* Position the in-feed Back button to the right of the view title (inline with
it) instead of stacked above; the accent underline moves under the title text.
* Deep-linking a source feed from an article page (/?source=<id>) now seeds the
back history so the Back button appears (returns to Highlights).
* Strip the ?source= param after consuming it (replaceState) so it can't linger
and make the browser back/forward behave oddly.
