/* Market Activity (/market/activity).

/* The shared layout gives <main> 2.5rem of top padding and the breadcrumb another 1rem beneath
   it, which on this page left ~90px of empty band between the site header and the first thing
   worth reading and pushed the opening row of prices below the fold on a 768px-tall laptop.
   Scoped with :has() to this page's own wrapper rather than changed in the shared layout, so no
   other screen's rhythm moves; a browser without :has() simply keeps the old spacing. */
