/* Plenário Slides · galeria de apresentações.
   Reproduz o visual de felipelamarca.com (felipelmc.github.io): tokens de src/styles/global.css,
   cabeçalho de Header.astro, títulos de seção de SectionHeader.astro, cards de ProjectCard.astro
   e rodapé de Footer.astro. O tema claro/escuro usa a mesma chave (localStorage.theme) e a
   mesma classe (.dark) do site, então a escolha vale nos dois. */
