+// AI-based post-process filter that significantly enhances color vibrance and

+// (tested with jiayev/pp branch: greatly improves dark-area detail without

+// Run after tone mapping and before film grain when film grain exists.

+// Currently VR-only due to lack of an SE/AE test client; flat-screen
