/* The Arena marketplace page (arena-marketplace.html). Dense, dark listing
   cards in the spirit of exchange copy-trading marketplaces: a big return
   figure, the record's curve, three stats and one button; a side drawer for
   the details. The look in docs/ARENA-SITE-SPEC.md ("Look"): 1px borders,
   tabular numbers, one violet accent, green/red only for gains and losses.
   Loaded last, on this page only; everything is prefixed mk- and scoped to main.mk. */
