Tiny Pup, Huge Delivery

Create an uplifting vertical video of a tiny corgi delivering a birthday cupcake across a suburban US backyard. Open on a low 18mm wide shot with colorful balloons towering above the puppy, then use a stabilized backward dolly as the corgi waddles toward camera carrying a lightweight cupcake on a safe tray harness. Cut to a 70mm slow-motion close-up of determined eyes, bouncing ears, and tiny paws crossing the grass. Use golden-hour sunlight, soft lens flare, pastel party decorations, crisp realistic fur, and wholesome creator energy. Add a caption: "When the smallest guest has the biggest job." End with friends cheering as the puppy arrives.
