Per Codex audit follow-ups:
* Track in-app navigation depth (forward goto/link increments, popstate
unwinds, clamped at 0) and base the in-page Back on it instead of
history.length. A direct deep link (email/social/article) now sends the
in-page Back to Highlights rather than out of the site.
* Apply the same stale-load guard to the Today/Highlights path that feed views
have, and only scroll-to-top when the load is still current — avoids stale
error/scroll state during quick navigation.
