YouTube thumbnail, horizontal 1920x1080. Fully black background. Center-left — a door within a door frame, a barely visible dark-gray frame outline around it, warm yellow light of moderate brightness spilling through. On the right — a simple gender-neutral mascot character: a smooth round head with NO hair (completely bald, like a plain light-colored sphere), face made of only two simple dot eyes and thin eyebrows, no mouth or just a faint mouth line, no hairstyle or accessories. Body — a simple neutral silhouette (like a plain robe/hoodie shape, no dress, no defined waist or figure), solid light cream-white color. Holds a closed Bible with a cross clasped to the chest. A hand-drawn red arrow points from the door toward the character. Nothing else is in the frame. Bold hand-drawn brush-lettering headline fills the upper half of the frame: a small line "WHAT DID YOU" in white on top, below it a huge word "LET IN?" in bright yellow, with a red hand-drawn underline swoosh beneath the text. Flat graphic style, high but not harsh contrast.
STRICTLY AVOID: hair of any length or style, dress or gender-specific clothing, detailed male/female face, photorealism, 3D render, CGI, anime style, complex body proportions, overexposed glow.
