What Changed
Added scene-owned occupancy data:Scenes.FloorPlanID
Scenes.InitialFloorPlanFloorID
new SceneFloorPlanOccupancy table
Added Occupancy section to the Scene Inspector with AJAX save/refresh.
Added Floor Plan editor Structure / Occupancy mode.
Occupancy mode shows linked scenes, previous/next scene controls, and character/asset tokens inside assigned locations.
Character tokens use image thumbnail, then initials fallback. Asset tokens do the same, smaller.
No Features, no new floor-plan architecture, no transition changes.

Migration applied locally.

DB checks confirm 14 linked scenes and 45 occupancy rows.
Manual browser click-through of the authenticated UI still needs a human pass for the AJAX controls and visual token placement.

Changed:
[Edit.cshtml (line 29)](C:/Source/PlotLine/PlotLine/Views/FloorPlans/Edit.cshtml:29): added Sliding Door, French Door, and Ladder marker mappings/SVGs.
[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.
No database changes. No new tables. No Features, architecture, AJAX, or secret/hidden room logic changes.
