Design a 3:4 vertical typographic specimen poster on a bright white paper field. Render the exact supplied lowercase alphabet as three centered lines, quoted verbatim: "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". Make this the only text. Build every character as original Gothic stained-glass lettering: each lowercase form has a tall, narrow black lead-came outline, pointed medieval terminals, restrained uneven hand-drawn contours, and a readable open counter. Divide each letter into 3–6 irregular hand-blown glass cells using thin internal lead lines; cycle ruby red, sapphire blue, emerald green, amber gold, violet, and cyan across the alphabet without repeating adjacent colors. Glass is translucent with tiny seeded bubbles, faint ripples, darker pigment at the perimeter, and bright transmitted cores. Arrange the lines in a precise centered grid with generous tracking and wide white margins; first line at upper third, second at center, third at lower third. No title, no border, no extra symbols. Illuminate from behind and slightly above with clean daylight: crisp white ground, sharp highlight flecks along the black lead edges, soft colored transmitted-light pools and small prismatic caustic fans directly beneath each glyph. High-resolution editorial poster photography, orthographic front view, sharp focus, clean negative space, physically accurate stained-glass transmission and refraction.
