## Summary Reduce/fix the lag on the home screen before recent book covers are rendered ## Additional Context We were previously rendering the screen in two steps, delaying the recent book covers render to avoid a lag before the screen loads. In this PR, we are now doing that only if at least one book doesn't have the cover thumbnail generated yet. If all thumbs are already generated, we load and display them right away, with no lag. --- ### AI Usage While CrossPoint doesn't have restrictions on AI tools in contributing, please be transparent about their usage as it helps set the right context for reviewers.
