| ## Session framework |
| |
| Sessions are components that encapsulate a product’s user experience. The |
| session framework serves as a boundary between the Fuchsia platform and the |
| product-level user interaction. Each Fuchsia product defines a single session |
| instance as the root of the product experience, which may or may not manage |
| additional child components. |
| |
| The `session_manager` platform component starts the session component on boot |
| and offers it a fixed set of capabilities necessary to support the session |
| framework APIs for elements such as window management, input event handling, or |
| accessibility. |
| |
