Feeds that list several groups previously rendered each group as a full
grid, which made scrolling past many groups tedious. When a feed has two
or more groups, render each group's items in a compact horizontal
carousel, matching what Thorium does.
Each carousel is a horizontally virtualized react-virtuoso list, so only
the covers in view are mounted and fetched; off-screen covers load lazily
as the row is scrolled. Scroll arrows page through by index and stay
centered on the cover artwork.
Book items also get rounded covers (matching the library bookshelf) and
drop the inline acquisition badge, which remains on the publication
detail page.
