Seine II Console

Edit the FIRST input image - a 2x2 grid of rough 3D turntable
renders of the same product - into ONE composite 2x2 grid of clean
studio "silo" product photographs. Same layout, same cell mapping.

HARD CONSTRAINTS (non-negotiable, apply to every cell):
  - BACKGROUND: ALWAYS PURE FLAT WHITE #FFFFFF. NEVER ANY OTHER
    COLOUR, TINT, GRADIENT, VIGNETTE, FLOOR, GROUND, SURFACE, WALL,
    SCENE OR PROP.
  - NO BORDERS. NO FRAMES. NO OUTLINES AROUND CELLS OR AROUND THE
    SUBJECT. NO LINES, RULES OR DIVIDERS BETWEEN CELLS. NO GUTTERS,
    PADDING OR MARGINS - CELLS ARE EDGE-TO-EDGE.

SUBJECT: Seine II Console

INPUT IMAGES (in order):
  1. FIRST input - a 2x2 grid of rough 3D turntable renders. Each
     cell defines the camera angle, framing, perspective and aspect
     ratio for the corresponding output cell. Use the rough geometry
     for POSE ONLY - ignore its colours, materials, lighting and
     low-poly artifacts. If geometry conflicts with the reference
     photos, trust the references.
  2..2. Real photographs of the actual product - APPEARANCE &
     STRUCTURE GROUND TRUTH. Every cell must show this same product:
     matching colours, materials, finishes, proportions, joinery,
     hardware, cushion shapes, frame geometry, distinctive details.

CELL MAPPING (row, col -> camera angle):
  - row 1, col 1: 50 deg turntable view
  - row 1, col 2: 125 deg turntable view
  - row 2, col 1: 235 deg turntable view
  - row 2, col 2: 305 deg turntable view

CROSS-CELL CONSISTENCY (CRITICAL): every cell shows the exact same
physical object - identical materials, colour, finish, proportions,
lighting, exposure and scale. ONLY the camera angle changes between
cells. Zero appearance drift between cells.

OUTPUT REQUIREMENTS:
  - Same 2x2 cell layout as the input grid; cells edge-to-edge.
  - GRID GEOMETRY (CRITICAL): the output is an EXACT 2x2 grid of
    EQUAL cells split at exact halves - every row the same height, every
    column the same width, matching the input grid's cell boundaries
    one-to-one. Each product sits FULLY INSIDE its own cell, centered,
    framed exactly like the corresponding input cell, with clear margin
    on all four sides. NOTHING is cropped, cut or clipped by a cell edge
    or the image border - no product may straddle two cells or spill
    past the frame. The bottom row must be as complete and full-height
    as the top row.
  - REPEAT: ALWAYS WHITE BACKGROUND (#FFFFFF), NO BORDERS, NO FRAMES,
    NO LINES BETWEEN CELLS, NO NUMBERS, CAPTIONS OR TEXT ANYWHERE.
  - Strictly forbidden: any logo, brand mark, text, label, signage,
    watermark, sticker, tag, packaging copy or letterforms on the
    product or in the scene.
  - Sharp focus, soft diffused studio lighting, identical in every
    cell. A single soft neutral contact shadow beneath the subject
    in each cell.
  - Output ONLY the composite 2x2 grid image.
