Adds the v0.9 typed configs and a full dataset card, alongside the existing `wmt26-grand.parquet`, which is unchanged.
**Added:** seven typed configs, each with one split named `evaluation` (the name this repository's first card and the grand file's own metadata use):
| config | rows |
|---|---:|
| `baselines` | 10,753,092 |
| `challenge_sets` | 7 |
| `items` | 26,885 |
| `mt_systems` | 55 |
| `pairs` | 363,242 |
| `submissions` | 11,297,384 |
| `systems` | 73 |
`grand` stays a config of its own (it needs `datasets>=4.7.0`), and `pairs` becomes the default config.
**README.md** is replaced by the full card. The first card's points are kept: one row per item in `grand`, nested JSON payloads, a single evaluation split not partitioned into train/test sets, and raw annotation sessions kept outside the table. The card is rendered from the data, so every number in it is counted, not typed.
**Checks run before this upload:**
- validation: 0 failures (row counts, paper Table 2, personal d…
