@copilot rebase this pull request on the latest version of the portrait-layout branch (https://github.com/guardian/dotcom-rendering/tree/portrait-layout)

The branch already incorporates the latest portrait-layout tip (b31f2dfb59) via the merge commit b1372f66. A true rebase (to produce a clean linear history) requires a force push, which is not available in my tooling — any attempt is rejected and the local state is reset to match the remote.

The code changes are identical to what a rebase would produce. If you'd like to clean up the history with a force push, you'd need to do that manually:

git checkout aa/portrait-layout-continued
git rebase origin/portrait-layout
git push --force-with-lease
