Weather
Weather is global environmental state rendered diegetically through Rooms.
A Room receives weather prose only when its outside flag is true.
Weather output also respects perception: visual and auditory observations
disappear when those senses are unavailable, while other applicable sensory
observations can remain.
Builders can mark a room exposed with:
@room/outside on
Staff with the weather command can inspect or change the global state:
@weather
@weather list
@weather clear
Changing global weather affects outdoor Rooms; it does not rewrite their
authored descriptions.
