AlexanderNyr/auralite-shaders ? reverse-engineered prompt

Build me a Minecraft shader pack that feels modern and realistic, but still stays lightweight and runs well in Iris and Sodium, with support for OptiFine and Oculus too.

I want soft HDR bloom, volumetric godrays, 3D clouds, SSAO, SSR, TAA, and optional FXAA or SMAA, but nothing too flashy like heavy motion blur or overdone bloom. It should support LabPBR materials, look good in both bright daylight and at night, and keep performance smooth with sensible quality presets.

Please make it work for Minecraft 1.16.5 through the newer versions listed in the project, and keep the shader pipeline clean and compatible with modern GLSL. If you need to check current Iris or Minecraft shader docs online, do that. Also make sure the pack has sensible default settings, good shadows, and a polished final look without tanking FPS.
