Dialog panels animated in with
transform: scale(0.95 → 1). Scaling re-samples the 1px dividers (header/tabs borders) at fractional thickness during the animation, then snaps them crisp at the end — a visible flicker, far more noticeable in light mode where dividers (zinc-200on white) have high contrast than in dark (zinc-800onzinc-900).Fix: replace the scale entrance with
translateY(8px → 0)+ opacity (renamedscale-in→pop-in). Translation is composited without re-rasterizing, so borders stay crisp throughout. Same 0.15s entrance feel.
