The background weather is now GPU-rendered: one instanced-quad draw call
over a baked sprite atlas plus a fullscreen sky shader (fog, Saharan
haze, aurora, sun rays, storm gloom and lightning flash). The old
Canvas2D renderer stays as weather-2d.js and kicks in automatically
when WebGL2 is missing; weather.js is now a thin controller that owns
the toggle, prefs and the PeteWeather API.
Effect upgrades: shared wind with gust pulses leans the whole scene
together, rain gets depth, splash pops and velocity-aligned streaks,
storms grow procedural branched lightning bolts, snow mixes soft motes
with spinning six-arm crystals, clouds drift in two parallax layers,
clear nights get a moon with maria, twinkling stars and the occasional
shooting star, blossoms and leaves tumble with a faked 3D flip.
New variants: haze (Saharan calima), wind (autumn gusts with streak
lines), hail (bouncing stones with drizzle) and aurora. The /weather
demo page switches variant, intensity and phase in place without a
reload and shows the active renderer plus an FPS meter.
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.
Server picks variant from Lisbon-local date (rain/petals/jacaranda/motes/leaves)
and renders behind content via a canvas particle layer. Each variant has a
hand-drawn silhouette so shapes are recognizable. /weather demo route exposes
variant + intensity + phase pickers, locking the time-of-day phase override.
