/* ===================================================================
   GAMBIT Lab additions on top of the MindHaven skeleton.
   The template's stock photography (SaaS UI mockups with fabricated
   names, generic classroom/student stock photos) is not reused here
   since none of it truthfully represents the lab. These rules replace
   those image slots with icon/gradient/avatar treatments built from
   the template's own --primary/--secondary/--tertiary/--quinary
   palette, without altering the section skeleton itself.
