**Chart usage notes:**
- `year` is numeric (negative = BCE, positive = CE) for x-axis.
- `label` is for tooltips or point labels.
- `era` can drive color or grouping.
- Prehistory (stone tools, fire) omitted from this array because of scale; they can be added with `year: -1000000` and `year: -3300000` if using a log or dual-scale timeline.
