+/**
+ * seed-tqk.ts — Push Teachings of Queen Kuntī JSON data into MongoDB.
+ *
+ * Uses the native MongoDB driver (same pattern as seed-tlk.ts) to avoid
+ * Prisma replica-set write requirements.
+ *
+ * TQK is a prose book with no volume structure.
+ * We use volume=0 as the sentinel for "no volumes".
+ *
+ * Collections written:
+ *   - book_meta   → one doc { book: "tqk", data: <intro.json> }
+ *   - prose_chapters → intro segments + 26 chapters
+ *
+ * Usage:
+ *   npx tsx scripts/seed-tqk.ts
