Same Sea Different Light Diptych

Goal: Create a calm aesthetic diptych wallpaper comparing the same seascape in two visual languages: realistic ocean photography on the left and minimalist charcoal-and-red ink illustration on the right.

Canvas: Wide horizontal 16:9 composition, split exactly into 2 equal vertical panels with a sharp center divide and no outer border.

Left panel: A realistic telephoto photograph of {argument name="seascape subject" default="deep blue ocean waves with a pale full moon half-rising on the horizon"}. Use layered rolling waves in the foreground, white sea foam, a dark horizon line slightly above center, and a muted blue sky. The moon is a single pale cream disk, partially hidden behind the horizon, centered slightly right within the left panel. Color palette: teal blue, cyan, deep navy, white foam, soft cream moon. Mood: quiet, early morning, still and contemplative.

Right panel: Warm off-white textured paper background with a small minimalist charcoal drawing positioned slightly right of center and slightly below mid-height. The drawing contains exactly 3 main visual elements: 1 red semicircle sun, 1 thin black horizon band, and 1 group of rough black wave strokes beneath it with sparse red accents. The illustration should feel hand-drawn with dry brush, charcoal pencil, and ink scratches, leaving large negative space.

Text content: Add exactly 1 small italic serif caption beneath and left of the illustration reading “{argument name="caption text" default="same sea\ndifferent light"}” in dark gray or black, split across 2 lines. Add exactly 1 short thin red underline below the caption.

Style: Quiet editorial art print, red-and-black charcoal aesthetic, subtle paper grain, poetic minimalism, balanced asymmetry, muted colors, no people, no boats, no extra text, no watermark.
