenience of adding the transition to the image previews. However, that can be added in a follow-up because that addition was not the original purpose of this PR, so I'm approving it.

We probably need to include the transition into the demo-image class, too, to apply the same transition when the font has and lacks an image preview.

Yep consistency would be nice. Unrelated to the scope of this PR though.

display: blockon the preview image to remove native descender space.reduce-motionscss mixin.Note:
A pixel-perfect vertical alignment isn't really possible because the font preview image isn't consistent. even after improving the CSS and removing the native image descender space, the actual font preview within the image has a different size and, more importantly, it may be not vertically centered within the image. A couple images to better illustrate:
Even though the two images have the same height, the actual preview is placed differently within the image 'canvas', which is actually the viewport of the SVG image. See for example https://s.w.org/images/fonts/17.6/previews/aldrich/aldrich.svg
Maybe, the SVG metrics could be improved but this is out of the scope of this PR.
Also, trying to adjust the image size to a 'magic number' doesn't make much sense as the font previews will render fonts with different metrics anyways. See for example the screenshot below: all the font preview images do have the same height but the actual visible height of the previewed font is always different because the font metrics are different:
