Create a finished square podcast cover for a true crime podcast, designed to read clearly at small thumbnail size. Pure black background. Main headline, centered and dominant, rendered exactly as three stacked lines: “COLD” / “BLOODED” / “CASES”. Use broad, irregular hand-painted letterforms with variable stroke widths, uneven blood opacity, dark dried crust along stroke edges, and small gravity-pulled drips breaking from the heaviest strokes. The letters are made of dense, viscous deep-crimson blood; thin areas catch arterial-red highlights, thick accumulations deepen to near-black clot. Show realistic surface tension at rounded drip terminals, glossy specular highlights, subsurface red glow at the edges, and dark pooling beneath the strokes. Keep every letter unmistakable and the full title unobstructed. Below the headline, set the exact supporting line “A TRUE CRIME PODCAST” in small, condensed uppercase lettering, pale bone-gray ink, with clean spacing and high contrast. Set “REAL CASES. UNANSWERED QUESTIONS.” beneath it, smaller but legible, in the same bone-gray lettering. Add a restrained scene prop in the lower-left: a blackened evidence envelope with a partly visible fingerprint impression and a dark-red blood smear, no legible writing, no numbers, no extra text. The prop stays secondary to the title. Maintain a pure-black field with ample separation around all text. Directional dim red side light catches the wet blood; subtle neutral-gray edge light reveals the envelope and fingerprint without introducing colorful decoration. Photoreal practical-effects blood, tactile dried edges, controlled high-contrast lighting, crisp text, no additional words, no logos, no watermark.
