/**
 * P17-E1 Bloco B — BLOG DESIGN SYSTEM V2 (camada central do blog).
 * Reusa os tokens de foxshop.css (--fx-*). Direção: tech-premium minimalista,
 * biohacking clean, azul #1266EC, hierarquia forte, muito respiro, sem carnaval.
 * Cobre o padrão global do artigo: H1/H2/H3, parágrafos, listas, tabelas,
 * links, blockquote, referências, callouts, banners, spacing e mobile.
 * Sem inline styles espalhados, sem depender de Tailwind arbitrário inexistente
 * no build (valores entre colchetes ficam inertes — lição P17-R4), sem glass,
 * sem sombra pesada, sem alterar UMA vírgula do texto do artigo.
