Prompt for this run
Build a looping loading animation using the provided GSAP library. Use HTML, CSS, and JavaScript as needed. Write it to `index.html` in the current working directory using your file tools. Inline your own CSS and JavaScript. Do not use external assets, CDNs, or network requests. Use the provided `gsap.min.js` (global `gsap`) through a plain local script tag; the runner will inline it into the final artifact. Required behavior: - On a dark background, show a group of rounded geometric shapes that smoothly change scale, position, and corner radius, plus a row of five dots with staggered motion or opacity. - Coordinate both elements using a GSAP timeline with smooth easing. The full sequence lasts 3 to 6 seconds and repeats without an abrupt jump or a growing number of animation instances. - Provide Pause/Resume and Restart controls. Pause freezes the current timeline position; Resume continues from it; Restart returns to the beginning. - Center the composition and keep it visible at the supplied viewport. Use HTML/CSS or inline SVG; no external assets or paid GSAP plugins are available. - Choose the palette and detailed choreography freely. No backend loading operation is required. Verify: Sample the timeline at several moments to inspect shape changes, staggered dot motion, and smooth transitions. Pause and resume to check that animation continues from the paused state, then use Restart and check the starting composition.

thinking
I need to build a looping loading animation using GSAP. Let me break down the requirements: 1. Dark background 2. Group of rounded geometric shapes that smoothly change scale, position, and corner radius 3. Row of five dots with staggered motion or opacity 4. GSAP timeline with smooth easing, lasting 3-6 seconds, repeating without abrupt jumps 5. Pause/Resume and Restart controls 6. Center the composition and keep it visible 7. Use HTML/CSS or inline SVG, no external assets or paid plugins 8. Use the provided gsap.min.js Let me first check what's in the current directory to see the gsap.min.js file.

thinking
Good, I can see gsap.min.js is present. Now let me create the index.html file with the loading animation. I'll need to: 1. Create a dark background 2. Add rounded geometric shapes (circles, rounded squares, etc.) 3. Add a row of 5 dots with staggered animation 4. Use GSAP timeline to coordinate everything 5. Add Pause/Resume and Restart controls 6. Make it loop smoothly Let me write the complete HTML file with inline CSS and JS.

Now let me open the file in the browser to inspect the animation and verify it works correctly.
Now let me open the file in the browser to inspect the animation:
{"action":"reload"}Frame 1, +0ms

{"console":["warning: An iframe which has both allow-scripts and allow-same-origin for its sandbox attribute can escape its sandboxing.","log: Timeline state:","log: Current time: 0.10 s","log: Total duration: 3.50 s","log: Progress: 2.9 %","log: Playing: true","error: tl.cycles is not a function"],"dom":"LOADING\nPause\nResume\nRestart","images":"attached"}
thinking
The animation is working! I can see: 1. A dark background with a gradient 2. A "LOADING" text with a progress line 3. Four rounded geometric shapes in different colors (purple, pink, cyan, orange, green) 4. Five dots below the shapes 5. Control buttons (Pause, Resume, Restart) However, there's an error: `tl.cycles is not a function`. This is because I used `tl.repeat(-1)` which doesn't exist in GSAP. I need to fix this by using the correct API. Let me also check if the pause/resume functionality works correctly. The animation seems to be playing, but I should verify the controls work properly. Let me fix the timeline repetition issue and ensure the pause/resume functionality works correctly.
The animation is working visually, but there's an error: `tl.cycles is not a function`. This is because I used `tl.repeat(-1)` which doesn't exist in GSAP. I need to fix this by using the correct API.
