   Diego Carvalho — portfólio. Folha compartilhada.

   Estilo: caderno de engenharia. Papel quente, tinta quase preta, display em
   Fraunces, corpo em IBM Plex Sans, rótulos/chips em IBM Plex Mono. A única
   cor é o acento de cada projeto. Registro técnico, não de venda.

   O motor de scroll (scrub-engine.js) injeta o próprio CSS em @layer sw e lê
   as vars --sw-*. Nada aqui usa o prefixo .sw- além do tema em .sw-root.
