- Art direction: Cyanotype study. Source logic: Engineering sheets and cyanotype contact prints. Graphic purpose: A constructed form with projection lines; every line describes the same geometry.
- No arbitrary mirrored copies, arbitrary rotations or unrelated motif mixing.
- Algorithm: random-design/2; rule fingerprint: 71caaea0f85d569c
- Reproduction: preserve this design JSON and use the matching release. Seed alone does not encode history-dependent candidate selection.
- 字体: IBM Plex Mono / IBM Plex Sans; CJK: Noto Sans SC. Scale 1.278; tracking -0.012em; leading 1.572.
- 构图: frame; 6 columns; margins 6.085%; graphic on right; balance 0.601; rhythm alternating.
- 图形: guilloche; count 4; stroke 1.887; amplitude 0.394; rotation 0°. Use the exported SVG or reproduce its parameters.
- Surface: fine-lines; radius 0px; depth flat.
- WCAG text/paper contrast: body 7:1; secondary 4.63:1; accent text 4.62:1. Use accentInk for text on paper, onAccent for text on accent. Accent2 is decorative, not a general text colour.
