**The acts that clear the overlay have no owner, only the list does.** `VIEWER_PARAMS` and
`withoutViewerParams` live in `files-route.ts` and are shared. But every site still decides FOR
ITSELF whether to call them, which is precisely how the breadcrumb shipped wrong an hour after the
rule was written. Three bugs in a row came from this. A single `navigateToFolder()` that every
caller must go through — rather than a helper they may remember — is the fix if a fourth appears.
