/* Agent Mesh early access page.
 *
 * Visual system is inherited from the Forge homepage: paper and ink, one orange
 * accent, Fraunces for display, Geist for text, JetBrains Mono for labels. A visitor
 * arriving from theforge.ventures should not feel a seam.
 *
 * Three things this file does on purpose:
 *
 * 1. Every illustration is HTML and CSS, not an image. The hero scene and the
 *    three-layer diagram recompose from rows into columns at the breakpoint, the
 *    text stays real text, and a screen reader reads it in order.
 * 2. Nothing animates that a reader has to wait for. The one moving thing is the
 *    status dot, and it stops under prefers-reduced-motion. The hero's three steps
 *    are radio buttons: pure CSS, keyboard native, no JavaScript involved.
 * 3. Nothing here is loaded from a third party except the three webfonts, which the
 *    footer discloses, because the page promises the visitor it runs no analytics and
 *    it should not be quietly contradicted by its own asset list.
 *
 * Two colours differ from the Forge home on purpose. Small text uses a darker fade
 * (#736e65 rather than #8a857c) and small labels use the deep orange, because the
 * bright accent and the light fade both fall under 4.5:1 against paper at label sizes.
 *
 * One colour means one thing across the page: green is "in the beta", the wine red is
 * "planned" or "denied", and orange is the accent for what the reader acts on. A dashed
 * border always means "not built".
