   tech.css — tema das páginas de tecnologia (categoria, série, livros)

   A página tem a cara do que ensina: fundo de editor, tipografia de terminal,
   código de verdade tirado do livro e o letreiro "One" das capas. As cores
   vêm de cada livro (catalogo.yaml → cores) pelas variáveis:
     --acento  --acento-claro  --fundo  --painel  --papel
