/*
 * GHI public site — the apex domain's front page.
 *
 * A deliberately separate surface from the Harmonica app (app.<domain>):
 * its own fonts (Cormorant Garamond for display, Manrope for text), its own
 * navy/gold palette, no framework. The app's "Inter only" rule does not
 * apply here, and nothing here may be imported into the app.
 *
 * Ported from the client's design prototype; class names match it so the two
 * can be compared side by side.
