/* ==========================================================================
   MERITALIEN FRONTIER — the referral network page

   One idea for the page: a network is a picture of people who know each other,
   so the hero draws one instead of borrowing a stock photograph of a handshake.
   The constellation is generated (deterministic seed) in build.py, so it is the
   same picture on every build and the OG card cannot drift from the page.

   Accent discipline: --accent appears on the hub nodes and the primary CTA and
   nowhere else on this page. The hubs ARE the "go" of the illustration.
