This server-only facet uses node-specific functionality to create an HTTP server on the designated port. It allows the ecosystem to server-render a snapshot of its GUI as a single HTML document with inlined CSS and JavaScript. This acts as a bootstrap which fetches and installs the ecosystem as a service worker (offline server) and then hydrates the snapshot.

When the environment is "node-main" (and not "node-module"), it gathers information about other version deployments and can serve them by importing them as modules.

It provides http-to-https redirects, ensures that the "www." subdomain is removed, redirects from canonical URLs, provides version information for the update manager, and redirects certain canonical paths (like "/") to the appropriate versioned and stateful counterpart.
