Riemersma dither produced visible "ink-spill" Hilbert-curve streaks in low-contrast regions like skin. Reverting DITHER_METHOD to Floyd- Steinberg and attacking the original sky-bleeds-into-face problem with a pre-dither Gaussian blur instead: DITHER_METHOD RIEMERSMA → FLOYDSTEINBERG (back to baseline) + new BLUR_SIGMA = 0.6 (pre-dither softening; baseline 0.0) Live tunables are now public so RenderCompareCommand can mirror them. Half-A of app:render-compare is locked to the frozen-baseline set (sat=130 gamma=1.0 sharpen=0.8 blur=0.0 FS) — what shipped at git tag render-baseline-2026-05-14. Half-B always tracks the live pipeline, so each future experiment is automatically the next A/B without touching the comparison command.
