"RETRO" is a YouTube thumbnail for a synthwave music channel, in an 80s neon style. Italic letters with a pink-to-cyan gradient sit above a thin neon rule and the channel name, over a glowing purple grid. Remake it with your own word and channel name.

Create a 16:9 YouTube thumbnail for a synthwave channel. Near-black midnight background with a low horizon at 58% height and a sparse dark-purple retrowave grid receding toward one central vanishing point. Render the exact headline text "RETRO" across the center, occupying 78% of the canvas width. Custom all-caps volumetric arcade-sign lettering: extra-wide geometric block forms, rounded outer corners, tight but readable spacing, thick continuous strokes, solid 3D extrusion angled slightly down-right. The front faces emit a hot-magenta-to-electric-cyan gradient, brightest at each letter center; edges release a soft neon halo. Side faces are darker violet emission with narrow sunset-orange highlights on the lower bevels. Every letter has clear front and side planes, with deep soft cast shadows beneath; magenta and cyan light bleed visibly contaminates the grid and near-black background around the word. Set the exact supporting text "OUTRUN FM" centered below the headline at 73% height, small but crisp, custom condensed uppercase letters in electric cyan neon tubing with generous tracking. A thin hot-magenta horizontal light streak separates the two text levels. Keep the upper-left and upper-right corners dark and uncluttered for YouTube UI readability. No logos, no people, no extra words, no illegible text. Premium ray-traced CGI, volumetric glow, sharp typography, high contrast, clean 1980s arcade-title geometry.
