/* =====================================================================
   Design system do Cadu — tokens, tipografia e base compartilhados.
   Carregado por todas as páginas (site React e /calculadoras/).
   Fonte única de cores, fontes, botões, cabeçalho e rótulos.

   Paleta da marca (prancha do Instagram):
     #5B8DEF azul   · confiança        #34C38F verde · clareza
     #FFC857 amarelo · energia/destaque #FF8B88 coral · acolhimento
     #3D3D3D texto  · #F6EFE6 fundo
   Os tons "-ink", "-tint" e "-soft" são derivados da paleta para texto
   (contraste AA) e fundos suaves. Nunca use o azul puro para texto pequeno.
