选择一个问题，比较 A 与 B。这里的实验不会改变主计算器中的方案。Choose a question and compare A with B. These experiments do not change your plan in the main calculator.
每个按钮都是独立的预设 A／B 案例；切换实验会重新载入参数，不叠加修改。所有数值都是教学假设，不是经济预测。Each button loads an independent, preset A/B pair. Switching experiments resets the inputs; changes never stack. All values are teaching assumptions, not forecasts.
模型沿用计算器的年度年末投入与支取规则。工资和投入同步增长；未模拟工作期间生活费、税费、市场波动和账户缴费限额。养老金与企业年金金额均为示例，充足率不是成功概率。The model uses annual year-end deposits and withdrawals. Pay and deposits grow together; working-life expenses, taxes, fees, market volatility and account limits are not modeled. Pension and employer-annuity amounts are illustrative; funding coverage is not a success probability.
