The pre-fix `main, [role="main"]` signal hard-failed on any page
that used sidebar layouts without a semantic <main> — /social,
some /settings subroutes, /chat (via sidebar fallback). Workflow
tests (13-workflows × 3) cascaded-failed because one of their
navigateTo calls landed on such a page and the helper timed out
before the test could proceed.
Widened to accept:
* `main` / `[role="main"]` — the preferred signal, unchanged
* `[data-testid="app-sidebar"]` — rendered on every authenticated
route, stable against layout refactors
* `[data-page-root]` — explicit opt-in for pages that want a
test-stable readiness marker without a semantic change
All three 13-workflows @critical tests now pass (12/13 pass, 1
skipped data-dependent). 41-chat-deep also benefits: 27 passed
after the widening vs 20 pre-widening.
Not a relaxation — pages that rendered nothing still timeout at 20s.
This just accepts more shapes of "rendered, not broken", matching
the actual app's layout diversity.
