A mobile layout for the gift chooser, and Q-006 closed as a decision.

Changed

• The gift chooser is compact on phones. Below 600px the card grid fell to
  a single column, so every option became a full-width product image and a
  handful of gifts pushed the customer's own cart lines several screens down.
  Each card is now a cart-line-shaped row — 64px thumbnail, name and price
  beside it, button underneath. Six gifts now take about one screen instead of
  four. Nothing changes at wider widths, and the change is CSS only, so the
  classic cart, the block cart, and checkout all get it from the same rule.

• A reward of a product already in the cart keeps its own line
  (OPEN-QUESTIONS.md Q-006, now DECISION.md D-020). This is what the plugin
  has always done and it is now a decision rather than an assumption, with tests
  behind it: the two lines carry different prices, so one merged line could not
  show the customer which unit was free or discounted.
