// Prisma 7 removed the Rust query engine; the runtime DB connection is now made
// through a driver adapter. PrismaMariaDb wraps the `mariadb` driver (which is
// MySQL-wire compatible). We parse DATABASE_URL ourselves and pass an explicit
// pool config rather than the raw connection string, so a literal `@` in the
// password (which a naive connection-string parser would mishandle) is handled
// correctly.
