Enter on the live feed names *this* packet, so the dialog rightly opens holding
one — but there was then no way back to the stream from inside it. The reader
who walked up to the newest packet hit a clamp, and following the feed again
meant Esc, ↑ on the list, and re-opening whatever had landed since.
The pin is now the viewer's stop too, on the same key it is on the feed: ↑ off
the newest packet, and Home from anywhere, holds the top *position* rather than
a packet, so every arrival becomes the card being read. The title says
`following` where it would say `n/total` — what changes under the pin is the
card, not the number — and ↓ steps back off onto whichever packet is showing at
that moment, keeping the scroll the reader had in it, because that card is the
one they were already reading.
Both ends move together: the viewer tells the feed when it pins (`on_pin`), the
way it already tells it when it lands on a packet, so a dialog closed while
following leaves the list following, and one closed on a packet still lands on
that packet. Only a live list has the stop at all — over a snapshot there is
nothing to follow, so ↑ on the newest packet clamps as it always did.
The footer follows the moves rather than the count: `↓ hold packet` on the pin,
`↑ follow · ↓ older` one stop below it (two keys doing different things, so an
atom each), and the plain pair everywhere else. On the console the `Newest`
chip reaches the pin, exactly as the feed's `Top` chip does, which is also why
the jump chips light over a live list holding a single packet.
