Create a finished 4:3 landscape type-specimen poster, not a logo. Exact rendered text: “RAINBOW BUBBLE TYPE” “A–Z / FULL SPECTRUM” “A B C D E F G” “H I J K L M N” “O P Q R S T U” “V W X Y Z” “EVERY LETTER, EVERY COLOR” Composition: a pale sky-blue poster field with generous clean margins. At top, set “RAINBOW BUBBLE TYPE” in small condensed white uppercase lettering, centered; beneath it set “A–Z / FULL SPECTRUM” in smaller deep-violet uppercase. The center 68% of the canvas is a precise five-line alphabet grid, each character large, evenly spaced, front-facing, and fully readable. Design every A–Z character as a bold rounded custom display glyph with extreme pneumatic balloon inflation, circular bowl counters, rounded hemisphere terminals, and thick consistent strokes. Each individual letter contains its own complete vertical ROYGBIV gradient: red at its top edge, orange upper zone, yellow and green across its middle, blue and indigo below, violet at its bottom edge. Do not distribute one color per letter and do not run one gradient across the alphabet. Render a clear candy-lacquer skin: spherically convex volume, crisp near-white circular specular highlight at each raised apex, soft internal reflections, thin violet contact shadow beneath every glyph. Place a small rounded violet footer strip at the bottom with “EVERY LETTER, EVERY COLOR” in white uppercase. Stage the lettering against bright cyan-blue sky with subtle warm sunlight from upper right, soft rainbow balloon bokeh near the outer edges only, sparse multicolor confetti floating in the negative space, and a few tiny sun flare points. Keep the grid unobstructed; no overlapping props, no dark background, no extra words, no distorted or missing letters. High-resolution commercial type specimen, clean vector-like geometry with ray-traced glossy 3D surfaces.
