"""Guards for the module boundaries introduced by the modularity refactor.

Three things must hold so the split stays invisible to callers:
  * the new leaf modules own their logic and behave correctly,
  * ``browser_cli.client`` still re-exports the names that moved out of it, and
  * ``BrowserCLI`` still exposes the factory/routing helpers (now mixins).
