### Full prompt
```text
A dual-orientation optical illusion portrait. When viewed upright (0° orientation), the artwork clearly depicts [a young woman's left-facing side profile]. When rotated 180 degrees upside down, the exact same composition reveals [an elderly woman's side profile]. Both figures share identical contour lines and spatial boundaries with no split screens, overlays, or separate drawings. The transformation relies entirely on contour reinterpretation and structural ambiguity: the young woman's chin functions as the elderly woman's nose upon rotation; the young woman's ear forms the elderly woman's eye socket; the young woman's neckline forms the elderly woman's mouth and chin. Style: Moiré interference pattern rendered with ultra-thin radial or dual-frequency vector lines across the composition, creating optical depth without breaking the illusion. Strict monochrome palette with pure black background (#000000) and sharp white to light gray linework. Tonal gradients created solely through line density. Ultra-precise vector alignment, razor-sharp silhouette edges, no blur, no texture noise.
