Unified Realism v0.3 — Atmosphere Rebuild

This version rebuilds the v0.2 finishing layer and adds a dedicated Unified Realism
configuration screen. Main changes:
- configurable cinematic lighting and highlight preservation
- lifted shadow detail without flattening contrast
- weather-aware exposure and rain darkening
- controllable vegetation sway with rain damping
- slower, more natural water motion and adjustable choppiness
- denser and better-defined default volumetric clouds
- improved rain visibility, wet surfaces and splash disturbance
- Portuguese and English option labels

Installation: place the ZIP directly inside .minecraft/shaderpacks and select it in Iris.
Build: 0.3 experimental


Unified Realism v0.3.1 - Dynamic Light Occlusion
------------------------------------------------
- Preserves the v0.3 nighttime lighting balance.
- Adds original screen-space contact occlusion for artificial block lighting.
- Moving players, mobs, and foreground geometry can darken nearby illuminated surfaces.
