# copied into a scratch dir; only that copy is mutated.
#
# In a REAL consuming repo you would not pass --manifest at all — the installed
# @whynot/design package supplies its own ir/manifest.json, and the lock lives at
# ./.whynot-design.lock. Here we point at the repo copy so the demo is hermetic.
