/* Pidgin. Two inks, one container, whole pixels.
   Paper #F2EFE6, ink #111111, nothing else.
   Type scale 16 / 20 / 24 / 32 / 48 (the kit's floor is 16 px, so 12 and 14 are not used).
   Spacing scale 4 / 8 / 12 / 16 / 24 / 32 / 48.
   Every pixel object (wordmark, cards, stamps, objects, wall) is sized in JS to a whole number of DEVICE pixels per
   art pixel (js/px.js), so it stays sharp at 100%, 125% and 150% Windows scaling. */
