// Regression for the boosted-navigation link-rebinding bug (reported on blog.rose-ash.com):
//   home  --boosted nav-->  a post  --click "edit"-->  lands on /tags (a HOME footer link),
//   not /<slug>/edit. After a boost swap, the swapped-in links carry a STALE binding from
//   the previous page. Run by run-boost-nav-check.sh against an ephemeral host server
//   (serve.sh seeds /compose-demo + the home footer's /tags link).
