- Add packages() relation to Shipment model - Update CustomerOrderController to accept packages[] array - Auto-calculate volumetric weight from dimensions (L*W*H/5000) - Redesign order form Step 1 with Multi-Package UI - Add package repeater (add/remove packages) - Real-time summary of total weights - Both real weight and dimensions are required - Dimensions normalized to * format (5*6*9) Phase 3.5.1 — Multi-Package complete"
