/* Badges, floating (badge-float.js). The stage is a wide strip on laptops
   and a 4:5 frame on phones; each badge carries its own place and tilt for
   both as custom properties:
     --x --y --r    wide: centre (% of the stage) and tilt
     --px --py --pr phone
     --w --pw       width, % of the stage
     --ar           the art's width / height
   Everything inside a badge is sized to the badge (container units), so it
   scales as one piece. */
