/* Baby avatars

   The artwork is one sprite, `assets/avatars.svg`, pulled in with `<use>`, so
   what differs per gender here is the palette alone. Custom properties inherit
   into the `<use>` shadow tree, which is why setting them on the outer `<svg>`
   recolours the referenced symbol — and why the sprite can spell the same three
   tokens in all three symbols. The literal fallbacks in that file are what paint
   when this sheet is missing: without them a failed stylesheet would leave three
   invisible boxes where the avatars should be. */
