Create a high-resolution (12k)vertical triptych of three Japanese-inspired backgrounds, each panel tall and narrow and presented side-by-side. Use a repeating seigaiha (overlapping semicircle/wave fan) texture as a subtle, desaturated backdrop across all panels. Foreground for each panel: multiple layered, flowing undulating bands that read like stylized ocean waves or rolling hills, composed of very fine parallel contour lines with slight variations in stroke weight. Left panel: cool palette — deep navy, indigo, teal, seafoam, pale mint; gradient transitions from deep blues at the bottom to pale mint at the top. Center panel: soft pastel palette — muted mauve, dusty rose, lavender, cream, soft sage; gentle rise and fall of layered bands, brightest near the mid-top. Right panel: warm palette — sandy beige, warm ochre, terracotta, coral, muted slate; glow toward the top right like warm ambient light. Maintain delicate color harmony between panels so they feel cohesive. Add minimal grain and paper texture, slight vignette, and subtle highlight on top ridges for depth. Keep composition elegant, airy, symmetrical margins, vertical Japanese text block reading "Japanese Pattern" (stylized Latin letters) near the top edge of each panel as a decorative element. Deliver vector-friendly, print-ready artwork with clean crisp lines, transparent layers, and no watermarks.

The image shows a set of three vertical banners with wavy lines in different colors, each with text on them. The banners are arranged in a collage-like fashion, creating a visually pleasing composition.
