events.ts's handlers for a download in progress, finished and failed,
and for Signals' new hits, ran in no test. The fixture server has a
show to download from by hand: one episode sent over two seconds and
one that always fails, added with a word nothing has so that nothing
downloads on its own. Downloading the slow one fills its bar, the count
line says how far, the toast names the file and the row shows it
downloaded; another person with a page open, not subscribed, hears of
none of it (#294). The broken one says which item failed and what to
do (#304), and its bar stops. A Signal open on its page shows its new
hits and its count as soon as a pass picks them out, without a reload;
its folder is opened from the keyboard.
