/* Surfaces. A card exists only when the content needs a boundary (a form, a table,
   one item in a set). Never nest cards: inside a card, use rules and spacing.
   .card        lacquered panel: bevel, the window frame tint, soft shadow (V2-SHELL: tight corners).
                Data groups use .window (css/components/window.css); a card is for a form or one item.
   .panel       same surface, tighter padding, for items in a grid
   .card-link   a card that is one big link: lifts on hover
   .account-bar the signed-in/out strip above shop and exchange */
