/* /public/lib/explainer.css
   Marketing Engine — reusable "?" explainer modal styles.
   Loaded once per page; the engine auto-attaches to every .explain-trigger,
   including triggers injected after a fetch.

   Mission Metrics™ palette (brands/mission-metrics-solutions/brand.json):
     primary      #1EB980   Impact Green
     primaryDark  #17A06D
     dark         #0B2343   Deep Navy
     light        #F4F7FA   Cloud
   Host-page variables (--green / --navy / --cloud, as studio.html defines them)
   win when present, so the modal always matches the page it opens on.
