请读取源码和 CSV 包，解压到同一文件夹，运行现有 render_existing.py 重画这份演示。不要重新生成演示数据。换我的数据前先核对列名、单位、归一化基准和测试条件。连续曲线无点实线，数据图四边框，不静默覆盖旧结果。只回复结果位置和必要的下一步。

Read the source and CSV components, extract both into the same folder and use render_existing.py to redraw the existing teaching inputs. Do not regenerate the demonstration data. Before substituting my data, check columns, units, normalisation and test conditions. Solid unmarked continuous traces; four data-axis borders; never silently overwrite results.
