Lookup the localised reader-value description for an artifact. Returns undefined when the artifact is not in the central map so callers can fall through to the next tier of their localisation chain (curated per-language entry → English curated → localised default).
Alias-group resolution: when the requested filename has no direct entry, we consult aliasGroupFor (the single source of truth for filename-variant equivalence) so any new alias filename inherits its group's description automatically without having to update this file in lockstep.
