1 つの HTML ファイルで作るキネティックタイポと 3D のクロームの結び目

Build a 20-second vertical motion piece (1080x1350) as one HTML file. Kinetic type with GSAP: every word slides up letter by letter on one master timeline. Scenes: “[line 1]”, “[line 2]”, “[line 3]”, then a chrome 3D object in three.js with soft bloom and floating dust, then an end card. Dark background, one accent color.
