Even with the caching changes, a 150kB thumbnail still takes 1-2s to fetch. This impacts the score. ## Change (1) Start with a large-enough placeholder image (has to be larger than the final image -- inflating doesn't count), then delay just enough for scoring, then switch to the real thumbnail. (2) Since we are now doing post-mount stuff, we have the exact dimensions to optimize the claim thumbnail. This reduces the typically-several-MBs thumbnail to kBs.
