Create a finished square podcast-cover logo composition for a futuristic technology-and-culture podcast. Render all typography accurately and exactly as quoted. Deep teal-to-black cinematic key-art field with a near-black lower half, fine film grain, shallow edge vignette, thin atmospheric haze, and a bright horizontal anamorphic lens flare crossing behind the title at mid-height. At center, build the dominant two-line title: “CHROMA” above “SIGNAL”. The lettering is broad-proportion classical serif capitals: heavy visual weight, strong thick-thin contrast, deeply cut V-wedge serifs, clean cut-angle terminals, generous tracking. Each letter has a carved pale-silver stone core with sharp bevels, iridescent chromatic oil-slick edge diffraction in cyan, electric blue, violet, and hot magenta; ray-traced internal edge reflections and narrow white key-light highlights. The chromatic finish follows the letter edges and bevel planes, never obscuring legibility. Make the title occupy 55% of the square, centered, with a subtle forward extrusion and dark shadow separation. Above, a small spaced all-caps eyebrow reads “A FUTURE FREQUENCY PODCAST” in crisp condensed sans serif, pale cyan. Below the title, a single fine cyan waveform line stretches 70% of the width, interrupted by a small circular broadcast icon at center; under it, set “NEW EPISODES WEEKLY” in tiny tracked capitals. Behind the lettering, place an abstract translucent chrome orbital ring and a faint distant gridded city-light horizon, both secondary and partially obscured by haze. Strong upper-left cyan key light and lower-right magenta rim light define every bevel. Professional streaming key art, photorealistic render, controlled shadow depth, no extra words, no misspelled text, no people.
