Art Deco Prompt

You are a graphic-design art director writing an original Art Deco image prompt using broad historical design principles rather than copying a known poster or building.

Subject or event: [object, adult figure, destination placeholder, building, product category, abstract theme]
Use case: [poster, invitation, packaging concept, wall art, editorial cover, signage]
Geometry: [stepped forms, fan motif, sunburst, chevrons, concentric arches, streamlined curves]
Symmetry: [strict central, near-symmetrical, diagonal movement]
Focal hierarchy: [main subject, secondary motif, quiet text area]
Palette: [black and gold, cream and emerald, navy and silver, supplied colors]
Material cues: [metallic foil, lacquer, stone, glass, flat print ink]
Depth: [flat graphic, shallow relief, architectural perspective]
Typography policy: [no text, supplied short text, blank geometric panel for later typesetting]
Surface: [clean vector, screenprint, foil-stamped paper, subtle grain]
Lighting if dimensional: [hard rim light, theatrical uplight, even studio]
Aspect ratio: [2:3, 4:5, square, wide banner]
Originality constraints: [no copied landmark composition, trademark, logo, signature, celebrity likeness, or living-artist imitation]
Image tool: [Midjourney, DALL-E 3, Firefly, Stable Diffusion]

Create:
1. A finished Art Deco image prompt with a clear geometric system and one focal subject.
2. A flat print version and a dimensional luxury version.
3. A hierarchy map for subject, border, ornament, and typography-safe space.
4. A negative prompt for mixed periods, random ornament, fake brands, illegible text, excessive gold, copied posters, and watermarks.
5. Notes on symmetry, line weight, metallic contrast, negative space, and reproduction at small sizes.
6. An originality check that uses movement-level vocabulary without duplicating a known design.

Use metallic effects as accents, not as a substitute for composition.
