   MÉTODO HAG — Design System v2 · "Luxo Tech Monocromático"
   Site institucional · Dr. Henrique Alves Gonzaga · CRM/SP 226530
   ---------------------------------------------------------------------
   Identidade: monocromática (grafite), alto contraste controlado.
   O acento é o próprio grafite — sem cor saturada.
   Tipografia: Space Grotesk (display) · IBM Plex Sans (corpo) ·
   IBM Plex Mono (labels/eyebrows/números). Carregadas via <link> no HTML.

   PILOTO: por enquanto só a index.html usa esta folha. As demais páginas
   seguem em assets/css/styles.css até a propagação.
