Aurora Drift
Soft blurred blobs of color slowly drift across the photo like aurora light — a living, painterly wash.

Runs continuously — adjust the sliders and watch.

Aurora Drift floats three soft, blurred color blobs over the photo and slowly drifts them, for a living painterly wash. Only the transform animates (cheap on the compositor); the blur is applied once and stays static. Tune --ifx-aurora-c1/c2/c3 (the three colors), --ifx-aurora-op (keep it conservative, ~0.25-0.35, or it muddies the photo), --ifx-aurora-dur (drift pace) and --ifx-aurora-blend (color-dodge/screen keep it luminous). The overlay lives on a ::after that bleeds past the frame and is clipped by the card, so its edges stay soft. Identical on touch; the global reduced-motion block stops the drift.
Modern evergreen.
