# Render the demo-map screenshots used for visual review into <repo>/Screenshots/demo/.
#
# Usage: Tools/render_screenshots.sh [--verify]
#
# Only the **demo map** is captured: the review staging map exists to hold the
# hero/camera list, not to produce review screenshots. Everything here is what a
# player actually sees when the demo runs.
#
# --verify run Tools/visual_loop.py --verify afterwards and fail if a shot
# does not show the content its expectation describes
#
# The PNGs are committed (see Screenshots/README.md): a reviewer must see exactly
# what the build rendered.
