Create a wide banner with a rounded-corner rectangle for Apple Note header. Base it around a warm brown‑aesthetic palette with subtle gradient transitions (e.g., deep chestnut to soft caramel). Incorporate fine textured elements like light linen or paper‑grain overlay for gentle tactile depth. Keep the composition clean and word‑free. Add a faint organic curve or wave across the width in a slightly darker tone for visual interest. Use subtle shadow or emboss effect on the wave to evoke light from the top‑left. The overall vibe should feel warm, calm, refined — suitable for a “Home” note background in Apple Notes without any text. Aspect ratio 5:1 and width 1500 px. See more
