A highly stylized, serpentine aquatic dragon coiling tightly around the solid, central logo text "TRADE CAGE", interwoven with dense, wet, lush greenery associated with underwater caves. — Tight, centered square logo mark designed as a scalable vector emblem, with the dragon functioning as a powerful frame for the text. — Dominant use of deep cyan and vibrant light blue, accented by emerald aquatic greens and mossy highlights. — Eerie, subterranean, bioluminescent glow, creating a spooky and mysterious atmosphere, suggesting deep water. — Clean graphic design, executed as modern vector art with thick, decisive lines and solid color blocks, suitable for a professional brand mark. — Output must be a perfect 1:1 aspect ratio logo; keep text/logos/labels EXACTLY unchanged: "TRADE CAGE"; no rewriting, redrawing, correcting, or adding any text. — Solid, dark, monochromatic background to maximize focus on the emblem.
