Affiche Styllo-Plume et Trait d'Encre

A 4:5 luxury commercial still life promotional poster. A [dark ink-green metallic] fountain pen lies diagonally from the upper right toward the lower left, its open cap resting parallel in the upper right corner and its gold nib positioned at the center of the frame. Beneath the pen, a continuous strip of [warm white cotton paper] enters from the top left and descends through three wide folds in a Z-shaped path. A rich blue-black ink line flows from the nib along the center of the paper ribbon: starting as a precise thin hairline, expanding into a broad wash on the second fold, splintering into dry brush strokes on the third fold, and naturally resolving into the handwritten cursive word "[TRACE]" at the lower left. The ink pools realistically at paper creases without bleeding off the edges. Three tiny, minimalist embossed labels reading "[NIB]", "[FLOW]", and "[PAPER]" sit subtly along the paper margins without frames or arrows. Setting and Style: Close-up product still life photography set against a [matte dark cyan desktop]. Directional soft studio light from the upper right illuminates metallic reflections on the pen barrel, intricate nib engravings, and tactile paper fiber texture, casting deep, soft shadows toward the lower left. Color palette limited to dark cyan, warm white, blue-black, and refined gold accents. Full opaque frame, no hands, no ink splatters, no external logos.
