"""Bundled station, so a cold offline start still makes sense.

tilderadio is a single-station catalogue — one community stream for the whole
tildeverse — so "the bundled station list" is that one station.  The mounts
below are the ones the AzuraCast instance has served for years; the live list
from ``/api/now/`` always wins, and the URLs are additionally probed by the
player's normal failover.
