Capture: - Preserve real asset extensions (.lottie no longer truncated); extract the default animation JSON from dotLottie ZIP containers at materialization (minimal built-in ZIP reader, no new deps) - Reset scroll + settle before every viewport snapshot so scroll-linked styles can't bake into captured computed values - Marquee detection now requires content overflow (>1.35x), sustained velocity across separated windows, scroll independence (jiggle test), and genuine content repetition — kills scroll-settle-lerp false positives - Sizing probe trusts authored explicit heights (px/vh/calc) over circular parent/child reflow verdicts, fixing dropped 100vh heroes Normalize/generate: - Canonicalize identity transforms to "none" per viewport; emit explicit transform resets across bands when any band has a real transform - DittoLottie keeps the captured placeholder until DOMLoaded; failed loads no longer blank the container - mx-auto only for true auto-margin centering; literal per-band margins are preserved (fixes full-bleed regressions) - Spacing-scale snap tightened to 0.25px (3.5px stays p-[3.5px]); emit whitespace-nowrap for wrap-vulnerable single-line text leaves - Grid recipes no longer override captured track counts or column spans; responsive re-flow plans apply only when geometry agrees Quality scoring: - Rewritten 6-dimension rubric (payload, decomposition, duplication, semantics, hygiene, runtime) with catastrophe caps and per-dimension reporting; thresholds are documented calibration guides 218 tests pass (74 new), typecheck clean.
