   Givewell Volunteer Platform — cohesive mobile-first stylesheet
   Aesthetic: vibrant, joyful, "civic sunrise". A high-energy palette of coral,
   tangerine, magenta and electric violet, balanced by a jade success tone, on
   a bright warm-white canvas lit by aurora gradient glows. Editorial display
   serif paired with a humanist sans. Generous tap targets, layered soft
   shadows, gentle grain. Built to feel alive and invite participation.
