   GLADD Onboarding LP — shared styles
   Design brief (2026-07-10 mtg): standard top-to-bottom,
   single column flow, mobile-first, 40代以上が読みやすい。
   Responsive: prose stays a readable measure; card/stat/reason
   rows become multi-column grids on tablet / PC.
   Brand: #D8273C (GLADD red) + white.
