The Web page designer remembers the last-edited layout for each page

When you open a Web page in Studio's visual designer, it always starts on the Medium layout. If a page's main target is Compact or Wide, you have to click the layout you actually want every time, on every page, in every session.

Studio should remember the last layout (Compact, Medium, or Wide) you edited for each page, so reopening a page — or reloading the project — puts the designer back on the layout you were working with. Each page remembers its own layout independently, so a project can keep some pages on Compact, others on Medium or Wide.

This is personal editor state: it is remembered on your machine and is not written into the project itself.
