Both loaders now stream their manga grid instead of blocking on it: the cheap
header renders immediately (and still handles 404/401 in the loader) while a
MangaGridSkeleton stands in until the grid resolves, then swaps in without a
layout shift. Collection detail seeds its optimistic-removal state from the
stream via a guarded effect.
