- Derive As from the provided longitudinal bars instead of taking it as input; drop the redundant As_bars output and update tests. - Draw a fixed schematic 1 in cover and pin the bottom bars to the stirrup's bottom leg so the figure no longer depends on cover or d. - Fixed stirrup stroke with a rounded 3 pt corner radius. - Right-align the figure, constrain its caption to the image width, and shorten the caption to "Beam cross-section". - Document input.yaml fields.
