Create a finished adult Christmas mandala coloring page in portrait 3:4 format. Pure white background with crisp, pure black outlines only. No color, gray, shading, hatching, gradients, textures, or solid black areas. Every drawn shape must have a clean, closed boundary suitable for coloring; use one consistent fine line weight throughout, with clear separations and enough open areas for colored pencils or markers. One large, precisely radial, circular mandala is centered on the page and fills about 82% of the canvas, surrounded by a generous clean white margin. At its exact center, draw a bold, elegant snowflake with six balanced arms, built from graceful geometric branches and small enclosed diamond and teardrop shapes. Arrange repeating Christmas motifs in concentric rings around it: poinsettias alternating with holly sprigs, then rounded ornaments with varied simple interior patterns. Keep the repetition symmetrical and orderly, with each motif clearly distinct and fully contained in the mandala. Add delicate snowflake geometry and small leaf forms to connect the rings without crowding them. Fine adult-level detail, but preserve generous, colorable compartments; avoid tiny clutter. Use clean hand-drawn coloring-book line art with smooth, confident contours, uniform black outlines and no filled regions. The page contains no lettering, words, numbers, border, or extra scene. Keep the whole design inside the safe print margins. Strong, immediately legible central snowflake and balanced floral ornament wreath.
