You are a professional photographer on a seaside promenade at golden hour. Create a high‑resolution photograph (8K, 16:9) that looks like it was captured with a full‑frame 50mm f/1.8 lens on a Canon EOS R5. Scene: calm ocean, wet sand foreground, distant horizon with sun dipping below water. Lighting: warm golden‑hour, rim lighting on silhouette, soft backlight on water, subtle lens flare right side. Composition: rule of thirds, horizon on upper third, wooden boardwalk leading left to horizon, shallow depth of field with bokeh. Mood: serene, contemplative, slightly nostalgic. Details: faint silhouette of lone figure in light jacket, scattered seashells foreground, sky gradient orange to purple. Technical: 8K, 16:9, photorealistic, no watermarks, no text overlays.
