No Docker Compose detected. Start the API manually in another terminal, from the repo:

  cd backend
  .\.venv\Scripts\activate   # if you use a venv
  pip install -r requirements.txt   # first time only
  uvicorn app.main:app --reload --host 0.0.0.0 --port 8000

Or use Docker Desktop, then from repo root:  docker compose up --build
