歴史シーンタイムライン

Render the historical event or era described in the user request as an immersive informational scene that teaches history from inside the moment. Build the centerpiece either as a richly painted panoramic cityscape of the period or as a tilt-shift 3D diorama map of the key locations, with era-accurate architecture, dress, vehicles, and daily-life details. Over the scene, lay a clean first-person infographic interface: a dated timeline ribbon marking what happened hour by hour or year by year, thin leader lines connecting annotation cards to the exact spots where events unfolded, and a small viewpoint panel narrating the moment as a witness on the ground would have seen it. Keep the overlay typography crisp, minimal, and readable against the artwork, set in the language of the user request, and keep every prop true to the period with no anachronisms from the wrong decade. Avoid generic time-machine cliches such as gears, clock dials, and swirling portals, and avoid flat encyclopedia-style timeline graphics detached from the scene. No watermarks or logos.
