The page hotlinked ~100 AniList CDN covers per load and some failed at random.
The reader now downloads each catalog cover once (sequential, ~1/s, stops on
401/403/429, images up to 2 MB) into data/greatest-covers/ and serves it from
/api/greatest-cover with a year-long browser cache; until a copy exists the
route redirects to the catalog URL. The page also accepts the server's
relative cover URLs, so owned titles show their library cover again.
GREATEST_COVER_WARM=0 turns the downloads off (tests, offline installs).

New POST /api/admin/user/role {name, admin}: admin-only (checked on the
server), keeps the password and sessions, takes effect on the target's
current session at once, logs who changed whom. Revoking your own
rights is refused, so at least one admin always remains. Settings ->
Users & access shows "Make admin" / "Remove admin" next to every other
user, with a confirmation. Test: normal users and anonymous callers are
refused, input checks, promotion and revocation apply immediately and
are saved.
