A cheerful, bright overhead flat-lay photograph of the word "HAPPY" spelled out in large inflated foil balloons, each letter roughly 50 cm tall, resting on a white floor. The balloons are the classic mylar party-letter type — glossy, metallic, and inflated round so each letter puffs outward in every direction. Color scheme: alternating gold-metallic and hot-pink-metallic balloons, letter by letter. Shot directly from above with a 24mm lens, f/5.6, even bright daylight fill. Each balloon letter shows specular highlight arcs across its curved metallic surface, with strong mirror reflections of the white room and photographer. Small foil stars and confetti dots are scattered around the balloons on the white floor. The word "HAPPY" reads clearly top-to-bottom in the frame, all five letters fully visible.
