Improvements
- Added a legend in comparison mode showing solid lines for the primary result and dashed lines for the secondary result, making it easier to tell the two diagrams apart.
Bug Fixes
- Fixed an issue introduced in v5.7.1 where the application window could not be moved by dragging the title bar.
- Fixed an issue where the longitudinal reinforcement spacing check showed a broken equation in the report when no reinforcement was present. The report now displays a clean "No Reinforcement Layers" message instead.
