Slide Reveal Animation
Uncovers from the bottom in one clean sweep.

}Why it is built this way
A single inset value animating to zero. The cheapest reveal in this set, and unlike a height animation it never touches layout.
What it animates
1 property across 1 CSS declaration. The bar shows when each one is moving.
clip-pathWhat it costs to run
Clip-path repaints on every frame rather than running on the compositor. There is no reflow, so this is far cheaper than animating width or height — but keep the painted area modest.
It runs for 0.80s across 2 keyframe stops, with every property moving over the same window.
One curve throughout: Ease Out on a card. Keeping a single easing across every property is what makes a multi-property animation read as one movement rather than several things happening at once.
Accessibility
Nothing here hides content — clip-path moves over 0.80s and the element is visible throughout. The exported prefers-reduced-motion guard still silences it, which matters most for the looping ones: motion that never stops is the kind that makes people feel unwell.
