Curved-Grain Wood: Abstract Close-Up Background

Photorealistic macro close-up of wood texture focusing on curved grain. An abstract, seamless tileable background with flowing S-curves and wavy grain lines, high detail at the micro level including fine pores and subtle growth rings. Warm natural colors ranging from honey gold to walnut brown with hints of reddish tones. Light comes from the top-left in soft, directional rays to create gentle highlights and fine shadows along ridges, giving a tactile, almost glossy surface. The composition should be tileable in both horizontal and vertical directions, suitable for background design; crisp enough for 8K or higher resolution, with slight bokeh in the background if rendered in a photo style. Style: photorealistic, macro texture, and digital painting blend optional; aspect ratio 1:1 or 16:9.
