/* ============================================================================
   careonomy.com — Baseline Stylesheet
   ----------------------------------------------------------------------------
   The operating-partnership site for Care OS™. Built by Caryfy AI.

   Palette: Operating Partnership
   - Forest green primary (operations expertise + sustainable partnership)
   - Warm ivory paper (ecosystem tie to careos.ai)
   - Copper accent (ecosystem tie to CareBravo)
   Distinctive from both careos.ai (navy/cream) and CareBravo (ink/copper/teal),
   yet visually coherent with the wider Caryfy AI ecosystem.

   Typography:
   - Display: Fraunces (family consistency with careos.ai)
   - Body: Inter (slightly warmer than Inter Tight; appropriate for
     consulting-register longer-form pages)
