Identity and price selection

Keep each selection explicit.

Keep a card’s identity distinct from the price lane you ask for.

  1. 01
    Product identity

    Game, set, collector number, and verified printing identify a raw card.

  2. 02
    Variant + condition

    They select a price lane; they do not create a new card identity.

  3. 03
    Price context

    Integer USD cents, an explicit currency, and a price_updated_at timestamp stay visible.
