   Identity: ledger paper and brass. The product sits between a pawn counter and
   a database, so the palette borrows from both — warm paper stock, a brass
   accent for the thing being weighed, and a clear red/teal split for the one
   idea the product turns on: what the model proposes versus what our code
   permits. Deliberately not the blue-purple gradient every AI product wears. */
