LEDMatrix/test/test_web_smoke.py

"""
Web-UI smoke tests: every page, partial, and critical static asset must render.

These boot the pages blueprint with the same dual registration app.py uses
(un-prefixed primary + /v3 legacy alias) and assert each surface returns 200
with its load-bearing markers present. They exist to catch, in CI, the class
of regression that only shows up when a real request renders a real template:
a broken partial, a missing tab wiring, a renamed element id that JS depends
on, or a static asset that stopped being served.
