// Regression test — Pipe Puzzle: a tile's rotation animation must keep running
// after the pointer leaves the tile (mouse-out) mid-spin.
//   node tools/regressionPipePuzzleUnhover.cjs [baseURL]
//
// Background: Phaser 3.90's `tweens.killTweensOf(target, 'prop')` no longer
// supports the prop filter — the argument is silently ignored and EVERY tween
// on the target is destroyed. PipePuzzleGame used it as
// `killTweensOf(tile, 'scaleX')` in the pointerout handler, which killed the
// in-flight rotation tween and froze the tile at a half-rotated angle.
//
// This test drives the same code path the pointerout event hits
// (`_setHover(i, false)`) while a rotation tween is live, and asserts:
//   1. the rotation tween SURVIVES the un-hover and completes to target;
//   2. the hover scale tweens are the only ones replaced;
//   3. mirror case: clicking/re-hovering mid-spin also must not kill the
//      in-flight scale tween.
//
// Completion is verified by manually ticking the tween manager
// (`tweens.tick()`), which is deterministic even when headless RAF is
// throttled. Exits non-zero on failure.
