Animated loader · claude-haiku-5.5

I should check the directory first to work efficiently.

I'm planning the HTML structure with a stage containing three morphing shapes animated via GSAP timeline—adjusting border-radius, scale, and position with staggered dots, plus Pause/Resume/Restart controls, looping seamlessly over about 4.8 seconds.

Defining four keyframe states for each shape's position, scale, and radius, with the final state looping back to match the start so the 4.8s timeline repeats seamlessly across four 1.2s tweens.

I'm now working out the dot animation so each dot bounces with a staggered delay but still fits exactly within the 4.8s loop, trying to avoid stagger offsets that push past the loop boundary and break the seamless repeat.

I'll add opacity fading alongside the bounce, with each dot tweening up and back down over 0.7s staggered by 0.12s, repeating indefinitely without creating duplicate instances. I also need to set initial positions for the shapes, centering them absolutely within their container using negative margins.

For border radius, GSAP can interpolate between "8px" and "50%" directly through its complex string handling, so morphing between square and circle shapes should work fine. Now I'll add the control buttons and a state label, then update the button text accordingly.

I'm checking the timeline math for the shape tweens, confirming each state transition lands at the right offset (0, 1.2, 2.4, 3.6) and the full sequence wraps up by 4.8 correctly.

For the dots, I'm verifying their opacity/scale yoyo tweens finish well within the overall timeline, since yoyo naturally reverts them to starting values. I need to drop that odd `tl.set` line and just rely on the shape tweens to define the total duration rather than forcing it artificially.

I'm also double-checking the geometry — shape sizing, offset positions, and scaling — to make sure everything stays visible on stage, then I'll remove that stray line and test the result.

Only one shape appears in the screenshot because all three shapes start absolutely centered with identical margins, so they fully overlap at state 0 with the yellow shape covering the others — that's an initial design issue I should fix by offsetting their starting positions.

The timeline math checks out: the morph loop cycles through states 1→2→3→0 ending at 4.8s with the dot animations finishing well before that, so timing isn't the problem. The fix is to give state 0 distinct offset positions (like s1 and s2 spread apart with s3 centered) while making sure the loop's final state matches this new state 0.

Given my limited remaining budget, I'll make this quick adjustment to state 0 and verify with a single screenshot rather than extensive testing.

Comparing the two screenshots, the dots look identical at both timestamps since they're at opacity 0.35 with a yoyo tween — I can't confirm from the screenshot alone whether the animation timing is actually working as intended.

The timeline math checks out though: states cycle correctly from 1,2,3,0 and loop back seamlessly, with the dots tween finishing well before the full timeline duration. Since I can't fully verify playback behavior from static screenshots, I should do one more quick test by clicking pause and capturing a screenshot to confirm the pause/resume controls actually work.

Pause looks correct since both frames match, and the dots stay dim at low opacity which seems fine for that moment. I still need to verify Resume and Restart behave properly by checking the timeline state through the loader object.

Since inspecting the DOM doesn't expose the timeline time directly, I'll just proceed with clicking Resume and Restart and compare the resulting screenshots.

Resume looks correct, with the dot lift animation and yoyo repeat timing working out to 0.7s total. I'm verifying the morph loop timeline pins each segment at 0.9s intervals ending around 4.8s, which checks out structurally.

Restart correctly resets to the start pose before resuming animation, so that checks out. I'm verifying timing: each dot tween with yoyo takes 0.7s total, and the last one finishes at 1.48s, comfortably within the 4.8s window, so the sequencing holds up.

The segment loop cycles through states 1,2,3,0 and seamlessly returns to the start, keeping the full loop at 4.8s which fits the 3-6s target. A trailing zero-duration callback at the end is harmless, and leftover warnings from the sandbox iframe aren't something I need to worry about. I haven't visually verified the staggered dot motion in detail or tested smaller viewport resizing, but I'll wrap up and report what I've confirmed.
