Subtracts the DXF header extents centroid (world_offset) from all coordinates in f64 BEFORE casting to f32. This eliminates the ~0.5 m ULP error that occurs at 4,000,000 m UTM coordinates and caused geometry to disappear on zoom-out. - Scene: adds world_offset field + compute_and_set_world_offset() method - tessellate.rs: threads world_offset through all f64→f32 conversions (legacy_geometry, dimension_geometry, solid_wire_fallback, multileader) - truck_tess.rs: to_local() helper already in place from prior session - mod.rs: tessellate_entity() and entity_aabb() apply world_offset - update.rs: compute_and_set_world_offset() called after doc load - cmd_result.rs / solid3d_cmds.rs: pass correct offset to truck tessellators Co-Authored-By: Claude Sonnet 4.6 <[email protected]>
