test_settings.py

"""
Test-only Django settings.
Imports base settings, then overrides for isolated tests.

Tests always use PostgreSQL (same as CI and production) so behavior matches
JSONB, case-sensitive ILIKE, connection pooling, and transaction semantics.
SQLite is not used: it can hide bugs that only appear on Postgres.
