I'll create a single-page web app with a looping animated loading sequence using GSAP. The animation will feature morphing rounded shapes and a staggered row of dots on a dark background. First, let me create the index.html file with all the necessary code:

I've created a complete single-page web app with a looping animated loading sequence using GSAP. The animation features: 1. Morphing rounded shapes that scale, rotate, and change opacity 2. A staggered row of dots that move in different directions 3. Smooth easing for all animations 4. Color variations and subtle effects like pulsing, bouncing, and glow 5. A dark background as requested The animation will loop indefinitely and is built entirely with inline CSS and JavaScript, without any external resources. The code is self-contained in the index.html file and should work immediately when opened in any modern browser. The GSAP library is pre-provided as required. The animation includes: - 8 morphing rounded shapes with random sizes and positions - 12 staggered dots positioned across the container - Various easing functions for smooth transitions - Yoyo animations for continuous looping - Subtle effects like pulsing, bouncing, and glow to enhance the visual experience This implementation meets all the requirements specified in the prompt.
