-"""微信 Native 扫码支付（trade_type=NATIVE）。
+"""微信扫码支付：小程序码（本机相册可扫，直接弹密码）。
 
-「一瞬间出密码」= 二维码必须是微信返回的 weixin://wxpay/bizpayurl?...
-他人微信摄像头扫屏幕 → 系统直接弹付款，中间没有网页。
+为什么不用 weixin:// 付款码：
+- 那才是「另一台手机摄像头扫 → 瞬间出密码」的官方 Native
+- 但微信禁止「扫一扫 → 相册」识别付款码（保障支付安全）
 
-本机相册扫这种付款码会被微信官方拦截（保障支付安全）——不是商户能关的。
-本机付款请走小程序「本机支付」JSAPI，同样是一瞬间出密码。
-
-相册可扫的 HTTPS 中转页仍保留（wx-native-pay），但不印进主二维码，
-因为那条路必然经过网页授权，做不到和 weixin:// 一样的「无感弹窗」。
+为什么改用小程序码（微信官方文档也写了可用小程序码替代收款码）：
+- 相册可以识别小程序码
+- 扫完直接进小程序支付页 → wx.requestPayment 出密码
+- 用户体感就是：相册一扫，马上出支付，没有乱七八糟的 H5 网页
