Square 1:1 typographic key art for a custom monogram study. Center a single dominant uppercase text character, exactly: “R”. Build it as a thick, geometric display letter with hard angular corners: flat horizontal top bar, vertical stem, sharply squared inner counter, clipped 45-degree joints, and a rigid diagonal leg ending in a crisp wedge. Preserve chunky proportions and slightly varied baseline planes in the internal construction, but do not round any letter edges. Render the R as inflated translucent jelly with a candy gradient flowing from bubblegum pink at upper left through lavender and sky blue to mint at the lower edge; taut glossy membrane stretched over the angular geometry, bright rectangular specular highlights, subtle internal refraction, ray-traced reflections, thin pale lemon rim light. The result must read as a hard-cornered R made from pressurized gel, not soft bubble lettering. Composition: R occupies 66% of canvas height, centered slightly above midpoint. Place a small all-caps caption beneath it, exactly: “R / LETTERFORM STUDY”, set in narrow clean geometric sans lettering, dark violet, widely tracked. Add a tiny second line at the bottom center, exactly: “HARD EDGE · SOFT FINISH”, in the same precise sans at much smaller size. Background: clean pastel gradient from pale sky blue upper left to lavender lower right, with translucent floating spheres and tiny four-point sparkle flecks kept only around the outer perimeter; no objects overlap the R or the captions. Add a faint soft elliptical contact shadow beneath the letter, plus a clean white sticker-like halo around its silhouette. High-resolution studio render, crisp edge definition, controlled reflections, legible exact text, no extra words, no logo, no device.
