# Nightly TIF backfill for wallco.ai (runs on prod / Kamatera via crontab).
#
# Builds a full-size TIF for every PUBLISHED design that doesn't have one yet,
# so the /designs/hires/:id mural preview + the full-res colorway recolor stay
# populated as new designs publish. pilot-build-tifs.py --all skips existing
# TIFs, so this is cheap on a steady state (only NEW designs get built).
#
# - flock-guarded so two runs never overlap.
# - --min-free-gb 15 disk guard (aborts before a build if disk runs low).
# - logs to logs/tif-cron.log (rotated when > 5 MB; logs/ is rsync-excluded so
#   the deploy never clobbers it).
#
# Install (idempotent) on prod:
#   ( crontab -l 2>/dev/null | grep -v 'cron-build-tifs.sh'; \
#     echo '30 3 * * * /root/public-projects/wallco-ai/scripts/cron-build-tifs.sh' ) | crontab -
