Mainly only useful for Wild West, which doesn't use `channel_ids` (otherwise, the homepage maintainer could just exclude the id from `channel_ids` directly).
The `useDualLayout` junk is super confusing to maintain and no longer extensible.
At the expense of making the "livestream + regular" list no longer seamlessly continuous when expanded (or when there just a handful of livestreams), use the new `subSection` feature to inject the livestream tiles. This is far easier to manage and tweak.
