Zoom Out Animation
Shrinks away toward its centre while fading.

}Why it is built this way
The natural counterpart to a zoom entrance, and the standard way a modal closes. Scaling below about eighty percent starts to read as the element falling backwards rather than closing.
What it animates
3 properties across 2 CSS declarations. The bar shows when each one is moving.

Opacity, scale x and scale y are handled by the compositor: no layout, no repaint, and the work can run off the main thread. This is the cheap end of CSS animation, which is why it stays smooth on a slow phone where other properties will not.
It runs for 0.60s across 6 keyframe stops, with every property moving over the same window.
One curve throughout: Ease In on a plain box. 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 — opacity, scale x and scale y move over 0.60s 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.
