Two original-preserving native plume repairs

Sulfur Springs v4 adds a separate native1050×1498 candidate correcting two flat pink plume cores. Local fills constrained by unchanged original boundary pixels retain coherent gray volume and the thermal-lit transition. Exactly1,565 RGBA pixels change within1,566 selected pixels;all outside-mask pixels and rows499 onward stay exact. Pools,sulfur drips,rocks,trees,ground shadows and unselected detail remain original. Direct clones v1/v2 and median-calibrated v3 remain rejected;upper-only v4 is superseded and retained exactly in the two-plume v5. Complete native light/dark and both detail inspections accept the bounded repair. Independent PNG decoding and a different sparse boundary solver agree within one8-bit unit in one masked channel;outside-mask identity is exact. Small unselected rock-rim/boundary traces still need separate review.
