Simplified Temporal Anti-Aliasing: sub-pixel camera jitter (Halton(2,3) sequence) combined
with an exponential history blend, no motion vectors/reprojection. Smooths edges in
static/slow scenes; will visibly smear/ghost under fast camera movement -- an accepted
trade-off for a smaller engine (see docs/research/aaa-engine-techniques.md). WebGL2 and
WebGPU only -- WebGL1 has no sampleable HDR history target to blend against.
