/* h3-studio — tema custom.
   Inspirado no visual do Linear (linear.app): fundo quase preto levemente
   azulado, bordas de baixíssimo contraste, um único acento frio, tipografia
   Inter com tracking negativo nos títulos, e cantos generosos.
   Sem framework: o site tem três páginas e roda numa e2-micro de 0,25 vCPU —
   um CSS de 6 KB entrega o mesmo e não custa um build. */
