The standalone /infrastructure, /workloads, /storage, and /recovery routes
were deliberately retired with the platform-first navigation (abb6f86ae);
these specs existed to pin those routes' filter, handoff, and scoped-routing
contracts, so there is no platform-first surface for them to assert. The
subjects that do survive the rework are covered elsewhere: workload drawers
and filters by the platform-page and embedded-workloads specs, and refresh
resilience by the workloads stability spec being ported to the Proxmox page.
