On a Skeleton
The placeholder blurs out as the real row blurs in. A plain crossfade reads as a flicker; the blur is what makes it a swap. Both layers sit in one grid cell and the skeleton has the row's shape, so nothing reflows at the handover.
The class is wm wm-skeleton-swap — the first half is the marker the trigger and reduced-motion rules hook into, the second is the effect.
