Create a print-ready vertical 3:4 typographic poster for a handcrafted wooden-letter sign. Exact text, rendered precisely: "RAINBOW GUM" "HAND-PAINTED WOOD TYPE" "CARVED · COLOURED · SEALED" Composition: the words "RAINBOW GUM" occupy 72% of the canvas width and the central 47% of the frame, stacked on two tightly spaced centered lines. Each letter is an individual thick carved hardwood block with extra-bold rounded display proportions, deep 3D convex faces, hemisphere-rounded terminals, shallow bevelled edges, and visible end-grain on sidewalls. Each individual letter has its own complete vertical ROYGBIV painted gradient: saturated red at its top edge, orange, yellow, green, blue-indigo, then saturated violet at its bottom edge. Never distribute one colour per letter and never run one gradient across the entire word. Preserve fine natural wood grain beneath translucent coloured stain, exposed pale maple grain on bevel edges, clear polyurethane topcoat, pinpoint near-white specular highlights at each convex apex, soft contact shadows beneath every letter. Place the small uppercase line "HAND-PAINTED WOOD TYPE" centered above the title in clean dark cobalt sans-serif. Place "CARVED · COLOURED · SEALED" centered beneath in the same small type. Behind the lettering, show a pale sky-blue screen-print field with a faint warm cream paper fibre texture. Add a shallow tabletop strip along the bottom with scattered curled rainbow wood shavings, a small flat paintbrush with rainbow-stained bristles, and sparse punched-paper confetti; keep these props below the title and never obscure text. Warm sunlight from upper right, crisp white specular points on clear-coated wood, soft amber bokeh circles near the upper corners, high-resolution product-photography lighting, clean print-poster edges, no extra text, no logos, no warped glyphs.
