The feed keeps up, and stops moving the page while you read.

A phone freezes a backgrounded tab: timers stop and the relay sockets are
cut, so the feed came back holding whatever it had when you left and only
caught up if you pulled it down by hand. Features now hear about the
return — app.js calls f.resumed(awayMs) on focus — and the feed answers
it by forcing a pass past the thirty-second throttle and rebuilding its
subscriptions, which were talking to sockets that no longer exist. A
blink between apps (under five seconds) is left alone.

That catch-up raises the second problem rather than solving it: dropping
eight posts in at the top moves the words under the thumb of whoever was
reading. So posts that arrive on their own — live, or as a catch-up —
wait when you're scrolled away from the top. A floating pill says how
many, and the tap that lets them in also takes you up to them. Scrolling
back to the top by yourself lets them in too, since up there they cost
nothing. Anything you actually asked for still goes straight in.

Also, on profiles that still show an npub: the batch now falls back to
the relays whose whole job is indexing kind 0 (purplepag.es and friends),
which we never read notes from and so never asked. profile-batch-test's
"handful of asks" bound was a fraction of the row count, which that
fallback broke; the property it means to assert is that the number does
NOT grow with the rows, so it is a constant now.

tools/feed-live-test.js drives a real signed event down a real open
subscription — an unsigned fake is dropped by the signature gate and
would prove nothing — and checks the page does not move, the pill says
"1 new post", tapping it scrolls to the top, and coming back from hidden
re-asks the relays on its own.
