Read the frame behind.

A PassNode can publish several named attachments in one render. This route follows beauty, view-normal, and motion-velocity data across the current/previous frame boundary.

The beauty attachment blends the current and previous PassNode frames.

PassNode swaps every requested named texture at the frame boundary; the MRT dictionary remains one scene pass.

ownership-

PassNode owns the color/depth target and named attachment textures; RenderPipeline owns the preview output.

Derived from the official WebGPU postprocessing manual, current MRTNode, PassNode, VelocityNode, and the motion-blur example. Use ?forceWebGL=1 to inspect the explicit direct WebGL2 fallback.
