Based on the user's [Theme Text] and [Image Aspect Ratio], create a highly polished "Monochrome Optical Concept Poster".

[User Input]
Theme text: [custom]
Aspect ratio: [custom as needed]

This is not an ordinary text poster, not a simple typographic poster, and not a figurative illustration. It is a high-quality concept poster centered on the theme text, fusing Black-and-White Op Art, parametric generative graphics, biomorphic abstraction, and experimental Swiss-style typography. It must carry strong visual impact, modern design sensibility, abstraction, order, philosophical weight, and a unified serial style.

[Overall Style]
1. Predominantly monochrome black and white; background is clean off-white, warm white, or very light grey paper texture.
2. The hero visual should be a high-contrast abstract graphic language combining optical illusion, mirror symmetry, ripples, repeating curves, parametric arcs, radial lines, moiré patterns, concentric lines, dot grids, distorted checkerboards, fluid forms, feather/wing-like structures, nodes, circuits, paths, and energy fields.
2. Graphics must not be mere decoration — they must semantically echo the theme text, as if explaining the mood, structure, tension, or relationships of the theme.
4. Style should lean toward high-end graphic design, experimental posters, futuristic visual archives, design-exhibition posters, conceptual album covers — avoid commercial promo, cheap, or generic social-media template feels.

[Headline Requirements]
1. The theme text is the most important headline; place it at the center or core visual zone with large size, strong legibility, and dominant visual presence.
2. The headline must render accurately — no typos, missing characters, or wrong characters.
3. If the theme text is Chinese, lead with a large Chinese headline and optionally add a small English subtitle or explanation; if the theme text is English, lead with the English headline and optionally add a small Chinese support line.
4. Headline typography should be modern, restrained, and powerful — suitable for a high-end design poster. No cartoon feel, no over-decoration.

[Composition & Visual Structure]
1. The image should have a clear "central order". Pick one of the following structures based on the theme:
   - Symmetric confrontation
   - Central-axis burst
   - Two-way collision
   - Resonant convergence
   - Node-path
   - Vortex circuit
   - Ritual exhibition
2. For themes leaning toward conflict, opposition, contest, struggle, predicament, or historical tension — use left-right impact, dual-core confrontation, central collision, splitting and pulling structures.
3. For themes leaning toward fusion, symbiosis, resonance, connection, harmony, or order — use mirror echoes, centripetal convergence, ripple resonance, interlocking structures.
4. For themes leaning toward thought, cognition, systems, decision-making, philosophy, or mechanisms — use nodes, connecting lines, circuits, paths, balanced structures, or parametric-diagram organization.
5. The hero abstract graphic should be strong enough to stand alone as the poster's signature mark, but not overpower the headline.

[Typography & Information Hierarchy]
1. Beyond the headline, add a small amount of supporting typography to enhance the archive / exhibition / concept feel, such as:
   - Small English keywords
   - Small Chinese keywords
   - Vertical side notes
   - Top or bottom navigation-style short words
   - Short slogans
   - Structure labels
   - Symbolic captions
2. These supporting elements should be auto-generated around the theme — short, small, refined, not paragraphs, not article-like.
3. Optionally add dots, lines, crosses, asterisks, rings, grids, coordinate-style symbols, and minimal icons to enhance the systemic and experimental feel.
4. The layout must breathe with whitespace — never overcrowded — yet have enough information density to feel "design-rich but not chaotic".

[Theme-to-Visual Translation Logic]
1. Don't just stamp the theme text onto the page — translate it into a visual metaphor.
2. For example:
   - If the theme has conflict, graphics should reflect pulling, opposition, collision, fission, imbalance, oppression, battlefield feel.
   - If the theme has fusion, graphics should reflect convergence, echo, flow, interlocking, resonance, connection, balance.
   - If the theme has predicament or game-theoretic feel, graphics should reflect branches, choices, nodes, equilibrium, paths, tension, cycles.
   - If the theme has history or epic feel, graphics may reference objects, motifs, ritual, and power expressed abstractly — while keeping a modern black-and-white experimental design style.
3. Abstract graphics should look like "concepts visualized", not random patterns.

[Texture & Finish]
1. Texture leans toward graphic design and high-end print visuals — black and white clean, edges sharp.
2. Subtle paper texture, faint noise, or print feel can be added — don't over-distress.
3. The result should be usable as: exhibition posters, opinion covers, design feature covers, conceptual visual posters, culture-and-thought covers.
4. Avoid photoreal humans, real-scene photography, cartoon illustration, colorful commercial ads, or childlike graphic language.

[Final Output]
Deliver a fully composed poster with a striking headline, strong abstract graphics, refined typography, unified black-and-white tone, and a serial / collectible quality.
Ensure the theme text is rendered accurately and the overall style is unified, with strong characteristics of "optical abstraction + conceptual typography + modern design poster".
