"""
Smoke tests for base.html — AC 2, 3, 5, 6 (Story 2.1).

Tests that:
- GET / returns 200 with full HTML (not plain text)
- All 8 nav sections are linked in the response
- active_page='dashboard' marks the dashboard link with aria-current="page"
- 404 renders an HTML template (not plain "Not Found" text)
- All 4 flash categories render correctly
