Changelog

v0.1.1

Sibling layout caches now refresh on every animation frame during a size-collapsing exit, and are nulled when the element is finally removed. Previously, the post-removal relayout would FLIP each neighbor by the full reflow distance, snapping them back to their pre-exit positions and animating up again.

Special-case collapse for <tr> exits. Because display: table-row derives its height from the tallest cell rather than its own CSS height, each cell's padding, font-size, and line-height are now animated to zero alongside the row's exit. The row's intrinsic height shrinks with the animation while the table layout stays intact.
fontSize and lineHeight added to PX_PROPS so the keyframe builder emits them with a px unit instead of as bare numbers (which WAAPI silently ignores).

Initial release.

<.animated> component — one component for enter, exit, layout (FLIP), and size animations.
Tween transitions with phase-aware easing defaults (ease-out on enter, ease-in-out on exit and layout).
Spring transitions backed by a numerical ODE solver — overshoot and damping behave physically.
Smart defaults: opacity fade by default, auto-resolved targets when only initial is given, padding/margin/border collapse on size animations.
Inferred mid-life animations — position and size changes animate automatically; opt out per element with disable: [:position, :size].
Server-driven exits via phx-remove, with cascading-order preservation and sliding-window stack handling out of the box.
