/* Ambient background gadget (assets/js/gadgets/ambient.js): one fixed WebGL
   canvas behind the whole page. Dark theme draws a slow aurora and a field of
   parallax stars; light theme draws faint pink cumulus. Rendered at half (or
   quarter) resolution and upscaled here; fades in after the first frame. */
