   CONCEITO.CSS — Jonathan de Carvalho e Camila Henn
   Cirurgiões Dentistas · Nonoai, Porto Alegre – RS

   Paleta: azul-marinha profunda + branco-gelo + azul-vivo (destaque).
   Derivada da identidade do nicho: confiança, clareza, saúde, limpeza.
   Distinta de: bronze (Living), oliva (Flávia), terracota (futura Dentistas e Cia).

   Fontes: DM Serif Display (display, serifado moderno, não editorial pesado)
           + DM Sans (corpo, geométrica clean, leitura confortável).
   Par próprio, não usado nos sites anteriores do lote.

   Grande Ideia: "O dentista que não deixa você sair com dúvida."
