Hiding photos left the viewer showing low-res thumbnails: the filter change evicted previews without reloading them, a full-library thumbnail sweep starved preview decoding, every culling keypress cancelled the preview loader mid-flight, and the preview cache had no memory budget so the system purged it at random. Previews now survive all four. Photos within a group are also ordered chronologically rather than by focus quality, which reads more naturally while culling. The quality score still drives the best-in-group badge. 💘 Generated with Crush Assisted-by: Crush:claude-opus-5
