“AT”是使用 FontVibe AI 创作的优雅手写体文字效果。精致的金色手写体，发丝般的长花饰与回环大写，置于哑光黑或象牙白卡纸上，旁有奢华道具，柔和掠射光。

Create a finished, square, flat-vector stamp logo. Render only the exact initials “AT” as one unified, legible monogram: a large, chunky geometric capital T forms the outer structure, with a clearly recognizable capital A nested centrally inside it. Interlock the forms cleanly while keeping generous white negative-space gaps between strokes and open counters in the A. Place one simple, bold leaf silhouette directly above the T’s top bar, with a clear gap so it does not merge into the letter. Enclose the complete monogram and leaf within one centered, very thick black circular border. Use pure black shapes on a pure white background, crisp hard edges, consistent heavy stroke weight, simple geometry, and strong contrast. Keep every shape bold enough to remain readable at small size and suitable for carving into a wood branding iron. Refined premium-brand restraint comes from the balanced proportions and breathing room, not from ornament or effects. Strictly flat vector artwork: no gradients, metallic finish, embossing, texture, shadows, thin strokes, extra text, or additional decorative details.
