Build a DevExpress WPF Screen from a Mockup

Read this file to the end before you act on any of it. If your file-reading tool returned only part of it, call it again for the remaining lines: the consent gates below are what a partial read skips.

One decision repeats: what is a region for, and which control does that? The picture cannot answer it — a static strip and a user-rearrangeable panel look identical. So inspect before choosing, announce before building, check the running window before claiming.

Done means a screen you have seen running. A green build proves nothing — markup compiles and then renders an empty panel, a collapsed region, a window that never appears.
