Build the canonical Kastanozem fixture

Synthetic continental-semiarid Kastanozem on loess-like substrate: mollic surface (chroma 3, value 3) – dark enough for mollic but not dark enough for Chernozem (chroma 3 > 2 in the upper 20 cm); secondary carbonates accumulating in the Bk. By construction:

• mollic: PASSES.

• kastanozem: PASSES.

• chernozem: FAILS.

• phaeozem: PASSES too (WRB 2022 Phaeozems allow carbonates); the key reaches the Kastanozems first.
