  "cause": "Rapid End/Home/Tab reversals raced native scrolling. A Home-only wait appeared sufficient in two diagnostic pairs but failed later repeat runs; an End-then-Home wait also had native reversal failures. The final required keyboard-fallback test instead uses a freshly published65536px fixture, settled End then native Tab, preserving focused+in-viewport assertions. This tests the requested journey without an unrelated reversal sequence. Runtime bytes never changed.",
