Animated loader · kimi-k2-thinking

The user wants me to:
1. Create a single-page web app in index.html
2. Use gsap.min.js which is already available in the current directory
3. Create a looping animated loading sequence on a dark background
4. Include morphing rounded shapes and a staggered row of dots
5. Use a GSAP timeline with smooth easing
6. No external resources, everything inline, no CDN

First, I need to check what's in the current directory to understand the structure.

Good, gsap.min.js is present in the current directory. Now I'll create index.html with the animated loading sequence using GSAP.

The requirements are:
1. Dark background
2. Looping animated loading sequence
3. Morphing rounded shapes
4. Staggered row of dots
5. GSAP timeline with smooth easing

I'll create:
- A main container with a dark background
- SVG or div elements for morphing shapes
- Dots in a row for the staggered animation
- A GSAP timeline that loops infinitely
- Smooth easing functions (like power2.inOut, elastic, etc.)

Let me create the index.html file with all CSS and JS inline.

Great! I've successfully created the index.html file with a looping animated loading sequence. Let me verify the file was created properly and check its contents to make sure everything is correct.

Perfect! I've successfully created the index.html file with a GSAP-powered looping animated loading sequence. Here's what I included:

1. **Dark background** (#121212) with flexbox centering
2. **Morphing rounded shape**:
   - A 120px shape that morphs between circle, rounded square, and back
   - Uses border-radius and rotation transformations
   - Purple gradient with shadow
   - Scale animations for added depth

3. **Staggered row of dots**:
   - 5 dots with pink/purple gradient
   - Staggered animation using GSAP's stagger property
   - Each dot bounces up and down with 0.1s delay between each
   - Scale animation on hover for extra effect

4. **GSAP timeline features**:
   - `mainTl` as the main timeline with `repeat: -1` for infinite looping
   - Separate timelines for shape morphing and dots
   - Yoyo effect for smooth back-and-forth motion
   - Various easing functions: power2.inOut, back.out, elastic.out
   - Smooth 2-3 second durations for fluid motion

5. **Additional effects**:
   - Pulsing ring that expands and fades
   - Loading text that fades in and out
   - Sparkle particles that emit from the center periodically
   - Entrance animations for all elements

The animation follows this sequence:
- Shape morphs continuously from circle → rounded square → square → circle
- Dots bounce up and down in a staggered wave pattern
- Everything loops infinitely with smooth easing
- All animations are synchronized using GSAP timelines

The file is completely self-contained with inline CSS and JS, loading only the pre-provided gsap.min.js file.
