82-82: Document the outline offset calculationThe line
projectedPosition.xy += screenNormal / (viewport * 0.25 /* 0.5 */) * offset * projectedPosition.w;contains a commented value (0.5) that differs from the actual value (0.25). Consider adding a comment explaining why 0.25 was chosen over 0.5 for better maintainability.

1-108: Architecture Review: Clean UV2 morphing implementationThe implementation elegantly adds UV2 morphing support while maintaining the shader's existing structure and performance characteristics. The changes are minimal, focused, and follow established patterns, making them easy to maintain and extend.

65-67: LGTM: UV2 variable initialization follows established patterns
The initialization of uv2Updated follows the same pattern as UV1 handling and maintains consistency with the codebase.
91-91: Verify UV2 morphing behavior
The usage of uv2Updated for vUV calculation is correct and consistent with UV1 handling. However, let's verify the morphing behavior across the codebase.
✅ Verification successful
UV2 morphing implementation is correctly isolated
The UV2 morphing implementation in mmdOutline.vertex.ts is properly contained and consistent. The search results show that:
- UV2 attribute is only used in mmdOutline shaders (both GLSL and WGSL versions)
- The morphing includes are correctly placed before the UV2 usage
- No other shaders require UV2 morphing support
