Five tests:
- /shorts/{id} renders the vertical feed with data-id matching the
target short and includes the scrollIntoView bootstrap.
- /shorts/{id} 404s when the id resolves to a non-short video.
- Home page shows .home-shorts-shelf when at least one short exists,
with a link to /shorts/{id} for every shelf card.
- Home page omits the shelf entirely when no shorts exist.
- An unknown URL returns 404 with the branded view, not the bare
framework stacktrace.
