User Hub Theme Imports

Theme Imports let User Hub for Fluent load supported hub themes while maintaining independent preview and presentation choices. Theme metadata includes minimum-version compatibility information so a package can describe the plugin version it expects. The documented integration also accounts for FluentCommunity sidebar width and light or dark appearance.

Preview the imported theme in the site's intended presentation before selecting it for members. A theme affects the hub interface and should not be treated as a provider connection or permission change. Public, member, and owner-only section access remains a separate part of the hub configuration.
