Lightweight Skyscrapers: Tapering Proportions and Intricate Facades

Design a supertall building emphasizing visual lightness through tapered proportions, refined curtain wall systems, slender structural expression, and minimal roof articulation inspired by Renzo Piano. A tower narrowing continuously toward the top with no crown or cap, extremely fine mullion profiles, the top edge left open and unresolved against the sky, pale reflective glazing, clear bright daylight, low viewpoint emphasising the taper, 24mm lens, ultra photorealistic, 8K
