/*
|
||
* Wallpaper background config.
|
||
*
|
||
* Properties:
|
||
* theme - Active palette theme. One of the keys in window.THEMES
|
||
* (default 'ash'). The matching CSS file is loaded at
|
||
* startup.
|
||
* language - UI / i18n language code (default 'en').
|
||
* timeFormat - Moment.js-compatible format string for the clock.
|
||
* debug - If 1, the right-side debug panel is shown.
|
||
* units - Object with 'temperature' ('C' or 'F').
|
||
* location - Geographic coordinates for sun/moon calculations. Used
|
||
* by SunCalc (https://github.com/mourner/suncalc). Object
|
||
* with 'lat' (latitude, -90 to +90) and 'lon' (longitude,
|
||
* -180 to +180). Positive lat = north, positive lon = east.
|
||
* Optionally add 'label' (string) to override the
|
||
* reverse-geocoded city name.
|
||
* Note: the height grid is axis-aligned (N up); terrain
|
||
* matches the 8-mode square mosaic and straight flights
|
||
* with fetch=N. Heights: Copernicus DEM via terrarium
|
||
* tiles (z9, ~200 m), fetched once per session.
|
||
* terrain - 3D ground from real elevation data. Object:
|
||
* enabled - true (default) / false = flat plane.
|
||
* exaggeration - vertical scale factor on the DEM
|
||
* (default 8; 1 would be physically
|
||
* true and nearly invisible at this
|
||
* horizontal scale).
|
||
* weatherSim - If true, ignore open-meteo and cycle through
|
||
* ['sunny','cloudy','stormy','night'] automatically every
|
||
* weatherSimInterval ms. Useful for A/B testing every
|
||
* theme without waiting on the API.
|
||
* weatherSimInterval - Sim cycle period in ms (default 30000).
|
||
* orbit - Figure-eight flight (Bernoulli lemniscate) around
|
||
* CONFIG.location instead of a straight drift. The
|
||
* eight's self-crossing sits exactly on the configured
|
||
* coordinate. Each time the aircraft crosses that point
|
||
* a new random orientation is picked and blended in
|
||
* over one lobe (spline through the crossing). Object:
|
||
* radiusKm - lobe tip reach from the centre in km
|
||
* (~13 km per tile at z11/48deg N).
|
||
* Clamped (~190 km) so tips + fog horizon
|
||
* fit inside the 43x43 tile mosaic.
|
||
* clockwise - travel direction along the eight.
|
||
* reorient - random re-aim at every crossing
|
||
* (default true; false keeps the bearing).
|
||
* Set to null (or remove) for the straight-line flight.
|
||
* fog - Ground fog / distance haze. Object with 'distanceKm'
|
||
* (visibility range at which terrain fully blends into
|
||
* a milky haze; default 120). false/0 disables fog.
|
||
* clouds - Vertical extent of the cloud deck in world units
|
||
* (1 unit = ~13 km at zoom 11; camera flies at y=2.2).
|
||
* Object with 'top' and 'bottom'. Default keeps the
|
||
* deck a bit below flight altitude.
|
||
* tiles - All downloads (street tiles, elevation grid, last
|
||
* weather payload, geo label) live permanently in
|
||
* IndexedDB and are never re-fetched once cached; a
|
||
* warm cache = fully offline rendering. Set
|
||
* expireDays (number > 0) to re-fetch street tiles
|
||
* periodically (e.g. 90).
|
||
*
|
||
* Time format tokens (subset):
|
||
* YYYY 4-digit year (2026)
|
||
* YY 2-digit year (26)
|
||
* MMMM full month name (October)
|
||
* MM month with leading zero (10)
|
||
* DD day with leading zero (07)
|
||
* HH 24-hour hour with zero (18)
|
||
* hh 12-hour hour with zero (06)
|
||
* mm minute with leading zero (14)
|
||
* ss second with leading zero (25)
|
||
* a am/pm lowercase (pm) - long form
|
||
* A AM/PM uppercase (PM) - long form
