/* mootrix.studio
 *
 * Black and white, because that is what the mascot is: a Holstein cow in a
 * dark suit and sunglasses. The palette is the LAUNCHER'S, value for value --
 * see moo/gui/theme.hpp, which carries the same reasoning.
 *
 * Both of them wore Wildeck's gold in a first draft, and both were wrong to.
 * The studio is not the card game; a site and a launcher that borrow a game's
 * colours are a site and a launcher that will look stale the day a second
 * title ships.
 *
 * The cast is very slightly COOL -- a couple of points of blue in the darks.
 * Neutral grey reads muddy; the cool tilt reads as night, chrome and glass,
 * which is the register the mascot is already in.
 *
 * The only chromatic values here cover a state dot and an error line. They are
 * held well back, the way a black-and-white film uses one red object.
 *
 * Plain CSS, no build step, no framework.
