"""Seam 1 page check: load a dashboard page with no backend, push contract envelopes
through window.__pyMsg, and assert on what is visible.

Page under test: set PAGE_CHECK_HTML to a generated dashboard.html. Without it, the
no-AI template is filled with TEST_FILL. Every test runs in light, dark and narrow mode.
The page sees a fake Qt bridge: each slot call lands in window.__calls as [slot, ...args].
PAGE_CHECK_WIRED=1: the page is wired to a bot (SAMPLE_DATA off), so sample-data cases skip.
PAGE_CHECK_REPLAY: a JSON-lines file of envelopes a real bot run produced (bot_runner.py's dry run).
Shared helpers (modes, fill, fake bridge, page opener): tests/page_check_common.py.
