 *
 *   SITE KIT — marketing surface (este projeto)
 *
 * ══════════════════════════════════════════════════════════════════════════
 *
 * Estende os primitivos de `../tokens.css` com vocabulário do SITE:
 *   • Layout (container, section padding)
 *   • Type scale de marketing (hero gigante, display, body 15px)
 *   • Componentes utilitários (.site-button, .site-pill, .site-eyebrow, .site-card)
 *   • Chrome (skip link, splash loader)
 *
 * NÃO confundir com kits/hub.css (que vive em outro projeto) — esse define
 * vocabulário de SaaS (sidebar, drawer, command palette, etc).
 *
 * ORDEM DE IMPORT (em todas as páginas HTML do site):
 *   <link rel="stylesheet" href="<ROOT>/ds/tokens.css">
 *   <link rel="stylesheet" href="<ROOT>/ds/kits/site.css">
 *   <link rel="stylesheet" href="<ROOT>/ds/mobile.css">
 *
 * VERSÃO: 1.0.0 — 2026-05-19
