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.

Only one shape visible — the purple and cyan shapes may be hidden behind? At t=0 all overlap center; pink is on top (s3 last in DOM). Overlapping is expected at start; as they orbit they separate. Fine. Sample a mid-frame.
Shapes start overlapped at center (they separate as the timeline runs). Let me sample mid-animation:

Shapes separate, rotate, morph, dots stagger visible. Good. Test pause/resume and restart.
Shapes orbit, scale, and morph; dots stagger clearly. Now test Pause/Resume and Restart:

Resume continued from paused position, animation progressing. Now test Restart.
Resume continued correctly. Now Restart:

Done — `index.html` is complete and verified. **What it contains:** - Dark background, centered composition using the local `gsap.min.js`. - Three rounded shapes (purple square, cyan circle-ish pill, pink square) that orbit outward, scale up, rotate, and morph border-radius, then return to center — the timeline ends exactly where it began, so the loop repeats with no jump (total 4.2s, infinite repeat). - Five dots with two staggered bounce/opacity waves (0s and 2.1s). - Pause/Resume and Restart buttons (a single tween-set timeline, so no accumulating animation instances). **Verified in browser:** - Initial state: shapes overlapped at center, dots dim. - Motion frames at ~0.5–1.6s: shapes separated, scaled, rotated with eased motion; dot stagger clearly visible mid-wave. - Pause: froze at current composition, button switched to "Resume"; Resume continued smoothly from that exact position (confirmed via subsequent motion frames). - Restart: returned to the exact starting composition (single pink square at center, dim dots). Not verified visually: the loop seam at t=4.2s (should be seamless since tweens end at start values, but I didn't capture that exact frame), and behavior under rapid pause/restart clicks.
