/* Molt & Moss
   ---------------------------------------------------------------------------
   Botanical blackwater. Warm paper in light mode, tannin-stained brown-black in
   dark, moss green throughout. Those are the actual colours of a planted shrimp
   tank with almond leaves in it, which is the point.

   Deliberately avoided: left-border callout boxes, uppercase letterspaced micro
   labels, and flat neutral grey. Those read as template, not as a person who
   keeps tanks.

   Still no red or blue anywhere in the UI. Both are product colours, and a red
   button next to a Sunkist photo makes the shrimp look washed out. */
