The blink was every poll re-running each card's entrance animation via innerHTML churn. Now cards are created ONCE and PATCHED in place (data-st attribute swaps, progress width glides over a 1.4s transition, meta only rewrites when its text changes), so nothing re-animates on a tick — the music-downloads smoothness. Also: adaptive polling (1.5s while active, 6s idle), border/pill colours TRANSITION on status change, downloading cards get an accent tint + glow, a relative 'started Xs ago', and the % moved inline. Balance clean.
