  "directAnswer": "Choose Sintra for palaces and gardens, Cascais for coast and a looser day, or stay in Lisbon when the trip is short or the weather makes an excursion less rewarding.",
  "inputs": ["full days", "main interest", "expected weather", "preferred morning pace"],
  "outputs": ["recommended destination", "reason", "tradeoff", "next booking action"],
  "method": "The chooser weighs trip length, interest, weather and willingness to start early. Short city stays favor Lisbon; palaces and an early start favor Sintra; coast and flexibility favor Cascais.",
