/*
 * Home (index.html) — nova landing (#184), portada de docs/artifacts/2026-09-27-nova-lp.dc.html.
 * O layout de cada bloco vive nos atributos style do mockup (a CSP permite 'unsafe-inline' em
 * style-src); aqui ficam os tokens que o styles.css não tem, os componentes do design system
 * (Button, Badge, Pill), os estados interativos e o que no mockup dependia de JS (largura).
