/*
 * 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').
 * renderer      - Background renderer: 'vanta' (default, GPU 3D volumetric
 *                 raymarched clouds via three.js), 'clouds2d' (lightweight
 *                 WebGL fragment shader, 2D fBm scrolling), or 'clouds3d'
 *                 (volumetric raymarcher with camera fly-through).
 * 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.
 * 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).
 *
 * 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
