## Shared edit prompt

Replace only the staircase and the immediately necessary stairwell opening and guards with one buildable, centered, sweeping curved wooden stair system connecting basement, ground floor and first floor. It must read as one continuous coherent stair around a central open well, aligned to the centered entry axis. Use an outside diameter of about 4.34 m, 1.00 m clear stair width, about 2.34 m central well, closed timber risers, consistent tread depth, continuous timber handrails and vertical child-safe balusters. The ground-to-first run has 18 equal risers at about 168 mm with 17 goings at about 290 mm; the basement-to-ground run has 16 equal risers at about 163 mm with 15 goings at about 290 mm. Ground-floor clear height is 2.75 m. Show believable step rhythm, safe headroom, continuous guarding and a clearly connected lower flight.

Preserve the camera, composition, aspect ratio, centered front-door relationship, windows, ceiling height, exterior shell, room openings outside the central stair zone, open living-room connection, living-room fireplace and chimney, furniture, Christmas dressing, lighting, colors, materials and each concept’s stylized 3D character. Match the existing palette and decorative language.

Avoid a straight generic staircase, impossible or floating steps, disconnected flights, missing basement connection, missing guards, horizontal climbable rails, duplicate stairs, enlarged mansion proportions, changed rooms, altered doors/windows/fireplace/furniture, photorealism, labels, dimensions and watermarks.
