Glasgow School Gesso Panel (Style-Only, Image-Conditioned)

Re-render this image as a Glasgow School decorative gesso panel, drawing on Charles Rennie Mackintosh's long vertical geometry and Margaret Macdonald's raised plaster relief, circa 1900. Keep the subject's position and proportions intact. Translate its contours into elongated, gently simplified forms with pencil-thin charcoal borders and a few deliberate vertical lines extending through the background. Build highlights physically: spread pale gesso with a narrow spatula in shallow ridges, then trace rosebuds and slim stems in low relief near the margins. Use a palette of chalk white, pale mauve, muted sage, pearl gray, and one faint blush-pink accent. Let the relief catch light from one side, creating soft real shadows no darker than the subject needs. Place a spare ladder of evenly spaced squares behind existing gaps in the composition, never across a face or focal detail. Show the material as hand-smoothed plaster on a lightly woven ground, with small uneven edges and isolated pinholes. The panel should feel simultaneously architectural and intimate, not a glittering fantasy illustration. At thumbnail scale, the subject should still dominate the long geometry and rose motifs. Leave a calm, uncluttered band of negative space along the top or bottom edge where a title could sit. Strictly no on-canvas text, no legible lettering, no signature, no watermark, no logos. Preserve the subject, pose, and composition of the source image exactly, change only the medium and rendering. Aspect ratio matches source.
