/* The one page with a marketing job.
 *
 * It sells a single idea — one agent, and every capability the company has
 * built sits behind it — so the page is built to look like the product rather
 * than like an advert for it. Same tokens, same hairlines, same type scale as
 * the chat; the hero's centrepiece is the composer itself.
 *
 * Two things here are not the chat's: the hero is a dark band over an animated
 * mesh gradient (static/Gradient.js, the engine the first landing page used),
 * and the nav rides on top of it rather than sticking. Everything below the
 * hero is the chat's own surface, which is why the sections read in tokens —
 * the page follows the theme into dark mode instead of pinning itself light.
