Description:
Add cirrus and alto cloud layers above volumetric clouds using scrolling 2D textures.
Tasks:

Create 2D cloud textures (cirrus, alto types)
Define altitude layers above 4000m
Implement scrolling at different speeds/directions
Layer multiple 2D clouds
Apply atmospheric lighting
Blend with volumetric clouds below
Test appearance and performance
Ensure cheaper than volumetric approach

Acceptance Criteria:

High clouds visible above volumetric layer
Multiple layers add variety
Scrolling creates motion
Performance impact minimal

Related Issues: Depends on #32

Estimated Time: 2-3 days
