The mark is a quantized climb through the temperature-band tokens
(cold -> cool -> normal -> warm -> hot -> very-hot) to a rec-hot
terminal at a dashed record line, on the dark rounded tile.
- favicon.svg (canonical) + favicon-16/32/48.png fallbacks; the 16px
raster drops the whisper strata and record dash so the climb survives
- apple-touch-icon.png 180 rendered edge-to-edge (iOS supplies rounding)
- maskable 192/512 scale the artwork 0.78 about center so every element
clears the 40%-radius circular safe zone; any-purpose 192/512 and the
512 OG logo.png regenerated; reused filenames cache-busted with ?v=2
- header lockup: inline glyph referencing var(--cold) etc so a palette
change propagates, beside a lowercase 650-weight wordmark
- PNGs are palette-quantized with the band/chrome hexes pinned exact;
full asset set is ~20 KB

Put Alerts in the main navigation (after Climate) across the interactive pages
and the SEO/climate pages, so it's a discoverable entry point rather than only the
header bell. The bell stays; this is an additional way in.
The signed-out /alerts gate now leads with a clear "What are weather alerts?"
explainer — what they do, how the percentile threshold works, and an example —
above the sign-in / create-account button, so visitors understand the feature
before signing in.
The extra nav item pushed the inline header past ~800px into a horizontal
scrollbar; trim the tab padding in the 641–1000px band so the row fits again
(phones already collapse into the hamburger).
Faster search-engine indexing for the ~14k climate/city/record URLs:
- IndexNow (backend/indexnow.py): instantly notify Bing/DuckDuckGo/Yandex of new
or changed URLs. Per-host key resolved env → gitignored file → generated (mirrors
push.py), served at /{key}.txt, and echoed in submissions. `submit_all()` + a
`make indexnow` CLI push every indexable URL, batched under the 10k cap. Google
doesn't use IndexNow, so it stays on the sitemap.
- Sitemap: replace the per-request today() <lastmod> (which churns every fetch and
trains crawlers to ignore lastmod) with a stable content-build date; factor the
URL list into public_paths() shared with IndexNow so the two never drift.
- Search-console verification: render google-site-verification + msvalidate.01
<meta> tags from env into every page's <head> — the SEO pages via base.html.j2
and the static pages (incl. the homepage Google verifies) via _page().
- Docs: env example documents the three new vars; .gitignore ignores the key.
Tests: key-file route, stable single-date lastmod, IndexNow payload/batching, and
verification meta on both SEO and static pages.
The server-rendered SEO pages shared base.html.j2's nav but carried no JS, so
they lacked the °F/°C toggle and account/bell, and their temperatures were baked
as dual-unit strings that couldn't respond to a toggle.
- Load units.js + account.js + climate.js on base.html.j2, so every SEO page gets
the same header as the interactive pages (nav + °F/°C toggle + account + bell).
- Emit each temperature as <span class="temp" data-temp-f> (default °F text, real
for crawlers/no-JS); climate.js rewrites them to the active unit on load and on
toggle. Tint classes stay pinned to absolute °F. Drops the inline "(NN°C)".
- Make account.js base-aware: derive the app base from import.meta.url so its
api/v2 fetches and the alerts links resolve from deep /climate/{slug} URLs
instead of 404ing. Equivalent on the depth-1 interactive pages.
- Default the unit from the browser locale for first-time visitors (no stored
pref): en-US → °F, everyone else → °C. A stored choice always wins.
- Compact the mobile menu: narrower panel (208px), tighter rows, and the nav
list now stretches to the panel width and left-aligns (it was centering because
the base .view-nav align-self:center overrode the panel's stretch).
- Stylish separation between entries: an inset hairline between each nav item,
suppressed around the active pill so nothing crosses it.
- Rename the "Day" view to "Day Detail" across the app nav, and add it to the
climate/city page nav (base.html.j2), which was missing it.
On phones the header spanned two rows: the title block plus a control bar of
the °F/°C toggle, bell, account and hamburger. Wrap the nav in a .nav-panel
inside the <details> menu and inject the °F/°C toggle and account/bell into that
panel instead of into the header row. On desktop the panel is display:contents,
so the inline top bar renders exactly as before (order restored via flex order);
on phones the panel becomes a right-anchored, viewport-clamped dropdown and the
header collapses to a single row (logo + name + hamburger, tagline hidden).
The viewport clamp also fixes the SEO/city pages, whose menu dropdown previously
ran off-screen.
- Collapse the view navigation into a hamburger menu on phones. The nav is
wrapped in a <details> (pure CSS, no JS — so it works on the crawlable SEO
pages too): transparent (display:contents) on desktop so the tabs render
inline, a dropdown behind a hamburger under 640px. The °F/°C toggle, bell and
account stay in the header bar; units.js/account.js now anchor their injected
controls on the wrapper.
- Replace the header logo: the ▚ glyph was a rotated Unicode char that fonts
rendered inconsistently (warped). Use a crisp inline SVG of the two accent
squares (currentColor) across all headers.
- Month pages: turn the plain "Visiting <city> in <month>?" line into a bordered
callout with a CTA button, matching the city page's travel box.
Verified in Firefox and Chromium at desktop and 390px, light and dark: desktop
nav inline, mobile hamburger opens the dropdown, logo crisp, travel note styled.
* SEO: generate curated city set for crawlable climate pages
gen_cities.py reuses the GeoNames index places.py already parses to select the top
~500 metros by population, assigns each a stable URL-safe slug (dropping admin1 when
it repeats the city name), and writes committed backend/cities.json. cities.py loads
it lazily with slug lookup, all_slugs(), display_name(), and by_country() grouping
for the upcoming hub + sitemap.
* SEO: rendering core, robots.txt, sitemap.xml, and metadata hygiene
- content.py: Jinja2 environment + HTML responder (ETag/304), dynamic /robots.txt
(disallows /api and /alerts, points at the sitemap) and /sitemap.xml (enumerates
the home/static pages plus every city, month, and records URL from cities.py).
Registered on the app before the StaticFiles mount so the routes win.
- templates/base.html.j2: shared layout with unique title/description, self-
referential canonical, Open Graph, favicon/manifest, header nav (adds a Climate
link) and a footer link graph.
- Give each existing page a unique <meta description> (were 5x identical) and a
self-referential <link rel=canonical>; add WebApplication JSON-LD to the home page.
- Pin jinja2.
* SEO: server-rendered per-city climate page (/climate/{slug})
The keystone crawlable page: for a city it snaps to the grid cell, loads the
archive (fetching once if missing, self-healing), and renders as real HTML — a
'how today compares' block (grade + percentile per metric from grade_day, tinted
by tier), a monthly normals table (climatology at each month's 15th, shown in °F
and °C), all-time records (new grading.all_time_records helper), a breadcrumb,
Dataset+Place+BreadcrumbList JSON-LD, self-referential canonical, and links into
the interactive tool + month/records pages. Content-page CSS added to style.css
(renamed the table class to avoid colliding with the app's .normals flex row).
* SEO: month (/climate/{slug}/{month}) and records (/climate/{slug}/records) pages
Month pages render the exact-month long-tail ('average weather in {city} in
{month}') with that month's average high/low, typical p10-p90 range, month-specific
records, and prev/next month links. Records pages show all-time record highs/lows
per metric with dates (grading.all_time_records). Shared _resolve_city helper; the
literal /records route is registered before the {month} param and month names are
validated (unknown month -> 404).
* SEO: climate hub, weather glossary, and about/methodology pages
- /climate: crawlable directory of all ~500 cities grouped by country — the
internal-link graph that lets search engines discover every city page.
- /glossary + /glossary/{term}: plain-language definitions (climate normal,
percentile, temperature anomaly, feels-like, heat index, wind chill, humidity,
reanalysis) with DefinedTerm JSON-LD and cross-links into the tool.
- /about: methodology page (ERA5 data source, 45-year baseline, +/-7-day window,
percentile grading) for E-E-A-T. All linked from the shared footer.
* SEO: archive warmer, content-page tests, and deploy docs
- warm_cities.py: paced, idempotent offline warmer that pre-fetches each city
cell's archive so /climate pages serve from cache and a crawl can't burst the
archive quota (pages self-heal if hit before warming).
- tests/test_content.py: city-set slug uniqueness/lookup, robots.txt, sitemap
enumerating city/month/records URLs, and that a rendered city page carries the
stats + canonical + Dataset JSON-LD in the HTML; plus month/records/hub/glossary/
about routing and 404s.
- DEPLOY.md: document the content pages, the warm step, and submitting the sitemap.
