// 問題バンクのシード生成スクリプト。
// Edge Function jq-generate-problems を Lv1-3 × 易中難 で呼び、DB を満たす。
//
// 使い方:
//   1) .env に VITE_SUPABASE_URL / VITE_SUPABASE_ANON_KEY を設定
//   2) Edge Function をデプロイ済み (supabase functions deploy jq-generate-problems)
//   3) node scripts/seed.mjs [count]
//
// count: 各 level×difficulty あたりの生成数 (既定 8)
