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').
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.
