# Migrates mood entries from the old sandboxed container to the new
# non-sandboxed Application Support location.
#
# Run this once after upgrading to mood v1.2 or later. Safe to re-run —
# won't overwrite if the new location already has entries.
#
# Usage:
#   curl -fsSL https://raw.githubusercontent.com/madhupprasad/mood/main/scripts/migrate_data.sh | bash
# or:
#   bash migrate_data.sh
