   Pasts A — "Pastkaste". Rail, list, reading pane.

   Same tokens as Zvani A: if an owner picks both, they have to look like one
   product rather than two tools bought from different people. The only thing
   here that is not a mailbox is the drafted reply — so it is the only element
   allowed to draw attention to itself.
