#   PROMOTE_NOW=1 bash pull_from_dropbox.sh

# Preserves on Pi: config.ini, content/*.mp4 (logo loops), SGVI ad folders, log/, run/
# Updates: Assets/{01..16,Shared}/, content/*.png|jpg, Python, layouts
# Persistent staging: ~/DyzineFrame-Staging (never deleted)
# Rollback snapshot:   ~/DyzineFrame-Rollback (updated on each promote)
