   SYNAPSIS — TOKENS BASE (partilhado por todas as páginas)
   Fonte de verdade: Design System "Synapsis" (tokens.json).
   Para mudar de paleta basta alterar o atributo no <html>:
     <html lang="pt-PT" data-tema="azulejo">   (por defeito)
     <html lang="pt-PT" data-tema="ameixa">
     <html lang="pt-PT" data-tema="pinhal">
   Só mudam --accent, --accent-hover e --accent-tint.
   Regra: o accent é só de interface; nunca é cor de série num gráfico.
