Y2K aesthetic typography — early 2000s chrome bubble letters, holographic gradient surfaces, liquid metallic sheen. Nostalgic millennium style with modern premium execution. Tall vertical 9:16 portrait composition. Deep navy-indigo gradient background — rich midnight blue at top fading to deep violet at base, holographic shimmer layer over the gradient. The Y2K chrome bubble text is positioned in the upper-center third, spanning 75% of frame width — aesthetic poster placement. The text is stacked in three lines with clear hierarchy: a smaller top line reads "Y2K AESTHETIC", the bold oversized centerpiece reads "THAT GIRL", and a delicate subtitle line beneath reads "Est. 2000". Electric pink and cyan arcs reflect across the chrome letter surfaces. Soft holographic star confetti scattered throughout the background. The overall mood: Y2K aesthetic bedroom poster, dreamy and vibrant.
