Light Overlay

Calls something that is on Kiln's roadmap. Parts of it may already run.

Evidence

Ran on Kiln's test stand (2026-11-04): LightOverlay did not start: java.lang.NoSuchFieldError: Class com.mojang.blaze3d.platform.InputConstants does not have member field 'com.mojang.blaze3d.platform.InputConstants$Key UNKNOWN'.
