CENTER SUBJECT: "【가운데 주제】"
Interpret this value visually as the central motif; never print it as text. If the subject line is missing or empty, use a lotus blossom and finish without questions.

PATTERN selected: "【무늬】"
Interpret only the selected choice:
- 꽃잎: Concentric layers of nested petals, leaves, floral arches, scallops, and small botanical ornaments.
- 기하학: Precisely aligned polygons, interlocking angular bands, rosettes, stepped shapes, and geometric compartments.
- 깃털: Symmetrical feather fans, outlined barbs, teardrop eyes, curved plumes, and layered feather-shaped compartments.
- 별 · 달: Repeated stars, crescent moons, celestial rosettes, outlined circles, and symmetrical orbital bands.
If this selection line is missing or empty, use 꽃잎 only.

DIFFICULTY selected: "【난이도】"
Interpret only the selected choice:
- 보통: Medium-density detail, balanced large and small compartments, and comfortably colorable inner spaces.
- 쉬움(큰 칸): Fewer decorative rings, broad shapes, large enclosed compartments, and minimal tiny detail.
- 어려움(촘촘): Many tightly organized rings, intricate micro-ornaments, and small but clearly separated colorable compartments.
If this selection line is missing or empty, use 보통 only.

Make the chosen central subject recognizable inside a circular medallion. Build the surrounding ornament with precise eightfold radial symmetry; preserve the natural identity of the central subject if it cannot itself be radial. Fill most of the page with the mandala while retaining clean print-safe white margins.

Suggest dimensional layering only through overlapping outline geometry, nested contours, and changes in scale. Use pure black strokes on pure white. Slightly strengthen major contours while keeping inner details clear. Enclose all intended coloring compartments and avoid muddy intersections, accidental tangencies, and unusably tiny slivers.

Every compartment must remain unfilled white. No solid black shapes, colored regions, gray tones, hatching, stippled shading, gradients, cast shadows, text, letters, numbers, brands, signatures, or watermarks. Output the flat coloring page directly, without a table, frame, or mockup.
The choice names in this prompt are internal labels only; never print them as text.
