# The default implementation in the Mobility gem requires fallbacks to be defined when booting the application.
# This patch allows to dynamically reconfigure translations fallbacks, by setting Mobility.store_based_fallbacks attribute.
# The implementation is based on the default fallbacks plugin, with some changes around fetching the list of fallbacks to be used.
