ロゴキーが次々に現れ、カメラが駆け抜ける3Dキーボードアニメ

Build an animated 3D short of a chunky pastel-blue mechanical keyboard on a soft grey backdrop. Keycaps are rounded and white, with a few dark ones carrying simple app-style logos. The keys pop up one after another with a springy motion while the camera glides low across the rows, swoops in close on single keys, and finally pulls back to reveal keycaps spelling a short title. Add small confetti bursts when keys land and gentle depth of field. Structure the scene so every key, camera move and effect sits on an editable timeline with clear parameters, so an AI agent or a person can retime or restyle it later. Deliver a single project that plays in the browser, about 30 seconds long, with play and scrub controls. Done means the camera path is smooth, the key animation is readable, and the final title is legible.
