// Entrance / exit animations (block "Animations" panel, in the Styles tab).
//
// Each animation has an explicit "in" (hidden -> visible) and "out"
// (visible -> hidden) @keyframes pair. `animation-direction: reverse` is
// intentionally NOT used to play the "out" keyframes backwards: combined
// with `animation-fill-mode: both` on an animation that is renamed and
// started in the same tick, some engines mis-resolve the fill state, so the
// block jumps straight to hidden instead of fading out. assets/js/animations.js
// always arms the target animation paused first, then only ever flips
// `animation-play-state` to resume it — the same reliable mechanism for
// both directions.
