New Engineering Layer tab on the engineer image page. A site uploads Engineering_Install_v<ver>.exe (keeps prereqs) or a .zip of the whole extra_engineering payload. The upload is streamed to disk, checked (MZ header, no unsafe zip paths) and swapped in; the replaced payload is archived (two kept) with a Restore button. Install-EngineeringLayer.ps1 stays repo-owned and now installs the newest Engineering_Install_v*.exe. KB: Part 4 becomes Site Content (enrollment package, Engineering Layer, Blancco site settings, Shop Floor apps) plus a new Adding Shop Floor Apps section for preinstall.json/postppkg.json. WJ examples removed.
