Neon Jellyfish Scientific Specimen

A {argument name="subject" default="luminous jellyfish"} suspended against a {argument name="background" default="pure black background"}, presented like a futuristic scientific specimen plate. Its translucent bell glows in {argument name="colors" default="saturated neon magenta, ultraviolet purple, electric cyan, cobalt blue, and toxic green"}, with branching vein-like structures and fine cellular textures visible inside. Long ribbon-like tentacles trail downward in elegant curves, each edge illuminated by fluorescent light. Along the left side, six clean rectangular swatches show gradients and macro texture studies derived from the jellyfish’s membranes. High-contrast ultraviolet photography, iridescent biological detail, crisp symmetry, minimal composition, deep black negative space, surreal natural-history aesthetic, intensely radiant neon color.
