  - Trajectories now hide behind real-world objects (walls, furniture) using LiDAR mesh as     
  invisible occluder                                                                           
  - Accurate surface normals on curved surfaces (e.g. cylindrical objects) for precise impact
  angle calculation

  - Fixed tail direction detection: axes now correctly point toward the area of origin         
  - Automatic drop diameter estimation from perspective-corrected minor axis measurement — no  
  manual input needed                                                                          
  - Angle confidence indicator in live overlay (checkmark / warning)                           
  - Ghost lines: classic 2D convergence lines projected on the surface
                                                                                               
  Better Interaction                                                                           
  - Professional crosshair design with corner brackets and center dot                          
  - Tap on a trace to select it, then remove with a dedicated button                           
  - Undo last axis button for quick corrections                                                
  - Show/Hide axes toggle — see only trajectories and convergence by default                   
  - Axis label shows impact angle and measured drop diameter
