Re-render the surface texture of this exact selected A as a single scanned frame of high-speed Super 16 colour-negative film. This is a deliberately grain-forward photochemical texture study. Make organic dye-cloud grain unmistakable at normal full-image viewing size, distinctly stronger and more film-like than the previous r4. Build the texture from irregular, softly bounded translucent variations of colour density at several small scales. Shapes, sizes, spacing and opacity must vary naturally. Let grain have stronger presence in midtones and shadow regions and subtler presence in bright highlights, while remaining clearly visible across smooth sky, skin and fabric. Use primarily luminance texture with restrained, naturally correlated colour-density variation. Integrate the grain into the image's tonal transitions, with gently organic fine-detail microcontrast; preserve readable eyes, facial features, the pendant and costume design. Keep the original illustrated character, exact composition, light direction, shadow shapes, overall colours and brightness. Do not make the figure photorealistic. Avoid regular pointillist dots, uniformly sprinkled noise, sand or paper texture, material-only roughness, isolated coloured specks, muddy blobs, digital sharpening halos, dust, scratches or damage. No new objects, colour grading, halation, vignette or defocus. Render one finished 16:9 image with convincing, visibly pronounced film-emulsion grain.
