Spark Elements Shuffle Animation

During an onboarding or intro sequence, the central illustration, consisting of a stacked deck of cards and floating circular icons, periodically transitions to showcase different themes. The transition begins with the active cards and icons shrinking and fading inward toward the center. Immediately after, a new set of themed cards and icons scales up and rotates outward with a lively spring bounce. The accompanying text below crossfades to update the title and author, creating a cohesive and playful storytelling experience.
