+//! Phase 21 (Track M.3) — Prisma migration adapter (JS / TS).
+//!
+//! Prisma migrations are SQL files generated by `prisma migrate dev`
+//! plus a TS / JS seed script that calls `prisma.$executeRaw`.  Fires
+//! when the surrounding source imports `@prisma/client` and the
+//! function body invokes one of the raw-execution callees.
