Reuses the saved weather location's lat/lon to fetch us_aqi from
Open-Meteo's air-quality API (no key), folded into the existing 2h
forecast cache (bumped v1->v2). AQI is best-effort: a failed fetch
never sinks the forecast. Shows as a header chip and a colored row
on the forecast card; both self-hide when there is no reading.
Signed-in users get their preferences (hidden feeds, weather location,
weather toggle) stored server-side keyed by their OIDC subject and synced
across devices. Anonymous visitors keep using browser localStorage, so the
site stays public. First sign-in migrates existing localStorage prefs up.
- config: [web.auth] section (issuer, client_id/secret, redirect, session_secret)
- storage: user_preferences table + Get/PutUserPrefs
- web/auth: OIDC code flow, HMAC-signed session cookie, CSRF state + nonce
- web/prefs_api: GET/PUT /api/preferences (auth-gated, 64KB cap)
- frontend: prefs.js sync layer seeds localStorage from server, pushes on write
- header: sign-in / account control
OIDC discovery is non-fatal at boot: if Authentik is down, Pete serves
anonymously rather than refusing to start.
Visitors can save a postal code (international, via Zippopotam) to get the
local forecast from Open-Meteo — a header chip + a 5-day home-page card —
and the canvas background switches from the seasonal effect to live
conditions. Entirely client-side: no keys, no server logic. Geocode cached
permanently, forecast cached 2h. Celsius by default, Fahrenheit opt-in.
New canvas effects: clear (sun by day, shaded moon + stars at night),
clouds (blurred drifting sprites), snow, fog, and storm (rain + lightning).
Seasonal effects remain the no-location fallback.
