/***********************************How It Works:
• 	Each scene is a separate function (, , )
• 	A timer switches scenes automatically
• 	Animations update every 50ms for smooth motion

💡 Why It’s Special:
• 	Visually expressive and easy to understand
• 	Modular and expandable (OLED captions, buttons, etc.)
• 	Perfect for storytelling, student demos, or poetic displays
