+# 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):
