536Mechanical Insect Atlas

Output size 1080x1350 pixels, 4:5 portrait, Instagram standard.
Generate exactly one finished antique illustrated mechanical-insect atlas plate. Fill the canvas edge to edge with the plate itself, never a photograph of a book, mockup or framed print. Default ratio 4:5, overridden by the size instruction.
Selected insect: 【Insect】. Selected palette: 【Color】. Blank insect defaults to butterfly, blank palette to sepia. Choose-for-me commands select one listed option and are never printed. Butterfly has two broad pairs of translucent wings; beetle has split hard wing cases and a compact armored body; dragonfly has two narrow pairs of veined wings and a long segmented abdomen. Draw exactly six articulated legs and two antennae, with coherent attachments. Show only the chosen species.
One large complete insect dominates roughly two thirds of the canvas. Surround it with three small detail studies of its own wing joint, spring chamber and gear core. Invent interlocking brass gears, bronze ribs, tiny rivets and wound springs. These are fictional decorative mechanisms, not buildable engineering instructions. Fine leader lines reach the corresponding parts without crossing lettering. Keep a dense but readable hierarchy, precise metal junctions and translucent wing membranes. Invent a new pose, part arrangement and detail-study placement, without copying a reference specimen or composition.
Sepia uses warm ivory parchment, brown engraved shading, honey brass and delicate amber watercolor washes. Bronze uses cool pale parchment, bronze volume, verdigris recesses and fine stippled shading. Black and white uses strictly neutral ivory, black and gray crosshatched engraving, representing brass through tonal contrast without colored highlights. All remain antique fantasy specimen illustrations, with distinctive mood and mark-making for each palette, never photorealistic product renders.
Print exactly these four strings: "Haru", "Wing pivot", "Spring chamber", "Gear core". Render the first string once as a modest collection heading between the upper 12% and lower 15% of the canvas. Render the remaining three strings once each as small legible labels next to their corresponding part studies. Copy spelling, spacing and script exactly; no other text, numbers, dates, invented pseudo-Latin or illegible decorative writing. Proofread each character and every leader line. No actual brands, logos, commercial product designs, known characters, people, signatures or watermarks. Return only one finished illustration without explanations, code or questions.
