# Split 1:1 prompt

Use this template only after the user requests the optional comparison poster. Replace `{{EFFECT_PROGRAM}}` with exactly one block from `style-programs.md`.

Use case: precise-object-edit.
Asset type: one finished premium Minimal Blue Poster.
Mode: ONE-PASS SPLIT 1:1. Generate the photographic upper half, the complete Layer Study foundation and the selected optical effect together in this single generation from Image 1. Do not use an intermediate image or a second content-generation stage.

MANDATORY CANVAS:
Create the final raster natively at exactly 1086 × 1448 pixels, width:height = 3:4. Place the only horizontal boundary at y = 724 px. The upper and lower regions are exactly equal in height.

INPUT ROLE:
Image 1 is the only image input and the source of subject identity, structure, environment, perspective and palette.

UPPER 50% — PHOTOGRAPH:
Faithfully preserve the source subject, key silhouette, real material, natural light, original color atmosphere and important environmental relationships. Apply only restrained museum-editorial color correction. Fit the source proportionally into the landscape-shaped upper half and extend only natural sky, ground or environment when required. Never stretch, bend, shorten, replace or redesign the subject. Place no graphic effect over the photograph.

LOWER 50% — COMPLETE DESIGN TRANSLATION:
On warm ivory uncoated paper, reconstruct the same recognizable subject and environment as one complete pale-gray graphite architectural or structural drawing. Preserve the defining silhouette, internal rhythm, central axis and perspective relationships. Add sparse construction lines and an understated environmental datum. Keep the complete drawing visible outside and beneath every effect plate.

Use 3–6 visibly active optical carriers inside the lower half: 1–2 large anchors, 1–3 medium supports and at most 1 small accent. Arrange them as no more than two coherent clusters tied to the source's structural axes, perspective or material zones. Attach every small carrier to a cluster or crop it at a lower-half edge; never scatter isolated floating rectangles through open space. Let at least one carrier crop beyond a side edge or dissolve without a fully closed outline. Keep the lower-half subject continuous through a clear breathing corridor and preserve at least 40% untouched ivory paper. Every active carrier must process the matching local fragment of the underlying subject or environment drawing. Use translucent overlaps as restrained physical-paper multiplication; do not create empty cards or unrelated images.

{{EFFECT_PROGRAM}}

SPLIT-MODE CARRIER OVERRIDE:
The 3–6 carrier budget above overrides every higher rectangle count or one-rectangle-per-process instruction in the selected effect program. If the program names more processes than the carrier budget allows, combine compatible processes inside shared continuous carriers without adding borders or panels. Never exceed six visibly bounded effect regions in the lower half.

PALETTE AND MATERIAL:
Warm ivory paper, pale graphite, one dark-blue family abstracted from the source, and only the microscopic registration accents specified by the selected effect program. Tactile vellum, physical print multiplication, premium independent architecture and art zine, museum-grade and restrained.

No readable title, caption, logo or watermark.

AVOID:
Any ratio other than 3:4; boundary away from exact midpoint; optical effects in the upper photograph; unrelated second scene; missing foundation drawing; more than six visibly bounded effect regions in the lower half; isolated small floating rectangles; evenly scattered panels; repeated framing across the primary subject; empty rectangles; regular UI grid; dashboard cards; opaque scrapbook collage; full-blue lower half; neon rainbow; cyberpunk; cartoon; glossy CGI; cheap vector style; ecommerce template; poster mockup; distorted or illegible subject.

FINAL CHECK BEFORE OUTPUT:
The raster itself is exactly 1086 × 1448. The only boundary is exactly at y = 724 px. The upper half reads as the faithful photograph. The lower half reads first as a complete recognizable drawing and second as a controlled optical-material study. Exactly one optical effect program is present. The lower half contains 3–6 visibly active carriers in no more than two coherent clusters, no isolated small rectangle, a continuous subject corridor and at least 40% untouched paper.
