   browser's default fade to the site's own timing/easing instead
   of leaving it on the UA default. Progressive enhancement: browsers
   without support (older Safari/Firefox) just navigate normally,
   identical to before this existed. Custom properties are not
   trusted to inherit into ::view-transition pseudo-elements
   consistently across engines, so the values are the literal
   --dur-base / --ease-out numbers, not var() references.
