Detailed Description

Optional rendering metadata that can be embedded in image files (e.g., PNG tEXt chunks). When present, it records the scene and camera setup used to produce the image, enabling exact ray reconstruction for debugging with nirt.

All floating-point values are stored as full-precision doubles so they can be serialised with std::numeric_limits<double>::max_digits10 significant digits and read back without loss.
