"""Official MSigDB Hallmark (h.all) collection brief descriptions — all 50 gene sets.

Source: MSigDB Hallmark collection (Liberzon et al. 2015, Cell Systems), brief descriptions

This module exists so the asset build (`scripts/build_embeddings.py`) is fully offline and
reproducible without R/msigdbr. `scripts/build_descriptions.R` documents the msigdbr regeneration path.
