A Reporter beside AppState POSTs each host's unreported, non-paused
samples to /api/v1/reports every reportInterval (default 60s).
buildReport is an exported pure function of host state; init() runs only
when #app exists, so a test can import the module. A per-host mark
advances only on a delivered POST. At most one report POST is pending at
a time and it is abandoned after half the interval, so a slow POST never
overlaps the next report and a mark never moves backwards. The samples of
an abandoned POST are sent again at the next interval, so a backend that
stored them but answered late receives them twice. Failure is quiet and
never blocks probing. vite.config.js proxies /api for yarn dev.

`make frontend-viewport-test` builds `dist/`, serves it from the same
digest-pinned nginx image and nginx.conf the shipping container uses, and
drives a digest-pinned headless Chrome over CDP. Viewport widths are derived
from the app's own @media breakpoints rather than a list of phone models: each
breakpoint is tested one pixel below, on, and above, plus four anchor
viewports. Assertions are on computed layout — horizontal overflow, off-screen
elements, clipped text, 44x44 tap targets, host-row reflow — not screenshots,
and each check declares the minimum elements it must find so a stale selector
fails instead of passing blind against a page it is not measuring. Kept out of
`make check`: it needs Docker and takes minutes. Proven able to fail before
being trusted.

Local CPE (192.168.100.1) is always monitored. On startup, probe
192.168.1.1, 192.168.0.1, 192.168.8.1, and 10.0.0.1 in parallel
and add whichever responds first as "Local Gateway".
