Key Points

• GridResource sets layout() to 'Grid' and returns empty form()
• totals() with source_column enables live client-side aggregation
• The post action uses requiresConfirmation() — user must confirm before execution
• After posting, the handler returns a fresh empty grid via toGridJson()
• The Balance total updates in real-time as the user enters amounts
