/* ==========================================================================
   Heart + Knowledge for Community Work — Part 2
   Non-profit Leadership and Governance Conference, Aruba, 31 October 2026

   Palette and type are taken from the conference collateral: the ground is the
   blue of the ballroom the conference is held in, the primary is PANTONE 320 C
   (named in the HKC logo artwork), and the accent is the far end of the teal →
   coral gradient used on the invitation.
