   CharityCareCheck.com — Shared Stylesheet
   A calm, ledger-inspired design system for a hospital financial-assistance
   reference site. Built around a paper/forest/amber palette, a serif+sans+
   mono type system, and hairline "statement line" dividers that echo the
   subject matter (billing statements, eligibility thresholds).
