An **architecturally dominant, profoundly melancholic 5-second sequence** focusing on a **grand, spiraling staircase** in the center of a vast, abandoned office building lobby. The staircase is broken, overgrown with dust and decay, leading upwards into **absolute darkness** and downwards into a similar void. **Lighting:** The only light is the **electric violet neon outline**, which is seen **slowly and tirelessly ascending/descending the endless steps**. Its light dimly illuminates the crumbling marble and rusted railings. **Movement:** The neon entity performs an **unending, monotonous, repetitive climbing motion**, its form slightly wavering with each step on the broken stairs. **Camera Work:** A **slow, continuous, upward-spiral crane shot** that follows the entity, emphasizing the **infinite, futile nature of its journey** and the vast, empty space around it. **Visual Effects:** The violet neon light leaves a **faint, shimmering, but quickly fading afterimage** on the steps, suggesting countless past ascents. **Mood:** **Sisyphean struggle, eternal futility, and architectural despair.**
