Diwali is the night the subcontinent trades electric glare for a thousand little clay flames. This system bottles that moment: rows of diya lamps burning molten gold against a deep indigo-purple sky, marigold garlands ablaze, and the floor blooming with rangoli — mirror-symmetric powder patterns radiating from a center like a mandala drawn in sugar and chalk. Light is the material; darkness is the canvas. Every surface can hold a flame, and every flame deserves a pattern worthy of it — warm hand-made ornament laid over cool night.
