/* ==========================================================================
   Dinâmica Serviços Administrativos — estilos
   Direção: "instrumento preciso" — tinta escura, papel claro, azul de sinal
   reservado à ação, dados em mono tabular. Contrastes medidos em docs/DESIGN.md

   Regra de layout: as seções que os botões do cabeçalho abrem (Sobre,
   Serviços, Como trabalhamos, Contato) cabem INTEIRAS numa tela (100svh).
   Tipos e espaços usam unidades de largura E de altura, e cada formato de
   aparelho tem um arranjo próprio (carrossel de serviços no celular…).
   O site.js confere se coube; se faltar pouco, reduz a escala da seção em até
   20%. Se faltar mais (ex.: zoom do navegador em 200%), nada é reduzido — o
   zoom escolhido pela pessoa vale mais que o encaixe.
   A rolagem é livre, com as animações de sempre.
