Refresh the wiki for NeXroll 2.2.0 Adds the four pages the in-app help button now links to: Dashboard, Preroll Library, Connect, and Backup and Restore. The header help button opens the page matching wherever you are in NeXroll, so every section needed somewhere to point. NeX-Up gains the poster views for Upcoming and Your Trailers, the Generator Studio's shared render, theme and audio settings, and a trailer-storage section covering the reachability question that decides whether downloaded trailers ever play. Troubleshooting gains a System page section covering dependencies, diagnostics and recovery. Home describes 2.2.0 rather than 2.0.4. API Documentation and API had drifted into two rival copies of the same reference; API is the maintained one and API Documentation now redirects to it so existing links keep working. Genre-based preroll mapping, which existed only here, is folded into Configuration rather than lost. One broken anchor in Installation is corrected.
