// Tenant scope for the console (#709). The topbar switcher picks a tenant and
// every tenant-aware view (Runs, Usage, Changes) adds `tenant=` to its query.
// A tenant-scoped principal is pinned to its own tenant. On a server built
// without the `tenants` feature the list is null and the switcher hides.
