/* ==========================================================================
   Do Prompt à Produção — folha de estilo do deck
   ==========================================================================
   Herda o design system do portfólio (lucasvnd.github.io): dossiê técnico.
   Papel manila, tinta de arquivo, azul de assinatura, mono para
   identificadores, carimbo para veredito. Nada de neon, nada de capuz.

   O slide é um palco fixo de 1600x900. deck.js calcula a escala e aplica um
   transform. Assim a tipografia sai idêntica em qualquer projetor, e o CSS
   pode usar pixel sem medo.
