/* LinguistDesk design tokens and the shared components' styles (LingoDesk.UI).
   SKINS (html[data-skin]): porcelain (default - warm white, emerald), evergreen (light pages, deep green menu),
   midnight (dark), system (porcelain or midnight, following the device). Every colour below is a token, so a skin is
   only a block of tokens. Layout: a left rail for the app, one content column; cards only for separate objects. */
