Fern Trace in Amber

Minimal abstract editorial background, 1:1 square, polished digital illustration. One stylized fern fossil impression is recessed into a continuous matte, stone-like surface, curving diagonally from the lower center toward the upper right. Show a slender curved stem and broad, alternating tapered leaflet indentations, clearly an imprint rather than a living plant. Use simple, shallow relief with clean edges, not intricate veins or gritty rock detail. Restrict the palette to deep plum and saturated amber. A soft amber glow rises from the lower edge and grazes the recessed shapes, leaving the upper-left area dark and spacious. Let a few terminal leaflets fade gently into the surface, suggesting an old trace. Strong silhouette, smooth tonal transitions, generous breathing room, no separate objects or landscape. No people, no text, no logos, no watermarks.
