-- Award reference lists (Parks On The Air, SOTA summits, WWFF, IOTA…).
-- Each row is one valid reference for an award, used to provide award totals,
-- reference names, and (later) per-QSO reference assignment + per-DXCC filtering.
-- Lists are downloaded/updated from each program's published file.
