# Frame spec for the ssot-check demo GIF.
# Rendered by scripts/render_demo.py (canonical path: demo.tape via vhs).
#
# Output shown is REAL: captured from `python3 ssot_check.py check` run against a
# tiny two-file demo (pricing.md canonical, landing.md a copy) built in a temp
# dir. The demo files are not committed — the arc is: in sync (exit 0), edit the
# copy, re-run showing DRIFTED with file:line (exit 1).
