   QUINTA DA CERCA DO COLÉGIO — Concept "Lisboa 1: Palácio & Património"

   DIRECÇÃO DE DESIGN
   Inspirado no Tivoli Palácio de Seteais e no Pestana Palace Lisboa
   (ver concepts/lisboa-research.md) — palácios do séc. XVIII/XIX
   com salões dourados, simetria clássica e jardins formais.
   Paleta verde-garrafa escuro + dourado envelhecido + creme/marfim.
   Tipografia muito serifada e em maiúsculas espaçadas, molduras finas
   a dourado, composições simétricas e cerimoniosas.
   Posicionamento emocional: "está a entrar num palácio com séculos
   de história, construído para momentos solenes e inesquecíveis."
