ARCHY — the practice that draws both sides

One-shot for an architecture and structural engineering firm. A bone-white plate-helix turns on a seamless loop behind a wordmark kerned to the viewport edges; chapters hand over rather than cut, the same object returns posed three ways, a hairline force diagram draws down a real column head, six works ride a pinned horizontal track, and a drag handle wipes a photographed building into its own section drawing. Pure black, white and one grey. No accent colour anywhere. Free example, live demo included.

The prompt copies to your clipboard — the demo above is what it builds.
