   DESK TO DIVA — tools layer
   Styles for the three interactive tools:
     .finder  — shade & style finder quiz      (finder.html)
     .sizer   — coin-calibrated nail sizer     (size-guide.html)
     .looks   — pin & compare tray             (custom.html, shop.html)

   Loaded only on the pages that use them. Uses the existing tokens
