First frame matches the provided Christmas bedroom.

A young British blonde woman in modest cotton long-sleeve top and pajama pants.

0-2s Wide shot entering the room; she approaches the bed holding the duvet.
2-5s She gently shakes and spreads the duvet across the bed (big movement, natural, safe).
5-8s Medium-wide shot: she smooths the duvet with both hands.
8-11s Close-up: her hand glides across the microfiber surface, showing softness.
11-15s Wide top-down shot: she adjusts pillows and presses the duvet flat with both hands.

Voiceover (British accent):
“This duvet feels so soft and comfortable… perfect for every season.”
