"""The mobile-layout bundle (goal 41 T12): the server-side invariants
of the mobile containment contract (docs/spry-conversion.md), plus —
when chromium is present — the full browser audit (test/mobile_audit)
that renders every route at 360/768/1280 and fails on any horizontal
overflow or dialog-fit failure.

CI without chromium: the browser part skips gracefully (print + pass
a SKIP marker, never a FAIL) unless T12MOBILE_BROWSER=1 demands it."""
