- accept wildcard proxy host domains like *.example.com with validation and normalization - make exact hosts win over overlapping wildcards in generated routes and TLS policies - add unit coverage for host-pattern priority and wildcard domain handling - add a single test:all entry point and clean up lint/typecheck issues so the suite runs cleanly - run mobile layout Playwright checks under both chromium and mobile-iphone
