Animate this original artwork as a refined five-second website hero media asset. One golden drop falls from the existing pipette into the open ampoule, creating a delicate surface ripple; liquid highlights shimmer. Preserve all glassware, no new equipment or hands. Preserve original identities, proportions, palette and materials. Locked camera unless explicitly specified. No zoom, cuts, text, UI, new objects or distorted anatomy. Continuous restrained motion; begin and end near the same composition where physically plausible.
