Create a finished square logo graphic for a college Bubble Bar on a pure black background. Center the complete lockup with generous clear margins. Set the exact headline text “GECJ” large across the upper-middle, about 78% of the canvas width. Below it, set the exact supporting text “Bubble Bar” centered, clearly readable and substantially smaller. Do not add any other words, letters, numbers, or logos. Render “GECJ” as custom, extremely inflated 3D display lettering: heavy, rounded, tightly spaced forms, each stroke bulging outward like a pressurized spherical volume, with clean, unmistakable letter shapes. Make the letters mirror-polished chrome, not colored plastic: reflective silver surfaces with sharp white studio highlights and dark reflections from the black environment. Place crisp circular specular highlights near the top-center of each convex stroke; use strong edge reflections to define the inflated curvature. Deep ambient occlusion in the narrow gaps between letters and a soft shadow beneath the lockup give it depth. Render “Bubble Bar” in a compact, bold rounded sans serif with a polished chrome finish, subordinate to the headline but fully legible. Add a few small, separate chrome bubble spheres around the outside edges of the lettering as a restrained supporting motif; keep them clear of the text and leave the black negative space uncluttered. Overhead studio key light, controlled white rim reflections, physically based ray-traced metal reflections, high-contrast black-and-silver palette, crisp 3D edges, polished product render. Keep both text lines centered, correctly spelled, and unobstructed. No gradients, colored candy hues, extra props, photographic scene, borders, or watermark.
