Each page's script turns a one-character braille spinner next to the
status whenever a stats answer counts more messages than the one
before. Its colour cycles as rtnetmon's does. A separate check runs
every second. Once no such answer has come for three refresh periods,
15 seconds on / and 6 on /status, it shows "stale" and the seconds
since, in the page's disconnected colour. A failed or hung request
counts as no fresh answer. On / the card has no room beside
"Connected", so the indicator sits on the line under it. A test renders
both pages and checks the indicator follows the status element.
