Create a polished portrait birthday greeting graphic with the high-energy visual language of racing livery. Night-circuit black fills the background, with a faint asphalt texture along the lower edge and restrained motion haze. Use a single hard white spotlight from above and slightly in front, deep carbon-black shadows, and a decisive red-and-championship-gold palette. Fine white horizontal speed lines trail from the headline and dissolve into darkness; add a few subtle checkered details, but no logos or real-world team marks. Set the exact text “BIRTHDAY GRAND PRIX” as a small, crisp uppercase eyebrow at the top. Make “HAPPY BD” the unmistakable main title, very large and wide across the center. Form each letter from solid sheet metal under saturated racing-red automotive paint: a low, wide display skeleton, extreme forward lean, consistent long slanted stroke cuts, rounded interior joins, closed solid shapes, and tight spacing. Each flat glossy face has a narrow chamfer, with a hard continuous white highlight along its upper edge, dark lower edge, and a close red halo. Keep every letter clean and unmistakably legible. Let the overhead beam create the specular axis and cast sharp shadows backward in the direction of motion. Below the title, show a small celebratory hero object: a compact black racing-tire birthday cake with red and gold icing bands, tiny checkered-flag candles, and bright candle flames. Render it as a tactile, dimensional object, lit by the same overhead beam; it should support the typography without competing with it. Set the exact supporting line “YOUR DAY. YOUR GRID.” beneath the cake in clean, compact white uppercase lettering. At the bottom, add the exact small detail “FULL THROTTLE CELEBRATION” in championship gold. Keep a clear top-to-bottom reading order, generous safe margins, crisp text, and distinct separation between all text tiers. No extra words.
