   PG ADVOGADOS — Base / Componentes da plataforma
   Os design tokens (variáveis --pg-*) moram em tokens.css (fonte única,
   também injetado nos dashboards do Firestore pelo backend). Este arquivo
   traz o reset e os componentes da plataforma (header, cards, tabelas…).
   Use SEMPRE as variáveis CSS. Não hardcode hex no HTML.
