Frame-by-Frame Verification for UI Card Animations

Choreograph a GSAP timeline for UI cards with strict timing constraints: 280ms for cards, 220ms for titles, 160ms for metadata, and a 60ms stagger between elements. Then use Playwright to step through the animation frame by frame, capture screenshots for comparison, catch problems like overshoot, and patch the code iteratively until it passes—all without rewriting everything from scratch. Ideal for UI motion tutorials and front-end workflow write-ups.
