   Sakura. Where the reference sets forest green on beige, this sets
   bark on blossom: the light ground is the white at a petal's edge
   with the pink it picks up where petals overlap, and the dark bands
   are the plum-black of a cherry trunk in rain: not a neutral dark.
   Every grey here carries the same pink bias, on purpose.

   here and nothing else anywhere.
