/* ==========================================================================
   Inspired Air Fund
   Design system derived from "Inspired Air Fund Concepts 04" (Aug 7, 2026),
   design direction: Waves.

   Palette and type are taken directly from the deck:
     - colours sampled from the vector fills on the CORE ELEMENTS page
     - Domus Titling is the logo face (shipped as extracted vector art, so no
       webfont licence is required); Red Hat is the interface face
