/* polar.css — Polar Ice Guayaquil · diseño "Elegante" en azul marino (23-oct-2026).
   Todo azul marino, muy poco blanco, un solo azul hielo de acento. Inter Tight / Instrument Serif / Inter.
   Los nombres de variables (--ivory, --paper…) se conservan; ahora son tonos de azul marino.
   Una sola hoja para todas las páginas; Ártico usa chat.css. Los efectos de movimiento viven al final de main.js. */
