"""Render smoke tests for the M&E SRS UI surfaces added in this sweep.

Ensures every new/changed page renders (HTTP 200) with realistic data so a
template crash can't slip through. UI is guided by the shared topnav / dashboard
shell (page_header_text + breadcrumb + card + mel_badge).

Do NOT run under a parallel pytest — the test_iilmp DB collides.
