-  This partial expects:
-    - cards: a list of card objects
-    - mode: a string that determines the render style.
-      It should be "offered" for Most Offered Cards and "wanted" for Most Wanted Cards.
-    - Optional:
-        'show_zero' flag (default False): if True, also display cards with 0 offers.
-        'layout' variable: if set to "auto", use an auto-fit grid based on available horizontal space.
