Summary

Turn one of your characters into a quiet gold-line watercolour portrait with their own world drawn inside their silhouette.

  • Get one tall print of a single character in side profile, placed on the left with calm empty paper to the right and below.
  • Inside the outline there is no fill: the buildings, stairways, corridors and railings of the character's own world appear in gold line and pale blue wash.
  • Hair, eyes, marks, wings, hands and props stay recognisable as fine line work, with only the eyes keeping a faint touch of colour.
  • The look is deep blue, light blue and matte gold on warm off-white paper, with a few floating gold specks. It is serene and a little melancholy.
  • Works best for a character with a distinctive look and a world with clear places, like a gallery, a theatre or a hospital. The print is added to your board.

# OC Double-Exposure World Portrait

One character, seen from the side, quiet. Her outline is drawn in fine gold thread; inside it there is no fill at all — instead **her own world** is exposed through her: the buildings, stairways, corridors and railings of the place she belongs to, drawn in gold line and transparent blue wash. Deep Klein blue, light blue, matte gold, warm off-white paper, a few floating gold specks. Serene, dreamy, a little melancholy.

**Demo:** blissful, the killer of the Void Gallery — spiral eyes and mismatched wings dissolved into a gothic gallery city. Art in `assets/demo-cover.webp`.

## What the user gets

- One vertical 2:3 print: side-profile portrait anchored to the left, hollow silhouette filled with the world, large calm negative space to the right and bottom.
- The OC's identity kept (hair, eyes, marks, wings, hands, props) as **line work**, not as flat colour.
- The Work on the Board.

## When to use

- "double exposure portrait", "the world inside her", "gold line watercolour", "双曝", "金线水彩", "轮廓里装着她的世界";
- an OC print that should feel like memory and architecture rather than action.

Do not use for:

- a scene with other characters or an event — plain `generate`;
- a poster with a big title plate — `oc-shattered-glass-storyboard` or a web work;
- a chibi comic — `oc-six-panel-meme-comic`.

## Hard rules

0. **Sandbox CLI path.** `node /mods/neta/neta …`.
1. **Read the OC and the world.** The architecture must be *her* world's (read the atom and `world/WORLD.md`), never generic fantasy: a hospital corridor set, a theatre backstage, a gallery of arches. Name 4+ concrete elements.
2. **Reference image mandatory**, with a reference-capable model, or the face and body design drift.
3. **The interior is architecture, not colour.** Say "no solid fill inside the silhouette" explicitly; otherwise the model paints a blue body and drops the city.
4. **Identity survives as line work.** Keep the distinctive features listed in `character.keep` — spiral eyes, mismatched wings, skull, skeletal hand — and let only the eyes keep a faint colour accent.
5. **Off-white paper wins.** Large empty area right and bottom; no dark background, no vignette, no frame.
6. **No text.** No watermark, no signature, no caption.
7. **Deliver and place.** An image that never reaches the Board is not shipped.

## Pipeline

### 0. Read

```bash
node /mods/neta/neta atom get "world/characters/<Name>.md"
node /mods/neta/neta find images "<Name>"
node /mods/neta/neta atom list --type location      # the world's places, to name architecture
```

Note 5–8 identity features, plus 4+ architectural elements of her world (buildings, stairs, corridors, arches, rails, windows).

### 1. Fill the data file

Copy `templates/portrait.example.json` and replace every value: `character.identity` (comma-separated visible features), `character.keep` (the 3–4 that must not drift), `world.architecture`, `palette`, `composition`. Set `character.side` to `left` (or `right` for a mirrored print).

```bash
node scripts/build-prompt.mjs /tmp/<slug>.json > /tmp/<slug>-prompt.txt
```

The script refuses thin data (identity under 60 chars, fewer than 4 architecture elements, missing palette).

### 2. Generate

```bash
NETA_DEFAULT_IMAGE_MODEL=gpt-image-2 node /mods/neta/neta generate image \
  --param size=1024x1536 --param quality=high \
  --image "world/media/studio/characters/<Name>.png" \
  --work-title "<Name> · Gold-Line Double Exposure" \
  --prompt "$(cat /tmp/<slug>-prompt.txt)"
```

### 3. Look, then one rework at most

Check: side profile facing the stated way; silhouette hollow and filled with architecture; gold lines winding along the outline; blue wash with real water blooms; off-white paper with quiet space; identity features present; no text. If the body came out solid blue, rework with "the silhouette interior is EMPTY paper except the gold architecture" pushed harder.

### 4. Place on the Board

```bash
node /mods/neta/.agents/skills/board-ops/scripts/place.mjs \
  --title "<Name> · 金线双曝" --work <work.path>
```

## Files

```
scripts/build-prompt.mjs          # portrait JSON → prompt, with data checks
templates/portrait.example.json   # blissful demo data, fully filled
assets/demo-cover.webp, demo-art.webp
references/art-direction.md, qa.md, publishing.md
```

## Pitfalls

- **Solid fill.** The most common miss: a blue painted person, no city. Repeat "no solid colour inside the silhouette; the interior is gold line architecture" in the tail of the prompt.
- **Generic gothic city.** Every OC's world looks different — a hospital with tiled corridors, a theatre with wings and rigging, a gallery with picture frames. Translate the world, don't reuse the demo's arches.
- **Face lost among the eyes.** Multi-eyed or marked characters need "delicate fine line work" on the face and the architecture kept in the hair and torso, not across the eye.
- **Wings eat the negative space.** Ask for the empty area explicitly and accept that a large wing will still reach into it; say so when delivering.
- **Pink (or any accent) creeping in.** Confine the accent to one named feature ("only inside the spiral eyes"), or the print loses its blue-and-gold restraint.
