/**
 * Tutorial · CSS específico do CPT `tutorial`.
 *
 * Premissas:
 *   1. Container e max-width vêm de .zigg-article (definido em article.css).
 *      NÃO redefinir aqui.
 *   2. Componentes compartilhados (.zigg-breadcrumb, .dl-pre-comments-ad,
 *      .dl-editor, .dl-comments) estão em assets/css/components/singles.css.
 *   3. Foco em LEITURA: tipografia confortável, sem decorações excessivas,
 *      hierarquia clara entre H1/H2/H3, listas e imagens.
 *   4. Sidebar à direita no desktop (≥1100px), abaixo do conteúdo no mobile.
 *   5. Reutiliza tokens globais (--paper, --ink, --ember, --f-*).
 *
 * Carregado condicionalmente via inc/enqueue.php quando is_singular('tutorial').
