Create a finished 16:9 horizontal birthday banner designed for a TV screen. Render only this exact wording, with no added text: “Happy 50th Birthday Dia!” Place it as one large, centered headline across the upper third, keeping all lettering inside generous TV-safe margins. Use the Party Pop letterform: heavy, firm geometric display capitals and lowercase, slightly softened corners, even stroke weight, open counters, crisp joins, and tight even spacing. Give the letters a smooth glossy coral-to-teal two-tone finish, one clean specular highlight, a thin crisp white keyline, and a soft drop shadow; keep the forms structured, not inflated or balloon-shaped. Below the headline, reserve four equally sized, completely empty landscape photo windows in a clean two-by-two grid. Keep their interiors blank and unobstructed for photos to be added later—no icons, sample images, text, or placeholders. Use simple bright white borders with a subtle soft shadow and enough separation between frames. The four windows should occupy most of the lower two-thirds while remaining distinct and easy to fill. Set the banner on a bold, luminous hot-pink-to-tangerine and turquoise party gradient with saturated violet accents. Place generous clusters of glossy multicolor balloons near the outer corners and edges; scatter dense, small multicolor confetti and sparkling glints around the perimeter, keeping both the headline and all four photo windows clear. Add bright party-light streaks and crisp highlights, with strong contrast and a clean, cheerful screen-ready finish. Keep all important content away from the edges; no dark stage, pale washed-out background, extra wording, or objects inside the photo windows.
