• Input Binding: Read rows declaratively with @db.input() — data injected into your handler
• Output Binding: Write rows declaratively with @db.output() and DbOut.set()
• Client Injection: Full imperative control with @db.inject_reader() / @db.inject_writer()
• Multi-DB Support: PostgreSQL, MySQL, SQL Server via SQLAlchemy
