Example

## Try an example

- Keep the courier, his orange rain shell, his sprint, every camera move and every cut exactly as in the reference video, but replace the server farm with a sunlit gothic stone cloister: the black racks become weathered limestone columns and ribbed vaulted arches, the fluorescent strips become tall arched windows pouring hazy volumetric daylight across a worn flagstone floor, dust suspended mid-air, and the glass door at the end becomes a heavy oak door with an iron ring. Warm sandstone and gold palette, soft contrast, footsteps echoing on stone and pigeons scattering.
