Chrome does not allow WAAPI clip-path animations on ::view-transition-new
when animation:none !important is set via CSS. This caused dark→light
transitions to have no visible animation.
Replace with opacity:1 !important to neutralize the UA fade-in/out
animations: the UA animations still 'run' but cannot change opacity
because !important author declarations override CSS animation values.
WAAPI clip-path is no longer blocked.
