The primary face must be centered inside an invisible safe zone (not drawn), and a title logo (derived from title_text + title_style_preset) must be placed inside the same safe zone. composition: > Aspect ratio 3:1. Invisible safe zone (DO NOT draw it): - Left margin: 15% of width - Right margin: 15% of width - Top margin: 16% of height - Bottom margin: 16% of height Keep the entire face AND the entire title logo fully inside this safe zone. Background may extend to the edges. action: > Place the reference image content with maximum fidelity. Auto-crop/scale/reposition to fit a 3:1 banner with no stretching. Detect the primary face (if multiple faces, pick the largest/most prominent). Center the primary face within the safe zone both horizontally and vertically. Never crop off the face/eyes; keep the full face comfortably inside the safe zone (not near edges). Face zoom behavior: - If face_zoom is OFF: keep the original framing as much as possible while still centering the face in the safe zone. - If face_zoom is ON: zoom/crop to a bust-up portrait centered on the face (head and shoulders visible; include upper chest; do not crop the top of the head or chin; keep facial features prominent). Create negative space inside the safe zone for the title logo by adjusting crop/reposition/out"
