/* The anonymous MERIDIAN landing.
 *
 * This page's job is to say almost nothing. It ships no product screenshots, no feature copy,
 * no pricing, and no navigation — the sign-in control is the only way forward, and everything
 * MERIDIAN actually does lives behind it (/welcome). Keep this file small and self-contained:
 * the 95 KB marketing stylesheet it replaced pulled a whole design system onto a page that
 * renders eight elements, and every class it carried was a hint about the product.
 *
 * CSP is style-src 'self' — no inline styles anywhere, here or in the HTML.
