Animate this original artwork as a refined five-second website hero media asset. The exact ornate hotel lobby remains still as chandelier crystals sparkle subtly and warm reflections shift on the polished marble. Preserve all architecture, symmetry, staircases and furniture. 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.
