A small client-side NeoForge 1.21.1 mod that mirrors the logic of Cosmonautics PR #164 / issue #157. It stops SkyHandler.ensureStarPlasmaTexture() from rebuilding and re-uploading the 64x64 plasma noise texture once per tick whenever the star sky isn't actually visible (custom sky off and not in deep space), while preserving the animated boiling plasma on stars when it is shown.
