Rizzo is the UI layer for lonelyplanet.com. Rizzo also serves LP's header and footer, assets and Style Guide.
The main goal of Rizzo is to enable sharing of templates and assets across all LP applications. This helps us to reduce complexity and increase reusability. There is a write-up of the thought process behind Rizzo on the engineering blog.
