  Paleta e tokens:
    - Gradiente de fundo: var(--bg-top) → var(--bg-bottom)
    - Cartões: var(--card-bg), sombra var(--card-shadow), raio var(--card-radius)
    - Botões pílula: gradiente var(--btn-start) → var(--btn-end)

  Convenções:
    - Layout em 3 etapas com cartões (.card)
    - Estados de UI via classes utilitárias (.hidden, .state)
    - Componentes principais: .pill-button, .input, .results-list, .details

  Acessibilidade:
    - Foco visível em inputs
    - Contraste em títulos e estados
