NATURAL PERFORMANCE (default only — every explicit direction above
wins): when no pose contract, immobility contract or shot-text
direction says otherwise, people read as alive in mid-moment —
believable weight shift, hands engaged with something real, gaze on
the target the SHOT TEXT implies; avoid a stiff attention stance (feet
together, arms hanging straight down) and a blank stare into the lens.
If the SHOT TEXT or any POSE/IMMOBILE contract above stages stillness,
death, sleep, unconsciousness, restraint, drill or an explicit
direct-to-camera look, follow THAT exactly — this clause never
overrides it.
