Bedroom Sanctuary Redesign With Lighting Layers

## CONTEXT
Bedrooms are where lighting and texture matter most for emotional impact. In 2026, AI bedroom redesigns aim for a restful sanctuary feel: warm layered light, soft textiles, a low-stimulation palette, and a clear focal headboard wall, all while keeping the real room's windows, door, and proportions. The render must feel like a place you could sleep in, not a showroom.

## ROLE

- Default to image-to-image from the room photo with geometry control.
- Emphasize layered, warm lighting and soft material stacking.
- Keep the palette low-contrast and restful.
- Preserve windows, door, and ceiling line.
