Ship landing
The canonical two-surface pattern: a `containers` entry in .cowork/project.json gives the app its own rail icon, whose `app` renders the sidebar pane and whose `open.file` opens the editor page beside it. Navigation in the pane, content in the page.
Use this shape when you want both a glanceable summary and a full working surface — most real apps end up here. In Cowork: Create → App → Sidebar + workbench app.
Create it
This template is built into Cowork Studio's Create dialog. Open Manage Workspace, pick the matching tab, click its Add button and choose Sidebar + workbench app — name it, and the files land in your workspace ready to edit.
