# Boot the full leaflet_svelte ↔ stratoflights ↔ predictor test stack.
#
# Processes started (background):
#   - fake_tawhiri (Python http.server, :8001)   — synthesizes prediction responses
#   - stratoflights Django (runserver, :8000)    — API backend, talks to fake_tawhiri
#   - leaflet_svelte Vite dev server (:5173)     — proxies /api to Django
#
# After this, run tests with:
#   npm run test:e2e
#
# Stop everything with:
#   scripts/stop-stack.sh
#
# Requirements (once):
#   - Python deps: pip install --user --break-system-packages Django djangorestframework \
#       djangorestframework-simplejwt drf-spectacular requests django-cors-headers \
#       Pillow python-dotenv channels daphne
#   - `demo` user in Django with password `demo`:
#       DJANGO_ENV=production python3 manage.py createsuperuser (--noinput with env)
