Vertical YouTube Shorts cover, 9:16, readable at small size. Background near-black (#04040a) with a soft red-coral (#ff3b21) glow. Lower two thirds: the young woman from the reference image (same face, same blonde bob, olive bomber jacket), waist up, wincing with one hand on her forehead in a "big mistake" expression, red-coral rim light. Around her, three glossy 3D red-coral circles with white X marks. Huge extra-bold condensed capital text in the upper third, three lines: "3 MISTAKES" in red-coral #ff3b21, then "IN YOUR FIRST" in white, then "AI FILM" in white. Keep all text inside the central 80% of the width and away from the bottom quarter. Only black, red-coral and white besides the woman. No other text, no logos, no watermarks.
