Animate this original artwork as a refined five-second website hero media asset. Soft sunlight and shadows drift subtly along the exact monumental concrete facade. Small plants move in a breeze. Preserve every wall edge and opening, rigid geometry. 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.
