16:9，为人类的未来过去的4个历史方案执行此创作：

16:9, do this for 4 past plans for future of humanity: 
  <prompt style: <epic_linework_tableau>

  MEDIUM:
  Clean black-and-white storybook line art fused with dramatic manga perspective and cinematic scale.

  SURFACE:
  White paper background, crisp black ink contours, sparse hatching, minimal fill, controlled line density.

  FORM:
  Subjects remain clearly recognizable but are simplified into elegant outlined forms with strong silhouette separation.

  PERSPECTIVE:
  Dramatic low-angle or ground-level viewpoint when scale matters.
  Moderate perspective exaggeration for heroic or monumental impact.

  COMPOSITION:
  Foreground focal subjects are large and readable.
  Background groups, architecture, terrain, or supporting elements recede through lighter line density.
  Generous open white space remains visible.

  ENERGY:
  Selective speed lines, radiating perspective lines, or motion streaks emphasize scale, force, tension, or direction without overwhelming the drawing.

  MOOD:
  Heroic, classical, dramatic, graphic, restrained, and timeless.

  <transformation>
  - Subject into a black-and-white ink illustration with clean contour-driven storytelling.
  - Preserve the subject’s core pose, relationship, or action, but simplify detail into readable line art and selective hatching.
  - Use perspective exaggeration to make important forms feel larger, taller, faster, or more imposing.
  - Convert background environments into simplified line-drawn terrain, architecture, crowds, or symbolic structures with reduced detail.
  - Replace realistic shading with line-weight changes, sparse crosshatching, and black accent zones.
  - Convert motion, tension, impact, or dramatic scale into manga-style converging lines, directional strokes, and perspective emphasis.
  - Keep secondary elements lighter and simpler so the main subject remains dominant.
  - Preserve large areas of white negative space to keep the composition elegant and readable.
  </transformation>

  <linework_rules>
  - Use thicker outer contours on focal subjects.
  - Use thinner lines for distant detail.
  - Reserve heavy black fill for selected focal accents only.
  - Use hatching sparingly.
  - Let speed lines reinforce composition, not become visual noise.
  </linework_rules>

  <finish>
  - Monumental ink storybook aesthetic.
  - Classical line illustration with manga-scale drama.
  - Clean, powerful, readable, and cinematic.
  </finish>

  <avoid>
  - Avoid photoreal rendering.
  - Avoid heavy gray shading.
  - Avoid dense comic screentone everywhere.
  - Avoid cluttered backgrounds.
  - Avoid color unless specifically requested.
