Thermograph monorepo: graded-climate API + SSR frontend + infra, domain-specific containerized deploys

app.js carried the whole SVG chart implementation (~380 lines: palette,
percentile fans, the shared line-series renderer, per-metric wrappers,
pointer hover) alongside its page logic. That moves to chart.js: the
drawing dimensions live there as live-bound module state behind
setChartWidth(); attachChartHover takes the day list as a parameter
instead of reaching into page globals. app.js keeps buildChart and the
PNG export — page orchestration — and drops to ~500 lines. Any page can
now plot a metric series (e.g. a history sparkline on the day page).
calendar.js's hand-rolled streaming loader — bounded-parallel pool,
token cancellation, stale-while-revalidate re-merge — becomes
cache.js chunkedFetch(urls, {ttl, concurrency, isCurrent, onResult});
fetchCalendar keeps only its intent (chunk URLs, day merge, contiguous-
prefix rendering). Same pool semantics, verbatim.
Verified: node --check; 108 backend tests; headless-Chromium smoke on
all five pages against live data (chart renders + metric toggle,
calendar grid streams + metric switch, ladders, compare, legend).
