/* ============================================================
   NÁUTILUS — hoja de estilos
   Dirección: costa/naturaleza. Sand + laguna teal + coral de acento.
   Señal propia: la retícula de "plano de lotificación" como motivo
   recurrente (líneas finas, marcas de agrimensor) — es literalmente
   lo que Náutilus vende: terreno medido, ordenado, tuyo.
