Without funnel data, variant-winner conclusions have insufficient evidence.
Check empty, error, retry, and draft-persistence branches during static review.
Check rendered hierarchy, dominant control, spacing, contrast, alignment, truncation, overflow, and responsive breakpoints during visual review.
Check user-journey progression, in-progress and locked states, forced error or empty states, focus order, and keyboard reachability during dynamic review.
Capture CLS, LCP, INP, and long-task values only through dynamic review.
