flatten_channels_to_staging()

void MayaFlux::Yantra::GpuDispatchCore::flatten_channels_to_staging ( const std::vector< std::vector< double > > &  channels, const DataStructureInfo &  structure_info  )

protected

Flatten planar double channels into m_staging_floats.

Skipped for structured modalities (glm::vec3 etc.) since those are handled per-binding via PASSTHROUGH or integer paths.
