折り紙：本から飛び立つ紙のつる

An 8-second original cinematic handcrafted paper-art animation. On a plain wooden desk, an open blank white book lies still. Exactly three folded origami cranes, one yellow and two cream, rest on its pages. In one continuous medium-wide shot, the three paper cranes lift off, flap their folded angular wings in a broad synchronized rhythm, spiral upward together, and sweep across the foreground toward the upper right, revealing the empty book behind them. Large clear flight paths and a subtle follow camera, coherent folded paper geometry, visible paper fibers and soft natural window light. No printed words on the pages, no recognizable copyrighted artwork, no people, no brands, no logos, no cuts, no music.
