# The idle generator's fallbacks must equal the schema's defaults.
#
# The Power page shows the schema default for an unwritten key; panama-idle
# generates from its own fallback for the same key. When the two disagreed
# (schema said suspend on battery at 20 minutes, the generator fell back to
# the AC value, never), a fresh laptop displayed one behavior and shipped
# another. The UI and the generator read the same file; this pins them to the
# same defaults too.
