# Wraps the agent in "Frame Mac View Lab.app" for testing from a terminal or
# an agent session: macOS then asks for Screen Recording and Accessibility
# for this app rather than for the terminal. Signed with an Apple Development
# identity if there is one, so the permissions survive rebuilds.

#                                        readable only by you: the token opens every window and injects input)
#   mac/frame-mac-view/lab.sh serve-only restart it without rebuilding
