Changed:

[Edit.cshtml (line 1729)](C:/Source/PlotLine/PlotLine/Views/FloorPlans/Edit.cshtml:1729): Ladder To Location filtering now lists placed locations on floors above, sorted by level/floor/name with clean labels like First Floor > East Hallway 1st.
[Edit.cshtml (line 2072)](C:/Source/PlotLine/PlotLine/Views/FloorPlans/Edit.cshtml:2072): Ladder renders inside the From Location using the existing position system.
[CoreServices.cs (line 7966)](C:/Source/PlotLine/PlotLine/Services/CoreServices.cs:7966): server validation now treats Ladder as a vertical upward transition, without stairs reciprocity.
[CoreModels.cs (line 1243)](C:/Source/PlotLine/PlotLine/Models/CoreModels.cs:1243): normalisation accepts Ladders.
[site.css (line 4902)](C:/Source/PlotLine/PlotLine/wwwroot/css/site.css:4902) and minified CSS: added light/dark styling for the new marker types.
