Create a contemporary 9:16 mobile poster for a New Year celebration in a lived-in Qassim courtyard workspace in soft morning light. Use restrained editorial geometry, generous negative space, elegant fireworks, light confetti, and a professional festive mood rather than visual clutter. Build the palette from , , and . Reserve one clean blank headline field for the exact source headline “Happy 2026!” and a separate clean blank brand field for ; both fields must remain empty in the generated pixels and receive verified copy through professional post-typesetting after generation. Suppress all generated text, letters, numbers, logos, wordmarks, signatures, and watermarks. Keep the final composition crisp at 1080 by 1920 pixels, legible on a phone, culturally neutral within a Najdi setting, and suitable for a premium organizational greeting.
