The bar showed each segment's share but not what it meant, leaning on the
coloured below/above-comfort text to explain it. Replace that text with a
per-card key directly under the bar: a colour swatch + plain name + share for
every bucket present (Too cold / Cool / Comfortable / Warm / Too hot), in the
same cold→hot order as the bar. Every span is spelled out, so a 1% sliver is
as clear as a 60% block, and small segments no longer need to fit a label
inside them. Bar segments also carry a hover title. The redundant top legend
is removed (each card now names its own colours), and the leftover summary
line keeps just the tolerance share and typical miss.
The diverging comfort bar read as noise — half the track sat empty and the
lighter/saturated tolerance split was unlabeled, so the coloured chunks had
no clear meaning. Replace it with one full-width bar that is 100% of the
place's days, split into five temperature buckets ordered cold → hot in the
site's own temperature colours: too cold, cool (within tolerance),
comfortable, warm (within tolerance), too hot. Wide segments print their
share inline, and a legend above the cards names every colour. More blue =
runs cold, more red = runs hot, with no empty space to decode.
Ranking by raw comfort% tied extreme places (Death Valley ranked #2 just
because 26% of days happened to land in-band). Replace it with a weighted
score that folds in tolerance days and miss magnitude, add an outer
tolerance range, and fix the Feels basis.
- Match score (0–100): each day scores full credit inside comfort [lo,hi],
partial credit inside the tolerance range (ramped 1→0 by how far past the
comfort edge it lands), zero beyond tolerance. Rank by the mean; tie-break
by smaller typical miss. Death Valley's hot days now score ~0 so it drops
to last. The score is the card's headline number.
- Tolerance range [tlo, thi] as an outer dual-thumb pair on the same track
(four handles, tlo ≤ lo ≤ hi ≤ thi), persisted + in the share hash.
Defaults to comfort widened 10° each side. The diverging bar now splits
each side into a within-tolerance band (lighter, near centre) and a
beyond-tolerance band (saturated), and the baseline strip shades the
tolerance range faintly around the comfort band.
- Feels basis now judges the felt daytime high (fmax) instead of the
combined `feels` metric, which reports whichever apparent extreme is
furthest from 65°F — in mild climates that flips to the cold overnight
low in winter and made comfortable days nearly vanish.
Rework the compare results so the winner, the cold/warm skew, and the
places' baselines all read at a glance, and make loading obvious.
- Diverging comfort bar per place: colder days grow left of a fixed
centre comfort marker, warmer days grow right, both on one 0–100%
scale — a cold-skewed place and a hot-skewed one mirror each other and
compare directly. Replaces the left-anchored stacked bar + 3-up stat
grid (the grid was the main mobile-clutter source).
- Baseline strip above the cards: every place's average basis temp on
one shared °F axis with the comfort range shaded, plus a middle-80%
(p10–p90) spread, so baselines line up side by side. computeStats now
also returns avgTemp/p10/p90.
- Stronger winner: filled accent rank badge, accent card frame, and a
"Best match" flag on the subline.
- Real in-progress state: a CSS spinner ring on loading chips, a queued
dot on pending chips, an inline spinner in the header, and shimmering
skeleton cards for still-loading places (previously only muted text —
the referenced chip spinner never existed).
- Mobile: tighter baseline gutter/axis and caption sizing.
* Compare: comfort range slicer + per-location climate distribution
Replace the comfort-point + band sliders with a single dual-handle range
slicer: a day hits comfort when its judged temperature lands in [lo, hi];
below lo is colder, above hi is warmer. State is the range in °F, so old
c/t links and stored prefs migrate to a range. Ranking, average miss, and
the typical-miss figure are all computed against the range.
Add a climate-distribution section below the ranked cards, independent of
the comfort filter: its own metric selector (High/Low/Feels/Humid/Wind/
Gust/Precip/Dry streak) plus a share/count toggle render one Record-Low→
Record-High distribution strip per location, mirroring the calendar.
Extract the calendar's category bucketing and distribution strip into
shared metricBuckets/distStrip so both pages share one implementation;
calendar output is unchanged.
* Carry the calendar's wet/dry scale-group logic into the shared distribution helpers
* Carry the precip strip's per-tier label hook into the shared distribution helper
compare.js never imported units.js, so the header unit toggle was never
built on the compare page and every temperature was stuck in °F. Import
units.js (which builds the toggle) and route the comfort target, comfort
band, and the colder/warmer/typical-miss figures through the unit
formatters, re-rendering on unit change. State stays in °F (the API's
unit); only the displayed numbers convert.
Add fmtDelta for degree *differences* (band, average miss), which scale
by 5/9 without the 32° offset that absolute temperatures use.
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.
- Widen the content column in steps at 1680/2400/3400px so 1440p-4K monitors
get real layout instead of a 1200px strip; header brand aligns with it.
- Calendar: months flow as a responsive multi-column grid (year-at-a-glance
on desktop, single column on phones); the time-filter panel spans the
content width as one row (Range | Seasons/Years/Weather) on desktop;
category-totals strip widened to 720px.
- Day: metric ladder cards lay out 2-up from 1000px (3-up at 4K).
- Weekly: the calendar CTA is a compact button (sub-line removed); the trend
chart's drawing width now tracks its container (~1.5 CSS px per SVG unit,
redrawn on resize) so wide screens gain plot room instead of magnification.
- Compare: scope the rank-bar segment colors to .cmp-seg — the bare
.cmp-comfort rule was painting a green box behind the comfort slider.
- Calendar/Compare From-To month inputs open the native month picker on
click (input.showPicker, ignored where unsupported).
- CLAUDE.md: require validating design changes at mobile/tablet/1080p/2K/4K.
Add a lightweight GET /api/v2/place?lat=&lon= endpoint that snaps to the grid
cell and returns the reverse-geocoded "neighborhood, city, region" label (the
same string the view endpoints expose as place, cached + throttled). On the
compare page, adding a location now fires this right away so the chip flips from
coordinates to the place name immediately — instead of only resolving when the
full comparison loads on Refresh. Best-effort: the series load still resolves the
name, so a failed/again call is harmless.

* 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.

The whole comparison — locations, comfort target, band, judged temperature
and date range — is now encoded in the URL hash (c/t/b/s/e/loc) and read
back on load, so a link reproduces exactly what's on screen. Comfort, band
and judged-temperature edits still re-rank instantly and update the hash
without a fetch.
Editing the date range or the location set no longer refetches on its own:
it marks the comparison dirty and reveals a single "Refresh comparison"
button next to Add location; the load runs only when it's tapped. Pending
locations show a dashed chip until then. The initial view (from a shared
link, the saved set, or the last-viewed spot) still loads on arrival.
Compare page (frontend/compare.{html,js} + /thermograph/compare route):
line up several places over a date range and rank which best matches a
comfort temperature. Per location it pulls the same daily record the
Calendar uses and, per day, takes a chosen temperature (daytime high /
daily mean / overnight low / feels-like) against the comfort target. A
day "hits comfort" when it lands within an adjustable band; otherwise it
counts as colder or warmer and the average miss is tracked. Results are
ranked by comfort-day share (tie-broken by the smaller typical miss),
with a diverging below/comfort/above bar and per-bucket stats. Comfort,
band and judged temperature re-rank instantly client-side; only the
location set or date range trigger a data load (shared calendar cache).
Feels calendar filter: drop the comfort-temperature slider and the
client-side felt-high/felt-low re-pick. The Feels metric now colors by
the server's combined feels-like value like the other metrics, so its
tab matches the rest of the metric selector.
