Browser Utility Execution Lifecycle
How parameters are computed in local browser memory:
// 1. Read input variables from DOM
const params = getFormValues();
// 2. Compute result locally via deterministic JavaScript algorithms
const output = evaluateUtilityLogic(params);
// 3. Update view and provide immediate copy/export handlers
