   image-kit.css — shared look for the Hub's image tools.

   Only the newer image tools link this. The older ones inline their
   own copies of these rules; hub/_headers serves assets `immutable`,
   so folding them in would mean bumping ?v= on every page. Nothing in
   here redefines a hub.css token — it only composes them.
