/*
 * iFunnel — the application root.
 *
 * This page has no call to action, because there is nothing here to act on: a
 * funnel is reachable only by the link its organiser shared, and there is no
 * public listing of them. So the layout leads with the tagline and hands over the
 * one fact a stray visitor needs — the shape of a funnel's link.
 *
 * Amber appears exactly twice, mirroring the single amber card leaving the logo:
 * on the link's slug segment, and on `Curated`, the only stage that is an outcome.
 * Amber *text* uses --color-warning rather than the logo's lighter #EDB35F, which
 * does not carry enough contrast on the light ground.
