Taxonomy cross-reference

Each row is one of the 98 fine-grained Rozental tags. Columns map the tag to the corresponding category in each existing corpus tagset (RLC, RULEC-GEC, GERA, LoRuGEC) and note L2 applicability. Cell colors carry meaning: yellow for covered, red for not, green for high confidence — the rendering is parsed live from the .xlsx, so it matches the source.
