Make the app installable and deliver existing alert notifications as OS push, alongside the in-app bell. Backend: - PushSubscription model (per-device endpoint + keys, owned by a user) and register/unregister/test endpoints under /api/v2/push, cookie-auth scoped to the user like the subscription routes. - push.py: VAPID key management (env -> data/vapid.json -> generated) and a pywebpush send helper that reports gone endpoints for pruning. No DB coupling. - notify.py: after creating an in-app Notification, dispatch Web Push to the user's devices (guarded — a push failure never affects the in-app write; endpoints reported gone are pruned). - Serve the .webmanifest with the correct media type. Frontend: - manifest.webmanifest + 192/maskable icons; <link rel="manifest"> on all pages. - sw.js: push + notificationclick handlers (push-only; no fetch caching, so it doesn't fight the existing IndexedDB cache). Registered globally in nav.js in secure contexts. - push-client.js + a "Notifications on this device" toggle and test-send on the /alerts page, subscribing through the existing cookie-aware apiFetch. Push and service workers require a secure context, so this is active over HTTPS (or http://localhost) and cleanly no-ops on a plain-HTTP LAN origin.

<h2>How the grades work</h2>
|
|
<p>Every grade is <b>relative to this place's own climate history</b>, not an absolute
|
|
temperature. For each day Thermograph builds a ±7-day seasonal distribution from
|
|
decades of local records, then reports the <b>percentile</b> where the day falls in it.</p>
|
|
<p>So a 60° day can be “Above Normal” in one place or season and
|
|
“Below Normal” in another. That's why the categories read
|
|
“Above/Below Normal”, “High/Low”, and “Near Record” —
|
|
never “hot” or “cold”.</p>

<h2>Rain intensity — percentile among rain days</h2>
|

<p class="muted">Precipitation is graded only across days that actually saw rain, so

their dry streak instead (below).</p>
