Guides you through building Fusion portal shells, the host applications that load and orchestrate multiple Fusion apps inside shared chrome like headers and context selectors. Covers scaffolding with the Fusion Framework CLI, wiring up portal-level modules (analytics, telemetry, navigation), configuring the app loader and routing, and deploying with `ffc portal` commands. The main distinction it enforces is portal versus app concerns: you configure `FrameworkConfigurator` at the portal level, not `AppModuleInitiator`. Useful when you're standing up a new portal or adding features like bookmarks and context switching. The `Apploader` component it mentions is marked experimental, so expect some friction embedding complex apps.
