## Headless smoke test for the AuthPanel login/register flow.
##
## Run with:
##     godot --headless --path . --script res://scripts/smoke_test_auth.gd
##
## Requires the backend to be running (default base URL
## `application/agp/api_base_url` -> http://127.0.0.1:8000).
##
## Tests:
##   1. Register a unique user → 201 + token stored.
##   2. Register the same user again → 409 "Username already registered".
##   3. Register an under-18 user → 400 "Must be 18 or older".
##   4. Login with correct credentials → 200 + token stored.
##   5. Login with wrong password → 401 "Incorrect username or password".
##   6. Login with non-existent user → 401 "Incorrect username or password".
##
## Exits 0 on full pass, 1 on any failure.
