Sora提示词：CRITICAL HARD CONSTRAIN

CRITICAL HARD CONSTRAINT — PRODUCT MUST MATCH REFERENCE IMAGE EXACTLY
The heater must be identical to the reference image. No changes allowed.

Scene: American-style outdoor winter camping at dusk, beside a tent.
Subtle Christmas & New Year atmosphere (soft warm lights, cozy winter mood).

A strong, athletic American man (30s) wearing winter outdoor clothing (jacket, beanie, gloves) walks into the scene holding the heater.

He places the heater gently in the center of the campsite.

Friends are already seated around the tent.
They naturally gather closer, warming their hands and chatting casually.

Environment: outdoor, winter season, slightly cold air, cozy fire warmth contrast.

Camera style: handheld, natural phone-style movement.
Lighting: blue-hour dusk with warm firelight glow.

Style: realistic UGC, lifestyle moment, not commercial, not staged.
