/* SOS Limpeza e Manutenção de Piscinas — landing única (pacote LP 999).
   Paleta de piscina: azul profundo do fundo da água, turquesa da lâmina,
   areia do deck. Sem framework e sem build: um CSS, um JS, arquivos estáticos.

   Contraste: --pool (#0e7f9e) tem 3.6:1 sobre branco, o que serve para
   preenchimento e borda, mas NAO para texto. Texto em azul usa --accent
   (#0a6683, 5.2:1). Se trocar uma cor, verifique antes de aplicar em texto. */
