# Стартовая комната: ничего тяжёлого, только пол, стены и порталы на карты. Сами карты качаются
# отдельными пакетами при входе в портал (World/map_loader.gd) — поэтому игра стартует быстро.
# Чтобы добавить карту — допиши запись в PORTALS: порталы встанут в ряд по центру (влезает 7).
# Оформление (колонны, окна, голограмма, лавки) — hub_decor.gd; музыка «как в лифте» играет по кругу.
