/* ==========================================================================
   Tens Games — shared styles, built on the Tensflare design system v2.
   Warm black surfaces, cream type, sans 500 headings, mono uppercase labels,
   6px radii. Products carry their own colour as a thin bar or badge; the
   studio pages themselves stay monochrome. The mark appears once, in the nav.
