Wave Animation
Tilts and rises in a slow, continuous swell.
Opens with this animation loaded. Nothing is uploaded — the scene travels in the link.

}Why it is built this way
Rotation and vertical travel on slightly different rhythms, which is what keeps a loop from looking mechanical. Two properties on the same timing would read as a single rigid movement.
What it animates
2 properties across 1 CSS declaration. The bar shows when each one is moving.
transformtransformWhat it costs to run
Rotate and y is 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 1.80s across 7 keyframe stops, with every property moving over the same window.
One curve throughout: Ease In Out on a text. 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 — rotate and y move over 1.80s 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.
