Clip-path reveals & curtains
Pure clip-path wipes: the element's box is unclipped from a chosen edge. No opacity is involved, making them ideal for media and containers that must stay fully opaque while revealing.
Edge reveals
clip-reveal-up
clip-reveal-down
clip-reveal-left
clip-reveal-right
The bare .clip-reveal class is a legacy alias for .clip-reveal-up.
Curtains
Open outward from the centre - a slit widens until the whole box is shown.
curtain-horizontal
curtain-vertical
These entries are registered with text: false, so no .spawn-text-* SplitText variant is generated for them - splitting media boxes would be pointless.
