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.

Created `index.html` (self-contained, loading local `gsap.min.js` via a plain script tag; no external assets/CDNs). **What it does** - Dark, centered glass-card composition with 4 rounded geometric shapes (coral/teal/amber/violet) that morph corner-radius, hop, gather/spin/shrink to center, burst into a diamond, then glide home — plus 5 dots doing two staggered ripple waves (y/opacity/scale), a breathing "LOADING" word, and a fill-then-drain progress bar. - A single GSAP master timeline (`repeat:-1`, 4.00s, `sine`/`power2`/`back` easing) coordinates everything. The final segment returns every property to its exact starting value (rotation normalized 360→0 at the seam), so looping has no jump and no new animation instances are ever created. - Controls: Pause/Resume toggle (`tl.pause()` freezes the playhead, `tl.play()` resumes from it; button/state pill/time readout update) and Restart (`tl.restart()` on the same instance). Space / R keyboard shortcuts and live Time + Loop counters included. A `window.__loader` handle is exposed for programmatic sampling. **Verified in the browser** - Initial render: centered composition fully visible, no console errors (only the sandbox iframe warning). - Motion sampling across multiple frames: shapes visibly change scale/position/rotation/border-radius, dots ripple with stagger, progress bar tracks the loop, and the counter rolled into Loop 2+ seamlessly. - Pause: froze at 0.89s with "Paused/Resume" state; Resume: continued from ~0.89s onward (not from 0). - Restart: returned to ~0.07s, Loop 1, with the starting row of shapes restored. **Not verified**: very small/mobile viewport rendering beyond the responsive CSS, and keyboard shortcuts were not exercised (button paths for the same functions were).
