How to Light a Controlled Chaos Shot (Without Losing Your Mind or Your Props)

I had a client last year who wanted a book cover with tea pouring mid-air into a tilted cup, everything suspended, nothing touching the table. The concept sketch took me twenty minutes. The photography reference hunt took three weeks. The problem was never Photoshop. The problem was that I had no solid framework for how light should actually behave on flying liquid, and every reference image I found was either lit wrong for the mood or technically flawed in ways I couldn’t immediately name.
