I adopted B in the card and sped the drift up myself with a slider. The amber water still feels like one flat tone. Give it a slow warmth — light moving through the water — without changing the ink at all, and show me the ink is untouched.

Evaluating image comparison process
I'm looking into how to automatically compare images and patch differences. I need to test a subset of ink with an exact additional mask, using the allowedRegion and focusing on square areas. It would be interesting to compare stages after explicitly selecting with an allowedRegion of [0,0,1,1]. I'm wondering if I can create a diagnostic variant that subtracts the original masked images from an expected black stage using the compare stage as a baseline.

Added slow honey highlights and copper shadows through the clear water. The live view now has soft, uneven illumination around the indigo bloom.
Ink preservation checks:
- Your 0.06t speed and B’s threads are unchanged.
- The original rendering stage matched exactly at 0, 8, 20, and 40 seconds: maximum difference 0.
- The final lighting explicitly keeps the original color wherever any ink is present—including faint edges. The final-image difference maps above show changes in the water, with the ink region black.
