This dataset is the larger training corpus used for the real Maskara
Transformers token-classification model.
It contains 75,000 examples:
- `train.jsonl`: 67,500 examples
- `validation.jsonl`: 3,750 examples
- `test.jsonl`: 3,750 examples

messages, identity prompts, finance prompts, code/log snippets, JSON snippets,
calendar messages, map/travel prompts, and hard negatives.
