The impossible museum in one continuous shot

Design a [DURATION]-second apparent single-take tour through an imaginary museum about [THEME]. Start on [OBJECT] in an ordinary room. As the camera moves, the room subtly becomes three eras, each with one concrete detail that carries into the next era.

Specify a continuous camera path, lens feel, practical or generated transition points, consistent spatial geometry, light shifts, sound cues and subject actions. Map every five seconds to what appears in frame and where the viewer should look. The museum must tell one clear story through objects rather than wall text. End by returning to the first object with a new meaning.

Provide a generation prompt, per-transition continuity locks, a shot-by-shot fallback for tools that cannot hold a long take, and a review checklist for geometry, object permanence and historical claims. Do not present fictional artefacts as real history.
