不剪輯的抽象動態設計：發光核心化為星雲、符號環，最後又回到核心

提示詞

單一連續的 15 秒無縫動態圖像動畫，無剪接、無鏡頭移動，在帶有細微無限星空粒子的深黑虛空背景上，呈現純粹抽象的流體演化。0–3 秒時，中央有一個小型發光藍白色能量核心柔和地脈動，散發出纖細的光之觸鬚，輕柔地向外擴展。

3–7 秒時，核心變形並爆發，轉化為充滿鮮明電光藍、洋紅與金色調的旋轉宇宙星雲雲團；粒子如液態極光般流動，帶著柔和的發光軌跡與細微的鏡頭光暈，形成有機凝聚而成的精細分形圖案。

7–11 秒時，星雲凝聚並轉化為由發光幾何符號（圓形、六邊形與波形）組成的動態環繞光環，緩慢地圍繞中央明亮光球旋轉；能量弧線以節奏性的脈衝連接彼此，營造出無限宇宙機械的感覺。

11–15 秒時，光環與符號優雅地向內塌縮，粒子平滑消散，重新形成簡潔、優雅的風格化未來感標誌徽章（一個帶有發光核心的俐落交織軌道符號），定格於中央，伴隨最後一次明亮脈衝，微弱的殘留光跡逐漸淡出至黑色之中。

超流暢的流體粒子模擬，形變過程具備高度數學精準度，電影感體積光，柔和光暈與散景效果，鮮明卻優雅的色彩配置，在黑色背景上呈現高對比，以 Bauhaus 為靈感的簡潔構圖結合空靈科幻美學，完美的節奏與無縫轉場，1080p，極簡卻史詩般的感受，除了最後的標誌呈現之外不含文字。

Single continuous 15-second seamless motion graphics animation, no cuts, no camera movement, pure abstract fluid evolution on a deep black void background with subtle infinite starfield particles. Start at 0-3s with a small glowing blue-white energy core pulsing softly at center, emitting delicate light tendrils that gently expand outward.

At 3-7s the core morphs and bursts into swirling cosmic nebulae clouds in vibrant electric blue, magenta, and gold hues, particles flowing like liquid aurora with soft glowing trails and subtle lens flares, forming intricate fractal patterns that organically coalesce.

At 7-11s the nebulae condense and transform into a dynamic orbiting ring of luminous geometric symbols (circles, hexagons, and wave forms) rotating slowly around a central bright orb, with energy arcs connecting them in rhythmic pulses, creating a sense of infinite cosmic machinery.

At 11-15s the ring and symbols elegantly collapse inward with smooth particle dissipation, reforming into a clean, elegant stylized futuristic logo emblem (a sleek interlocking orbit symbol with glowing core), settling centered with a final bright pulse and faint residual light trails fading to black.

Ultra-smooth fluid particle simulation, high mathematical precision in morphing, cinematic volumetric lighting, soft glows and bokeh effects, vibrant yet elegant color palette with high contrast against black, Bauhaus-inspired clean composition mixed with ethereal sci-fi aesthetic, perfect timing and seamless transitions, 1080p, minimalist yet epic feel, no text except the final logo reveal.
