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.

Evaluating browser tool limits and planning timeline verification using motion, clicks, and screenshots instead of JS eval.
Initial render looks good — now verifying the loop, stagger, and controls.

Done. `index.html` is saved alongside `gsap.min.js` (loaded via plain local `<script src="gsap.min.js">`, no CDNs/network). What was built: a dark centered loader with 3 gradient rounded shapes (scale/position/corner-radius/rotation morphs) plus 5 staggered bouncing/fading dots, driven by a single GSAP timeline (4.8s, `repeat:-1`, `sine.inOut`) whose end state equals its start state, with rotation normalized each loop so no jump or instance buildup. Pause/Resume (toggles `tl.pause()/play()`) and Restart (`tl.restart()`) controls included. What I actually checked in the browser: - Initial screenshot: composition centered, visible, no console errors (only sandbox warning). - Motion frames sampled across the loop (t≈0.3s through 4.2s + wraparound): shapes visibly changed scale/position/corner-radius each phase, dots showed diagonal staggered wave in size/opacity/height, transitions smooth, loop wrapped without a jump. - Clicked Pause: froze at 2.21s, button flipped to Resume, status showed paused time. - Clicked Resume: continued from ~2.2s → 2.4s (not from zero). - Clicked Restart: returned to t≈0.1s starting composition and kept playing. Unverified: exact pixel values of intermediate transforms (no JS-eval probe available — verified visually instead); long-run stability over many loops beyond the observed ~2 loop wraps.
