Global mutable instance

notificationInstance is a module-level mutable singleton that gets set by setNotificationInstance() and then used by getNotification(). In Next.js/React this can lead to cross-request/user bleed in SSR/hydration scenarios (the module is shared), and also makes notification behavior depend on mount order (calls before AntdAppInit runs will silently use the static API). A safer pattern is to keep notifications entirely context-driven (or pass the instance explicitly) rather than storing it in a global variable.

Comment:
**Global mutable instance**

`notificationInstance` is a module-level mutable singleton that gets set by `setNotificationInstance()` and then used by `getNotification()`. In Next.js/React this can lead to cross-request/user bleed in SSR/hydration scenarios (the module is shared), and also makes notification behavior depend on mount order (calls before `AntdAppInit` runs will silently use the static API). A safer pattern is to keep notifications entirely context-driven (or pass the instance explicitly) rather than storing it in a global variable.

How can I resolve this? If you propose a fix, please make it concise.
