 A whole class that only exists for some versions (such as `MatrixStackMixin`, which only makes sense before 1.21.6's GUI rewrite) can keep an empty class body on the other versions. Before splitting a class like that, look for a hook that works on every version: nametags used to hook label rendering, which 1.21.9 changed, and now replace the name while the render state is built (`LivingEntityRendererMixin`), with no version condition at all. An empty mixin changes nothing, and it keeps the mixin configs the same for every version, since JSON can't hold version comments.
 
-Inactive code sits inside a `/* … */` comment, so it can't contain `/* … */` comments itself: use `//` comments in code that's only active for some versions. For the same reason, don't nest multi-line version blocks; use `//?} else if <condition> {` for more than two version ranges, as in `PlayerEntityRendererMixin` and `SaturnRenderState`.
+Inactive code sits inside a `/* … */` comment, so it can't contain `/* … */` comments itself: use `//` comments in code that's only active for some versions. Version blocks can nest (Stonecutter writes an inactive block inside another as `/^ … ^/`, as in `GlassRenderer`), but for more than two ranges of the same thing, prefer `//?} else if <condition> {`, as in `PlayerEntityRendererMixin` and `SaturnRenderState`.
 
 - `./gradlew "Set active project to <mc>"` (or the Stonecutter IntelliJ plugin) rewrites `src/` so that version's code is the uncommented one, for editing it in the IDE.
 - `./gradlew "Reset active project"` switches back to 1.21.11. **Run it before committing**, so `src/` is always committed with 1.21.11 active.
