   himal · हिमाल — companion site design system
   The language is borrowed from the game's own interface (drawn from
   Newar sources: a paubha's madder, ink, gold and cloth; a temple
   cornice's pendant fringe) softened by the Himal design-harness
   direction: cream, lowercase, quiet rounded list cards.
