Pixel counts below will update as the window is resized. Below 200px, we show a thumbnail and link. From 200-399px, we show a reduced interface. 400px and above gets the complete experience.
When the viewport is wide enough, this will display at 702px, which means the page image will be rendered at its native 700px width. Useful for doing pixel-level comparisons with the workspace and Document Viewer.
