// Pure helpers: Yu-Gi-Oh! set-completion progress and per-set checklists.
// Ownership counts only when collection card.set.id matches the pack and the
// printing slot matches a catalog setNo (ygoPrintingSlotsMatch). Duplicates /
// amount / rarity / firstEdition do not inflate the numerator. An optional
// languageFilter restricts ownership to cards of that language (packs with
// zero matches are omitted).
