Initial public release.

- Lightweight forward-rendering shader designed for low-end PCs
- Built and tested primarily for Minecraft 1.21.1
- Focused on underwater and ocean-heavy gameplay
- Custom underwater atmosphere with distance-based fog and color absorption
- Stronger exterior water haze while preserving a translucent appearance
- Clean water surface with reduced vanilla texture visibility
- Smooth underside water surface with approximately 30% opacity
- Lightweight procedural water movement and subtle reflections
- Animated kelp, seagrass, grass and leaves
- Abyss-specific visual adjustments for Hadal Veil
- Biome fog colors are preserved instead of applying one global blue tint
- No shadow maps by default due to their high performance cost on low-end GPUs
- No bloom, SSR, SSAO, volumetric lighting, ray tracing or other heavy effects
- No deferred/composite rendering pipeline
- No additional fullscreen passes
- Simple configuration menu for visual intensity, water, underwater atmosphere and vegetation
