New scene, not a portrait studio and not a rainy alley: a sunny glass greenhouse at late morning. She walks two steps along a gravel path, then tips a plain metal watering can over a bed of leafy plants. Camera: medium tracking shot, eye level, one slow lateral move. Lighting: bright greenhouse sun with leaf shadows. Native audio: birds outside the glass, water from the can, footsteps on gravel. Keep identity consistent. No logos, no readable text, no products, no packaging, no prices, no CTA, no advertising, no watermark, no brand marks.",
