/* Kiki Estúdio · site institucional (v3)
   Leitura: estúdio pequeno de serviços digitais para profissionais liberais (psicólogas no começo da carreira).
   Referências da Lane: Pinkers (menu flutuante em pílula, cor só em pontos estratégicos, logo gigante no rodapé)
   e WizardZ (minimalista, ilustração de traço preto, destaque de texto).
   Dials: VARIANCE 7, MOTION 5, DENSITY 3. CSS nativo, sem biblioteca.
   Estrutura: seções em largura total, alternando fundo. O arredondado fica no menu, nos cartões, nos botões
   e numa curva só no topo de três seções (Como funciona, Contato, Rodapé).
   Cor: neutros + um acento coral, usado no destaque dos títulos, nas ilustrações e no bloco de contato.
   Tema: claro fixo (as ilustrações são traço preto sobre claro, como nas referências). */
