/* ==========================================================================
   SDG — Design System
   Font pairing: Sora (display/headings) + Manrope (body) — self-hosted,
   inspired by the MAIKER HUB reference for typographic confidence, not copied.
   Color: anchored to SDG's real brand teal-blue (#0b3c4d / #136480 / #1a8bb3 / #00a0d1),
   modernized with a near-black navy for contrast sections.
