# OmniVoice Studio — universal launcher.
#
# Works on macOS, Linux, and WSL. Starts the FastAPI backend, waits for it
# to become healthy, then opens the web UI in the default browser.
#
# Usage:
#   ./run.sh            # normal launch
#   ./run.sh --no-open  # skip auto-opening browser
# Press Ctrl+C to shut down.
