Minimalist Paper Fold Tea Commercial Poster

A single 4:5 vertical minimalist commercial poster for a fictional oriental tea brand. Subject and setting: A vertically oriented sheet of warm-white Xuan paper folding upward from the bottom into three layered folds of varying heights, evoking abstract mountain ridges while displaying realistic paper thickness, fibers, and creases. On the lowest fold sits a small [dark brown] teapot; on the middle fold, a delicate [white porcelain] tea cup; on the highest fold, a few scattered [dried rock tea leaves]. Composition: Objects are realistically scaled and non-overlapping. A thin, restrained wisp of [amber] tea smoke rises from the teapot spout, meandering along the creased paper ridges toward the cup, resembling delicate ink wash brushwork with subtle density shifts. Typography: Vertical modern Song typeface on the right negative space displaying the main title "[Mountain Field Entering Cup]", with small vertical text "[Lan Xu]" at the top right and small text "[Rock Tea]" at the bottom right. Lighting and color palette: Soft directional studio lighting casting gentle shadows along paper folds; palette consists of warm white, rock brown, tea amber, and minimal ink black. Constraints: Clean commercial layout, no people, no ancient costumes, no full-screen realistic landscapes, no ornate calligraphy, no gold foil, no watermarks, no multi-grid collage.
