Create a square Y2K bubbly lettering graphic. Render exactly the Spanish words “Feliz Cumpleaños”, with no quotation marks and no other text. Arrange the phrase on two centered lines, “Feliz” above “Cumpleaños”, with clear spacing between letters and words. Make the lettering the unmistakable hero, occupying about 82% of the canvas width: extremely inflated, near-bursting pneumatic forms, each stroke like a separate rounded air-filled cushion, with fully spherical convex faces and gently pinched edges. Smooth glossy candy-PVC surface, a continuous pastel pink-to-lavender gradient across the letters, strong rounded white specular highlights on the upper bulges, and soft matching inner glow. Keep every letter crisp and unmistakably legible despite the extreme volume. Set the words against a perfectly flat pure black #000000 void, with nothing behind or around the subject. Add a few small glossy hearts and stars floating asymmetrically near the outer edges, never touching or obscuring the lettering. Sweet early-2000s toy-magazine energy, maximum roundness, soft luminous shading, no borders, no extra objects, no additional lettering. Export as a transparent PNG by keying out only the black background; keep the lettering and all hearts and stars unchanged.
