/* ===========================================================================
   Mensch Lab — /lab and /lab/<study>

   Two surfaces share this sheet:
     1. /lab            the index: LAB spinner, filters, study/tool cards
     2. /lab/<study>    a single-viewport, game-menu style research page

   Everything here leans on tokens.css. No new colours are invented; the two
   studies differ only by --study-accent, set per page.
