Content

This is a frame from video footage. Find the single most prominent SUBJECT (person, animal, or object).

IMPORTANT RULES:
- The subject can be a person, animal, pet, vehicle, or any identifiable focal point
- If multiple subjects are visible, choose the one who is most isolated and largest in the frame
- Prefer people over objects where both are present

Return a cropBox that frames this ONE subject:
- THE HEAD IS SACRED: You MUST include the subject's ENTIRE head with AT LEAST 25% of the crop height as empty space above the top of their head.
- Include full body down to feet where visible
- Leave generous margins (~20%) on all sides so nothing is cut off
- Better to include FAR TOO MUCH background than to cut off the head or any body part
- The crop should be portrait-oriented (taller than wide) for a single standing person/subject

cropBox uses normalised coordinates (0-1):
- x: left edge of crop as fraction of image width (0 = left edge, 1 = right edge)
- y: top edge of crop as fraction of image height (0 = TOP of image, 1 = BOTTOM)
- width: crop width as fraction of image width
- height: crop height as fraction of image height

COORDINATE SYSTEM: y=0 is the TOP of the image.
ALWAYS err on the side of too much space above the head, never too little.

If no clear single subject can be isolated, return cropBox with x=0, y=0, width=1, height=1 (full frame).
