# Unified Dropbox pull — EtherGold fixture + DyzineFrame deploy (one rclone session per tree).
#
# Run from ~/EtherGold/sync (preferred):
#   bash pull_all_from_dropbox.sh
#   DRY_RUN=1 bash pull_all_from_dropbox.sh
#
# Skip parts:
#   SKIP_ETHERGOLD=1 bash pull_all_from_dropbox.sh
#   SKIP_DYZINEFRAME=1 bash pull_all_from_dropbox.sh
#
# DyzineFrame: stage only by default (promote 03:00 Atlantic or next boot / Update Now).
#   PROMOTE_DYZINEFRAME=1  — promote staging to live after pull
#   PROMOTE_RESTART=1      — restart supervisor after promote (default 0; restart locally)
#   PROMOTE_NOW=1          — alias for PROMOTE_DYZINEFRAME=1 (bench escape hatch)
#
# Bench profile (disable prod, autostart, etc.):
#   APPLY_BENCH_PROFILE=1 bash pull_all_from_dropbox.sh
#   — or use pull_and_apply_bench.sh
#
# Aliases: pull_from_dropbox.sh (EtherGold/sync and DyzineFrame/sync)
