				<div class="class-description"><p>Temporal reprojection pass for denoising screen-space effects (SSGI, SSR, etc.).</p>
<p>Both modes share geometrically-weighted 4-tap bilinear history sampling and YCoCg variance clipping.
Surface velocity reprojection is always sampled first. Specular mode then blends in
hit-point parallax history on top of that surface result.
Diffuse mode applies velocity-field divergence to detect surface stretching.</p>
<p>Unlike jitter-based TAA/TAAU, this node does not apply camera sub-pixel jitter — it only
reprojects and accumulates history using motion vectors.</p>
