# What it removes:
#   /* NEXT-EP-POPUP-BEGIN ... */ ... /* NEXT-EP-POPUP-END */

# Defaults to dev. Pass --prod to remove from prod's index.html instead.
# Idempotent: safe to re-run.
#
# After local edit, redeploy to nullstone via the same nsenter cp trick used
# for sub-label-shim revert (see comment at end).
