### Supporting information

_No response_

Start by locating the FancyZones entry points that handle monitor changes and docking-state detection; the issue does not name specific files or tests. Define how a desktop setup is identified and verify that FancyZones automatically enables for one docking station and disables for another without affecting other setups.
