Payload's admin panel ships its own root layout rendering html/body.
Next allows multiple root layouts only when no app/layout.tsx exists, so
the site's routes move into their own group. Route groups are invisible
to routing: every public URL is unchanged, verified against the build's
route table.
The metadata file conventions deliberately stay at the app/ root. Moving
them into the group renamed /icon.png to /icon-4usi79.png (likewise
apple-icon and opengraph-image) and dropped /robots.txt altogether,
which would have broken the /icon.png cache-control rule, the
outputFileTracingIncludes entry for the share card, and robots.txt.
darkThemeSafety reads app/globals.css off disk rather than importing it,
so it needed its own path fix — a grep for import specifiers misses it,
and it fails as an unrunnable suite rather than a failed assertion.

The endpoint and its exposure control ship together on purpose. The
moment /api/flags exists, app/api/[...path] forwards it — and the
response names every unreleased feature the codebase knows about, along
with whether it is on. Publishing that is the opposite of shipping dark.
Denied on an exact first-segment match, not a prefix, so /api/flagship
does not go down with /api/flags. Next reads the endpoint server-side
over the Docker network, which never transits the public proxy.
jest.setup.js now guards its browser globals. It runs for every suite,
including the one that declares @jest-environment node to exercise the
route handler — NextRequest needs Fetch API globals jsdom lacks, and
there is no window there to define matchMedia on.
