Examples shorter than 4 words (like pronunciation guides
"discutir(dees-koo-teer)") are now rejected by both
isBlankResolvable and buildQuestion. The engine only picks real
multi-word sentences for the quiz prompt.
Every card already has at least one real sentence alongside its
phonetic entries, so no data regeneration is needed — the filter
alone fixes the issue.
