Narrator: "Circle. Round and round. Circle is for Orange." Circle gains texture and a tiny stem, becomes a smiling orange, bounces once. Word "ORANGE," highlight shape outline in orange. 0:04–0:07 | Square is for Gift Box: The orange rolls and reshapes into a square. Narrator: "Square. Four equal sides. Square is for Gift Box." Square gains a ribbon and bow, wiggles playfully. Word "GIFT BOX," highlight in purple. 0:07–0:10 | Triangle is for Mountain: The ribbon folds into a triangle. Narrator: "Triangle. Three sides. Triangle is for Mountain." Triangle grows a snowy peak and a small smiling sun beside it. Word "MOUNTAIN," highlight in brown/teal. 0:10–0:13 | Star is for Sky: The mountain peak stretches into a star. Narrator: "Star. Star is for Sky." Star twinkles softly with tiny sparkles floating around it, gentle glow pulse. Word "STAR," highlight in golden yellow. 0:13–0:15 Recap: Orange, gift box, mountain, star line up in four tiles with shape outlines above. Mascot points to each in sequence. Narrator: "Circle, Square, Triangle, Star. Great job!" Sparkle + warm chime. Requirements: Each shape fully visible before morph, uppercase-clarity level precision on shape edges, no warped or duplicated forms, gentle motion only, synced sound cues, calm and beautifully polished finish.
