Build a square 1:1 podcast cover around the Host Photo Or Central Symbol, set against a full-bleed field of near-black darkness. Make the central visual feel mysterious and cinematic: a narrow keyhole-shaped opening reveals a concentrated shaft of light, with subtle atmospheric haze fading into the surrounding shadows. Use the Accent Color sparingly within the light and small supporting details, keeping the overall palette cold and restrained. Set the Show Name as the dominant text, using a thin, elegant serif typeface with strong contrast and generous spacing. Keep the title clearly separated from the central visual, aligned with deliberate symmetry, and readable when reduced to a small podcast-app tile. Use no more than two typefaces, no tagline, no inner border, no frame, no episode number, no play button, no microphone clipart, no logos, no watermark, and no text touching the edges. Ensure the Show Name is spelled exactly as provided.
Use these details:
Show Name: "The Last Door"
Host Photo Or Central Symbol: "a single keyhole-shaped opening emitting a narrow beam of light"
Accent Color: "icy blue"
