 * Site público da VinCore — tema da V2 (site-vincore.md §3), aprovado pelo André em 2026-10-20 a partir da prancheta
 * https://claude.ai/artifact/RBwr9bFb3qBeGJv1dNUW58. A direção C (editorial: papel claro, faixas marinho, Unbounded nos
 * títulos e Onest no texto) com as animações da direção A — os anéis orbitando o logo como animação principal, os canais
 * fluindo até o núcleo, a pílula que desliza no menu e a barra de progresso, a luz que segue o cursor, a conversa que
 * acontece ao aparecer e a borda girando na chamada final.
 * CSP style-src 'self': todo estilo mora aqui — nenhum atributo style no HTML. Os atrasos de animação são classes
 * (.d1–.d4, .n0–.n5, .w2–.w4), não variáveis escritas no HTML.
 * Com "reduzir movimento" ligado no sistema da pessoa, nada se mexe (fim do arquivo).
