The #day-body card grid used bare 1fr columns, whose minimum track size is
the widest card's min-content. The humidity ladder's nowrap value ranges
("17.3 g/m³–19.9 g/m³") pushed that minimum past the viewport on phones —
the page scrolled sideways 21px at 390px wide and 51px at 360px — so the
whole Day view sat off-center.
- Size #day-body columns with minmax(0, 1fr) so card content can never
widen the page canvas.
- Collapse the unit repeated on both range bounds ("17.3–19.9 g/m³") and
drop it from the observed ◀ marker; the unit still reads from the card
summary, median, and historical range.
- Let .ladder-val wrap as a last resort instead of nowrap-widening the row.
- Rebalance the mobile ladder tracks (pct 54→46, marker 48→42) so the
longest range stays on one line down to ~375px screens; narrower than
that it wraps cleanly at the unit.
The frontend was classic scripts sharing one global scope, with a
load-order contract enforced only by comments (leaflet -> nav ->
shared -> mappicker -> page) and hand-rolled window.Thermograph /
window.LocationPicker namespaces. Page scripts now import what they use;
the dependency graph replaces the ordering contract, and no app globals
remain (Leaflet stays a classic script / global L, loaded first).
nav.js had grown four concerns; it's now three single-purpose modules:
- nav.js: last-location memory + header view-links + locHash.
- units.js: the °F/°C toggle and unit-aware formatting. The compare
special case is gone — pages that want the toggle import units.js;
compare simply doesn't.
- cache.js: the IndexedDB response cache, SWR getJSON, bundle-seeded
view prefetch and neighbor warming. prefetchViews(lat, lon, ownViews)
now takes the calling page's own view names instead of a page-identity
map (VIEW_OWN) — adding a page no longer means editing this module.
The slice->URL map stays here as bundle-contract knowledge.
frontend/package.json ({"type": "module"}) makes CI's node --check
parse the files as modules.
Verified: node --check on all files as modules; 108 backend tests;
headless-Chromium smoke across all five pages against live data — zero
console/page errors, all render assertions pass (cards, chart, calendar
grid + metric switch, ladders, compare ranking, legend scales).
The page scripts each re-declared the shared presentation layer — the tier
color table existed in four places (app.js, calendar.js, day.js, style.css)
and the scale label tables in three (plus legend.html's own drifting copy),
alongside per-page copies of the dryness ramp, formatters, ord, todayISO,
esc, the weather icons/summary, month helpers and the 2-year range chunker.
~240 duplicated lines deleted (net -236 with the new module included).
- frontend/shared.js (IIFE, extends window.Thermograph): tier colors read
from style.css's :root custom properties at load — the CSS is now the
single source of truth; the JS map exists only because inline-SVG work
(chart + PNG export) needs literal values, with hex fallbacks for a
missing stylesheet. Plus SCALE_TEMP/SCALE_RAIN, drynessColor, fmt*, ord,
todayISO, esc, placeLabel, month/chunk date helpers, clickOpensPicker,
and the weatherType summary (dsr-aware; the day page just omits dsr).
- nav.js: wrapped in an IIFE — its ~15 top-level functions were globals in
the shared classic-script scope, and a leaked locHash collided with page
destructuring (caught by the browser smoke, not by node --check).
locHash is now exported and used by all 8 former hand-built hash sites.
- mappicker.js: initFindButton/setFindLabel replace the Find-button block
each page rebuilt.
- legend.html renders its scales from the shared tables, so the guide can
no longer drift from what the app shows.
Verified: node --check on all JS; 108 backend tests; headless-Chromium
smoke over all five pages against live data — no console/page errors,
legend rows 9/9, weekly 7 cards + colored chart/key/table + metric toggle,
calendar grid + key + metric switch, day 7 ladders + weather icon,
compare seeded rank card.
* Picker map: smaller city labels, darker/bolder roads (split tile layers)
Split the CARTO Voyager basemap into two raster layers so label size and road
weight are independent: a labels-free base upscaled via tileSize 512 + zoomOffset
-1 (bold, prominent roads) plus a labels-only layer at natural size on top (small,
crisp city names). The darken/saturate filter now targets the base layer only
(.mp-base: brightness .92, contrast 1.12), deepening the roads while leaving label
text at full contrast.

* Location label: show coordinates immediately, then resolve to place name
On selecting a location, write the raw coordinates to the location label right
away, so the user sees the picked spot instantly instead of a stale/blank label.
The existing post-fetch render already overwrites it with the reverse-geocoded
"neighborhood, city, region" string (data.place), so the label now reads
coords → place name live.
- app.js / calendar.js / day.js: set coords in the selection handler before the
fetch; the render/initOnce overwrite is unchanged.
- compare.js: show coordinates through the pending + loading states (instead of
"Locating…") so each chip's coords are replaced live by the place name once
scored.

* Revert "Merge pull request #22 from griffemi/fem-orchid-palette"
This reverts commit f7d16238f2, reversing
changes made to 34e4fed1f0.
* Restyle location-picker map: themed CARTO basemap + branded pin
Replace the plain gray OpenStreetMap raster in the location picker with a
theme-aware CARTO basemap (no API key): sleek "dark matter" tiles under the
dark theme, colorful "voyager" tiles under the light theme, so the map
matches whichever is active. Swap Leaflet's default blue marker for an
accent-colored teardrop pin (the same glyph the Find button uses), and theme
the zoom controls + attribution to sit in the app's surfaces.
- mappicker.js: theme-aware CARTO tileLayer (retina, CARTO attribution);
L.divIcon "mp-pin" used for the marker
- style.css: .mp-pin styling, themed .leaflet-bar / attribution, map shadow

A shared units module in nav.js holds the active unit (persisted), converts
Fahrenheit API values for display, and notifies pages to repaint on a switch.
A segmented °F/°C control is injected into the top-right of every header
(left of the view tabs); Weekly, Day and Calendar convert every temperature —
cards, dense timeline, trend chart axis/labels, tooltips and the PNG export —
while wind, humidity and precip stay as-is. Compare keeps its Fahrenheit
comfort slider, so the toggle is hidden there.
Replace the clinical blue→green→red diverging temperature scale, the
green→navy rain ramp, and the orange accent with a warmer, more vibrant
"Orchid Sunset" palette: violet/lavender cool end, soft blush middle,
rose/magenta warm end, hot-pink accent.
Keeps the diverging structure grading relies on (cool reads cold, warm
reads hot) and updates every mirror of the literals so PNG export and the
self-contained subpages stay in sync:
- style.css :root tier + precip vars, accent, cta-cal gradient/shadows,
dry-metric toggle; light-theme overrides for the near-white middle tiers
so "Normal" stays legible on white
- app.js TIER_COLORS, chartPalette() fallbacks, dry-streak ramp
- calendar.js TIER_COLORS, PRECIP_COLORS, dry-streak ramp
- day.js TIER_COLORS, PRECIP_COLORS, DRY_COLOR

* Compress API responses and revalidate static assets instead of re-downloading
- Add GZipMiddleware (min 1 KB): the 2-year calendar JSON shrinks ~6-8x.
- Serve pages/assets with Cache-Control: no-cache instead of no-store, so
browsers revalidate via the ETag/Last-Modified that FileResponse and
StaticFiles already emit. Unchanged assets now cost an empty 304 rather
than a full transfer on every page navigation, while deploys still show
up immediately.
* Persist derived responses in SQLite so grading is computed once per cell, not per request
New data/thermograph.sqlite (WAL) holds what's derived from the raw parquet
records — finished grade/calendar/day/forecast payloads and reverse-geocode
labels — so the expensive work (notably the 2-year calendar grade_range, ~270ms)
becomes a ~5ms database read that survives restarts and is shared across views.
Raw parquet stays the source of truth; the store is a pure accelerator (every
reader falls back to recomputing on a miss, and deleting the db is a safe reset).
Freshness is token-driven, not clock-driven: each cached payload is validated by
a token encoding what it was computed from (payload schema version, the archive
record's end date, the recent-fetch stamp). The existing freshness drivers are
untouched — get_history still tops up the tail hourly and get_recent_forecast
still refetches hourly — and tokens are derived from what they return, so cached
payloads expire exactly when their inputs change. The same tokens double as weak
ETags: If-None-Match answers with an empty 304 without touching the payload.
- backend/store.py: derived-payload + revgeo tables, thread-local WAL conns,
every helper fail-soft.
- app.py: endpoints split into pure payload builders + HTTP/caching shells; the
in-memory 10-minute _CAL_CACHE is retired (superseded by the persistent store).
- climate.py: revgeo persisted through the store; recent_stamp() and
load_cached_history() (no-network read) helpers.
- backend/migrate.py + make migrate: idempotent, resumable backfill of the store
from existing parquet caches (default calendar span + latest-day detail +
revgeo, ≤1 throttled Nominatim call per unlabeled cell). Never fetches weather.
- grid.from_id(): rebuild a cell from its cache filename (migrate tooling).
* Add /api/v2/cell: one bundle carrying every view's payload
GET /api/v2/cell?lat&lon returns the grade, forecast, calendar (last 24 months)
and day (today) payloads in one response, each the exact payload its per-view
endpoint returns — built by the same builders and cached under the same
derived-store keys/tokens — paired with the etag that endpoint would emit. The
frontend can warm all views with a single request, seed its per-view cache from
the slices, and later revalidate each view individually with If-None-Match. The
bundle's own etag combines the slices', so an unchanged bundle is an empty 304.
prefetch=1 is a warm-only mode for neighbor-cell prefetching with a hard
guarantee: it never spends weather-API quota. A cell with no cached archive
answers 204, and only the history-derived slices (calendar + latest-day detail)
are built. At most one Nominatim lookup for a never-labeled cell.
* Frontend: IndexedDB response cache with stale-while-revalidate + bundle prefetch
The per-URL response cache moves from localStorage/sessionStorage (~5 MB quota,
which multi-year calendar payloads regularly blew through) to IndexedDB, with an
in-memory map in front. Entries carry the server's ETag, so anything stale
revalidates conditionally — unchanged data costs an empty 304 and a re-stamp,
never a re-transfer. On network failure the stale copy is served over an error.
getJSON gains an optional onUpdate callback opting into stale-while-revalidate:
the three views (weekly, day, calendar) now render a cached copy immediately —
spinners are delayed 150ms so warm loads never flash-blank — and repaint only if
background revalidation finds changed data. New data shows up the moment it
exists instead of waiting out a TTL.
Cross-view prefetch collapses from one request per view to a single /api/v2/cell
bundle, whose slices (exact per-view payloads + their etags) are seeded under the
URLs each view actually requests; the bundle call itself is conditional via a
remembered etag. Afterwards the 8 surrounding grid cells are warmed server-side
with prefetch=1 (never spends weather-API quota; staggered ≥1.1s for the one
possible Nominatim lookup each), so tapping nearby lands on already-graded data.
Legacy tg:* storage entries are cleared once; cache entries untouched for two
weeks are pruned on page load.
The Weekly location card joined coordinates, cell size, climatology range
and sample count into one dot-separated meta line. Stack them as one fact
per line so the important context reads top-down instead of as a run of
tags. Drop the '~N sq mi cell' wording from the Weekly/Day/Calendar meta
lines and the map hint.
Reverse-geocode at zoom 14 and prefer neighbourhood/suburb ahead of the
city so labels read 'Gowanus, New York' when OSM has that detail, falling
back to the city (and county) when it doesn't.
Replace the recurring '±7-day window' phrasing in the UI with plain
language ('a typical day', 'days around this date', 'typical climate').
