v0.2.1

Performance

• The relayout pass (inferred FLIP and size animations) now skips elements far
  outside the viewport. It runs on every LiveView patch and measured every
  tracked element, so on a page with hundreds of animated elements a patch that
  changed three of them still cost tens of thousands of layout reads — twice,
  since the deferred exit removal triggers a second pass. Off-screen elements
  are now skipped, and the visibility observer reseeds their cached layout when
  they come back toward the viewport. The per-frame sibling remeasure during a
  size-collapse exit skips off-screen siblings the same way.
