Notes

—The repo uses a shared nested schema across splits.
—The train split is streamed directly from train.zip and uploaded as parquet shards to reduce local disk usage.
—The test split uses the 10-class chart-element mapping defined in the LineEX codebase.
—The train split 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.
