Tenant Subdomains in TanStack Start With Router Rewrites
We moved every BugDump portal from bugdump.com/p/acme-store to acme-store.bugdump.com without moving a route file: TanStack Router rewrites the URL on the way in and on the way out. An output rewrite that edits its URL sends links to the wrong host, navigate() can't cross origins, and a wildcard Workers route runs in front of every Custom Domain in the zone.
