# Launch the Dreamverse Next.js frontend in dev mode on port 5299
# (the devtools-enabled build the e2e tests target).

# Usage:
#   bash launch_frontend.sh
#   FRONTEND_MODE=dev bash launch_frontend.sh        # plain dev (5299, no devtools)
#   FRONTEND_MODE=single5s bash launch_frontend.sh   # single-5s product mode
#
# The script ``cd``'s into ``web`` and shells out to npm. It runs
# ``npm ci`` only when ``node_modules/`` is missing so repeat
# launches are fast.
