sxyprn's "latest" listing sends items whose thumb is the bare string
"https:". Resolved against the page -- which is what new URL(url, location)
does with anything that isn't absolute -- that becomes our own address, so
the card raced our own HTML as if it were a picture, pinned our origin to
the proxy for the rest of the session, and asked /api/image to fetch
"https:" (a 400, every time). An address that doesn't stand on its own is
no thumbnail at all, and is now treated as one: no src, no race, no
request, and the card keeps its placeholder.
While in here: a thumbnail that failed had exactly one more chance, the
proxy, and images already on the proxy route had none at all -- so one
refused connection left a card empty for as long as it stayed mounted. A
failure now walks a short ladder instead: the other route, then both again
after a pause. Bounded and backed off, and dropped the moment the card is
rebound, so a page of genuinely dead images costs a handful of requests
rather than a storm.
