   Água Boa Poços Artesianos — Tatuí/SP
   As cores saem da logo, medidas no arquivo: azul #3678BA da gota e do "BOA",
   navy #243C54 do "ÁGUA" e do "POÇOS ARTESIANOS". O navy carrega as seções
   escuras, o azul é o destaque e o gelo é o descanso entre elas.
   Mobile primeiro: uma coluna, botão grande e o WhatsApp sempre alcançável.
