// (only while status == Downloading), blends in a moving cosine-bell
// highlight -- same trick as the splash logo's sweep -- and switches to the
// fixed purple ramp ProgressBar.tsx's animated case uses, ignoring `base`,
// matching the original 1:1 (every animated row is a downloading row, which
