User-configurable settings from the SolariLighting component, plus per-frame state. Field order and types must match SolariLightingUniforms in prepare.rs.

struct SolariLightingSettings {

confidence_weight_cap: f32 ,

primary_di_samples: u32 ,

secondary_di_samples: u32 ,

max_bounces: u32 ,

world_cache_max_temporal_samples: f32 ,

world_cache_max_gi_ray_distance: f32 ,

world_cache_cell_updates_soft_target: u32 ,

world_cache_position_base_cell_size: f32 ,

world_cache_position_lod_scale: f32 ,
