/* Bopcat video maker: token system.

   Every color comes from Bopcat's own material, none invented:
   - plum scale: the token art's background family
   - mauve: the cat's body color
   - cream: the pale rim of the cat's eyes
   - chroma: the official green-screen clip's key color; reserved for the
     one action that "puts you inside the edit" (render, drop target)
   Type: Knewave is the display face the project's own site used; body is
   the system stack; utility is the system mono for small working labels. */
