# Reusable: replace a Shopify product's image(s) with a local hi-res file.
# GATED PROD WRITE — default = DRY RUN. Destructive (deletes images) only with CONFIRM=1.
#
# Usage:
#   PID=<product_id> IMG=<file> ALT="<alt text>" DEL="id1 id2 ..." \
#     [CONFIRM=1] bash refresh-product-image.sh
#
# Adds IMG (base64 attachment, position 1, given ALT), then deletes each id in DEL.
# Idempotent on add: skips if an image with IMG's basename is already attached.
