What I fixed:
Removed the warning-calculation N+1 queries. Occupancy warnings now use one floor-plan participant query instead of per-scene character/asset lookups.
Added SceneFloorPlanParticipant_ListByFloorPlan to the existing migration script with SET ANSI_NULLS ON and SET QUOTED_IDENTIFIER ON.
Reapplied the migration locally.
Confirmed FloorPlanBlock_Save, FloorPlan_GetEditor, and the new participant proc have quoted identifiers enabled.
Reduced drag/resize freeze risk by throttling expensive geometry recalculation to animation frames instead of every pointer event.
Added a final geometry refresh on pointer-up/cancel before autosave.
Improved autosave failure visibility by showing the real error in the editor, not just leaving status stuck.
Made Occupancy mode view/staging only:Blocks no longer start drag/resize in Occupancy mode.
Resize handles are hidden.
Structural toolbox is hidden.
Plan canvas expands to use the freed width.
Structure mode restores normal editing.
Verification:
dotnet build PlotLine.slnx passes with 0 warnings and 0 errors.
Non-destructive SQL smoke test of FloorPlanBlock_Save against the Lounge block passed inside a transaction and rolled back.
Confirmed the Lounge block stayed unchanged after the rollback.
Reapplied 081_FloorPlanFloorDescriptionAndOccupancyWarnings.sql successfully.

Manual browser QA still needed for the exact drag/add/reload flow, but the code path and SQL save path are now stabilized.
What changed:
Removed the standalone floor-plan details panel under the page title.
Added current-floor Description and editable Root Location into the Floors toolbox tab.
Added live computed Occupancy Warnings in Occupancy mode.
Preserved the existing AJAX workspace flow, including active floor/toolbox tab/mode/selected occupancy scene through refreshes.
Added floor description support via a new migration:
[081_FloorPlanFloorDescriptionAndOccupancyWarnings.sql](C:/Source/PlotLine/PlotLine/Sql/081_FloorPlanFloorDescriptionAndOccupancyWarnings.sql)
Database changes:
Added nullable FloorPlanFloors.Description.
Updated active stored procedures:FloorPlan_GetEditor
FloorPlanFloor_Get
FloorPlanFloor_ListByPlan
FloorPlanFloor_Save
Warnings are not persisted. No warning tables were added.

Verification:
Applied the new migration locally.
Confirmed FloorPlanFloors.Description exists.
Confirmed scene/occupancy source data exists for The Calendar House.
dotnet build PlotLine.slnx passes with 0 warnings and 0 errors.
Manual QA still needed in the browser: edit floor description/root location, switch Structure/Occupancy mode, step scenes, and confirm warnings/tokens update visually without jumps.
