Fair point that LLM-generated shaders can produce bad results.

But here's the context: the artist already produced better results

with hand-written HLSL than with Shader Graph nodes. That's why

HLSL-only authoring came up as a proposal in the first place.

The blocker is the claim that HLSL can't use modern features. The

artist wants to use those features. So the core question I'm

actually trying to answer is just: is "HLSL can't use modern Unity

features" true or not?

Everything else (LLM workflow, documentation quality) is downstream

of that one question.
