   Mars Market — main.css
   A dark, terminal-adjacent editorial layout. One content width is shared by
   the header, nav, breadcrumbs, main and footer so everything lines up.
   Palette: near-black neutrals + a single purple accent (from the brand mark).
   Type: IBM Plex Mono for display/labels/addresses, system sans for body.
