IMMOBILE BODIES OBEY GRAVITY: a person who is dead or unconscious
exerts NO muscular effort. Every part of their body — head, torso,
arms, hands, fingers, legs — rests fully on whatever supports it
(floor, wall, furniture, their own lap) and hangs or slumps with
gravity. NEVER show any part of an immobile person's body lifted,
raised, held up in the air, or posed as if presenting something:
an object in their grip stays clenched in a hand that itself lies
fallen on a support — the hand does not hold the object up. If the
canonical pose leaves a body part unspecified, resolve it as the
most gravity-compliant, fully-supported position.
