The Pill overlay preset was the only one of the five to carry
`backdrop-blur-sm` (backdrop-filter: blur(4px)) on its badge class.
Each enabled badge renders its own element, so a typical library grid
produces hundreds of backdrop-filter layers the browser must re-sample
and blur on every repaint — including every scroll frame, since the
poster art behind each badge moves while scrolling. This caused severe
scroll/interaction jank, most visibly on Chrome on Windows.
The blur is also effectively invisible: the Pill background is already
rgba(20,20,30,0.7) (70% opaque), so removing it has no meaningful visual
impact while eliminating the per-frame GPU cost. The other four presets
are unaffected.
