   Buscador de Imóveis — design system compartilhado
   ═══════════════════════════════════════════════════════════════
   Padrões aplicados (research 2026 SaaS UX):
   - Foco em métricas: números grandes com hierarquia forte
   - Progressive disclosure: mostrar essencial primeiro
   - Skeleton loading em vez de spinners genéricos
   - Densidade moderada — nem overcrowded nem esparso
   - Microinterações rápidas (120-200ms) que dão feedback tátil
   - Empty states que orientam próximo passo
   - Tipografia system + hierarchy clara
