/* PRFKT OS 6.0 "Big Bear" (bigbear.js): the desk behaves like a modern desktop OS while keeping the paper, ink and lime skin.
   Menu bar with real pull-downs (shortcuts right-aligned, separators, submenus), lamps and a clock on the right; a dock with
   magnification, bounce and running dots; traffic-light window controls on a pinstriped title bar; window snapping; the Apps grid;
   the notification centre; About, Welcome and Quick Look cards; hot corners; the living desk. Mac-inspired, never Mac-named.
   Tokens from site.css; motion follows html[data-motion] (prefs.js) and the device. */
