A prompt to start from

Use Tesseract. Create an eight-second silent Tesseract mask-expansion study. Reveal moving water footage through a fixed 500 px circular guide at right of a Cloud canvas. Grow the actual path-mask expansion from 0 to 105 px over 3.4 seconds, beginning at 0.8 seconds; never scale or rewrite the guide geometry. At left use Exposure[-30] “Make / room.” and two small Denim lines “One guide. / More room.” Keep the center and media fixed so the expanded visible area is unmistakable. Demonstrate positive growth only; negative shrink is unsupported in the installed renderer.

Tesseract plugins and runtime downloads are coming soon.
