Notes

The repo uses a shared nested schema across splits.
The test split uses the 10-class chart-element mapping defined in the LineEX codebase.
The selected train subset uses a different chart-element label vocabulary, but the HF feature shape is identical.
lines.line_name is derived from legend structure and may be null when the legend-text association is ambiguous.
