How differential loading serves different browser builds

Angular's differential loading creates two builds and uses the `type="module"` and `nomodule` script attributes to automatically serve a lightweight version to modern browsers.

How differential loading identifies browser capabilities

The mechanism relies on the browser's native support for `type="module"` and `nomodule` attributes, not user-agent sniffing, to determine which build to load.
