   Este é o ÚNICO arquivo de estilo do site. Para mudar a aparência de
   TODAS as páginas, edite as variáveis em :root (cores, fontes, raios,
   sombras) — tudo abaixo deriva delas.

   Base: a página /psicoterapia/. Estende-se com todos os componentes
   usados nas demais páginas (heróis, cards de serviço com imagem, listas
   de materiais, grades de vídeo, player de rádio, seção de app, etc.),
   todos re-coloridos com a mesma identidade.
