   Chokhu mini-app

   Two surfaces, not one. The feed is black edge to edge because video decides
   its own colour and any chrome has to get out of the way; the inbox and the
   profile are light, the way every short-video app builds them, because a list
   of names read on a black background is a worse list. The wallet's yellow
   appears nowhere — a partner owns its own surface, which is the same point
   Bun Adda's cream makes from the other direction.
