# The repo's dev-licence.json is a TEAM licence: it names no machine and no
# install, and says so in its signed body (scope: team). Whoever can clone this
# repo can run dev mode - repo access is the credential, deliberately, because
# an operator has the installed launcher and never the source.
#
# A launcher started FROM this repo (npm run tauri dev) finds the licence by
# itself: it looks beside its own exe and two levels up, which is this folder.
# An INSTALLED launcher looks in its own install folder, so this script puts a
# copy there. Run it once; then open Settings and the Dev section is there.
