/**
* DIRECT CALCULATION WITH STDDEV INTEGRATION
* ==========================================
* Replace the d-calc button handler in roll_calculator.html with this code
*
* This includes:
* 1. Diameter calculation with ±2σ ranges
* 2. Weight calculation with ±2σ ranges
* 3. Forklift check with worst-case weight
* 4. Load Optimizer integration with nominal values
*/
