Rain mode with canvas rain, stormy sky, sun-to-moon transition and
lightning strobe. Mode switching fixed so only one of moon/globe shows:
file pollers are edge-triggered (stale /tmp files no longer fight),
toggle scripts keep the files mutually exclusive, exits fade fast while
entrances stay slow, drawGlobe solely owns globe opacity, and leaving
chuva restores the album-color theme on fog/horizon.
