Cine Prime components and templates

A scroll-driven cinema-prime product story that carries the Series A 40mm from an oversized technical hero through a live object study, cost breakdown, exploded construction, optical trace, three-lens family, and order chapter. One owner-requested optics revision sits over the supplied export: the barrel stops reading as see-through, the front ring is bevelled and engraved, the coated glass mirrors its own studio and shows its rear surface through the front, dust and fibres settle on it, the traced bundles arrive as gradient light rather than hairlines, and the page opens on the ten elements scattered in full light and seats them into the finished lens.
