Feathering support and Rive Renderer on Android

Submission checklist

• I have confirmed the issue is present in the latest version of rive-android
• I have searched the documentation and forums and could not find an answer
• I have searched existing issues and this is not a duplicate

Description

I have a question regarding the Feathering feature's compatibility on Android runtimes.

Based on my tests and your documentation, I’ve observed the following:

API 31+ (Android 12): Feathering works perfectly with Hardware acceleration enabled.

API 30 (Android 11): Feathering does not render, even when Graphics acceleration is set to Hardware and hw.gpu.mode is set to host.

My questions are:

Is API 31 the official minimum requirement for the Feathering feature, or should it technically work on API 30 with the Rive Renderer?

If it is supported on API 30, is there a specific way to force the Rive Renderer to prevent it from falling back to Canvas?

Additional context

No response

No source file, test, reproduction code, or entry point is named. Start by reproducing the Feathering behavior with rive-android 11.6.0 on the Pixel 4 Android 11 emulator, then compare it with API 31 and inspect the documented renderer configuration. Done means establishing whether API 30 is supported and documenting the expected renderer behavior or required configuration.
