Build a tattoo concept studio for collectors and artists.

1. Prompt to concept: describe a subject, pick a style (fine line, traditional Japanese, neo-traditional, blackwork, geometric, watercolor), set placement and size in centimeters, and get four concepts.
2. Placement preview: overlay the design on an uploaded photo of the body part with scale control and skin-tone blending.
3. Stencil mode: generate a pure black, high-contrast line-work version an artist can actually trace, not just a pretty image.
4. Style comparison: hold the same subject across three styles side by side to help the client decide.
5. Partial refine: thicken one outline or simplify one element without regenerating the rest of the design.
6. Artist handoff export: high-res transparent PNG plus the stencil version, with a note that a licensed artist will redraw for skin flow.
7. Theme packs: curated generators for birth flowers, zodiac, and minimalist animal sets as premium content.
