 * Design thesis: COLOR MEANS CHAOS.
 * The base game is calm ink and one trustworthy blue on cool paper. The sly
 * magenta (--mischief) is reserved exclusively for the moment a troll acts, so
 * players learn the tell: magenta = something shady just happened. The polish
 * is the setup; the magenta is the punchline.

     - Auto (no data-theme attribute): follow the device via the media query.
     - Forced Day  (data-theme="light"): light values win, even on a dark device.
     - Forced Night(data-theme="dark"): dark values, even on a light device.
   Devices with no dark-mode concept never match the media query, so they stay
