A target's min, max, median and average latency now come from one list
of its answers, through latencyStats(), which the summary's figures use
too, so the median is written once. latencyHex() and latencyClass() read
one table of color limits in CONFIG. The health thresholds, the debug
log's length, the gateway check's timeout, the recovery probe's number
of hosts and interval, how often the rows are sorted and the delay
before the first sparkline resize are CONFIG entries, read where the
numbers were. HostState's minLatency(), maxLatency(), averageLatency()
and medianLatency() are gone; the statistics test reads historyStats().
Nothing the page does or shows changes. A unit test now covers the
summary's figures.

A host row escapes the name and URL it writes into its markup with a new
escapeHTML function, and the debug log builds each line as an element
whose text is set, so neither is read as HTML once targets can be
configured. A unit test builds the row of a target whose name and URL
hold < > " & and ' and checks each comes out escaped; hostRowHTML is
exported for it.
README.md stops calling CONFIG frozen: the interval menu sets
updateInterval, and the timeouts, history span and axis ticks are
computed from it. AppState declares _recoveryProbeId and
_recoveryProbeChecks, the sparkline axis functions drop the parameters
they never used, and HostState's history comment names both entry
shapes.

New table-driven tests in test/unit/main.test.js: humanDuration, the
figure and sparkline colours either side of each latency boundary, a
target's min, max, average and median over an empty history, an
all-unreachable one, a mixed one, one of only answers and one whose
answers have different numbers of digits, and the four health states
either side of their thresholds, with targets found unreachable counted
as timed out. src/main.js exports the four names they need.
package.json gains a test script, which script/frontend-test runs with
the dot reporter and, if a test fails, again with the spec reporter
before failing. NODE_OPTIONS picks the reporter, since yarn appends its
arguments after the test files.

script/lint ran prettier --check, the same check script/fmt-check
runs, so the JavaScript had no linter. eslint now runs with its
recommended rules, set in eslint.config.js, in a new frontend-lint
stage of Dockerfile built from the pinned node image and the lockfile.
The frontend stage copies a file from it, as the builder stage does
from the Go lint stage, so the image cannot build unless eslint passed.
script/lint builds both lint stages with --no-cache and runs no linter
on the host; script/fmt-check keeps prettier on the host, and
script/frontend-check drops its lint step. The viewport harness fixes
the two kinds of finding eslint made. bootstrap wants node 22.13.0, as
eslint 10 does. Also covers item 2 of
#28.

The viewport harness's tap-target check required at least 10 visible
pin buttons while 26 render, so pin buttons missing from up to 16 rows
went unnoticed. It now expects one per WAN host row. The host row count
the harness gathers, which the app-rendered check also reads, counts
only the WAN host rows, since the local host rows have no pin button.
Each control's minimum is now worked out from the gathered facts.
TODO.md's harness entry no longer says every check guards itself: the
overflow, viewport-edge and clipped-text checks rely on app-rendered.

tick drew no row until the round's slowest check ended, up to 24
seconds at a 30-second interval since checks time out at 80% of it.
Each check now pushes its sample and redraws its row as it ends. When
the last check ends, every row is redrawn, so none still reads "paused"
after a pause and resume, and sorting, the summary, the health box and
offline detection run once. A check that ends while paused or after its
round is given up draws nothing, and the first round is still discarded
as a whole. The row is looked up when the check ends, as a pin click can
re-sort the rows mid-round.
Unit tests run tick on the mocked clock against a stand-in page.
Model: opus-5-5
Each target check now times out after 80% of the refresh interval, 24
seconds at 30 seconds, where it was capped at 3 seconds, so slow, far
targets are recorded with their real time. Rounds never overlap: a
round gives up the last round's checks if they are still waiting, which
happens only when a round starts early, after an interval change or
when the recovery probe finds a target answering. The probe still
checks every half second, giving up its previous checks, so they do not
pile up.
The frontend has its first unit tests, run by script/frontend-test with
Node's built-in test runner on a mocked clock. index.html now links
src/styles.css, which src/main.js imported, since Node cannot import
CSS.

`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.
