# Prompt Line Editorial

Create complete 16:9 Japanese slide images in the Prompt Line Editorial style. Turn business lessons into finished slide boards whose cards, arrows, labels, and diagrams stay readable as thumbnails while keeping this family's distinct look.

Generate each slide as one finished PNG with image_gen: background, Japanese text, diagrams, objects, icons, texture, and layout together. Do not rebuild the design with PPTX shapes, HTML/CSS, SVG, or local text overlays.

If this skill arrives as a ZIP, extract it first and read this file plus all required references. Do not infer the style from the ZIP name or cover alone.

## Required Reading

Read these before generating:

1. references/input-workflow.md
2. references/visual-system.md
3. references/slide-recipes.md
4. references/quality-bar.md

Inspect assets/reference-slides/style-reference.png, samples/contact_sheet.png, and all ten sample slides. Treat the ten samples as authoritative finished examples. Preserve the whole family's warm cream paper with hairline charcoal editorial margin rules and tick marks; uniform single-weight charcoal line-art illustration with white interiors; deep cobalt navy as the only heavy color mass; soft blush-rose flat circles and organic shapes behind the line art; fine halftone dot fields and 45-degree hatch fills; very large tight Japanese gothic navy headline with no outline and no shadow; subline on a hairline rule flanked by small navy parallelograms and dotted ellipses; open panels bounded by hairline rules with generous white space; solid navy label tabs with hatched corners; chunky solid navy arrows; hairline bottom strip with a diamond node and a navy underlined key phrase. Do not copy only the cover layout.

## Non-Negotiable Workflow

1. Parse numbered user text into an ordered slide plan.
2. Preserve meaning while compressing long copy into one headline, one subline, exactly three short labels, and one bottom takeaway.
3. Choose one role from references/slide-recipes.md.
4. Generate exactly one complete 16:9 Japanese slide image at a time with image_gen.
5. Save as slide_01.png, slide_02.png, and so on.
6. Compare each result with the bundled contact sheet and quality bar.
7. Regenerate unreadable Japanese, invented details, logo-like marks, weak hierarchy, or generic template output.
8. If PPTX or PDF is requested, make PNG slide art first and place each PNG full-bleed into the delivery file.

## Design DNA

Style: Line Editorial — a quiet Japanese magazine spread drawn almost entirely in single-weight line art. Design DNA: warm cream paper background with a faint tooth, framed by hairline charcoal rules that form an editorial margin box with small tick marks and a short diagonal-hatch bar at the top center; all illustration is uniform thin charcoal outline drawing with no fills — people at desks with laptops and mugs, pendant lamps hanging from the top edge, potted plants, bookshelves, window frames, clipboards, file boxes, pie and bar charts, speech bubbles, lightbulbs and magnifiers — each drawn with calm, confident, evenly weighted strokes and left mostly white inside; the only color mass is deep cobalt navy used for the headline, the arrow blocks, the label tabs and thin rules, plus soft blush-rose flat circles and organic shapes tucked behind the line art as the single warm accent, and small fields of fine halftone dots and 45-degree hatch fills for texture; the headline is very large tight Japanese gothic in deep cobalt navy with the first word set in a heavier weight, no outline and no shadow, sitting directly on the paper so the letterforms feel printed; below it the subline sits on a thin hairline rule flanked by two small solid navy parallelograms and tiny dotted ellipses at both ends; the main body is one dominant diagram of three open panels bounded by hairline rules with generous white space, each headed by a solid navy label tab whose left corner is filled with diagonal hatching, holding wide-tracked white lettering; solid navy chunky arrows step between panels; the bottom band is a full-width hairline-ruled strip with a small diamond node on its lower edge, holding charcoal text with the key phrase in cobalt navy underlined by a short navy rule, and a small line-art figure walking against a city skyline at the left with a rising sun and hills at the right; overall calm, literate, spacious, printed-magazine restraint; line-art vector illustration, no photo, no realistic people.

Make every metaphor functional with one continuous drawn line: blockers become knots where the line snags; change becomes a dense hatched column opening into two airy lanes across the gutter; steps become magazine columns joined by solid navy arrows; improvement becomes the line drawn as a circle threading three vignettes; checks become a ruled editorial list with outline boxes; roadmaps become the line curving from skyline to hills past milestone dots; priority becomes a hairline 2x2 with one blush-rose filled quadrant; daily use becomes vignettes hanging from a timeline rule; recap becomes one open panel of stacked note strips. Do not reduce the family to three equal cards with the right colors.

## Prompt Contract

Use this structure for every image:

Create exactly one complete 16:9 Japanese slide image.
Style: Prompt Line Editorial.
Design DNA: warm cream paper with hairline charcoal margin rules; all illustration in uniform single-weight charcoal outline with white interiors; deep cobalt navy as the only heavy color mass; soft blush-rose shapes and halftone dot and hatch fields as texture; very large tight Japanese gothic navy headline printed flat with no outline or shadow; subline on a hairline rule flanked by small navy parallelograms; one dominant diagram of open hairline panels with generous white space; exactly three solid navy label tabs with diagonal-hatched corners; chunky solid navy arrows; full-width hairline bottom strip with a diamond node and the key phrase in navy
Required Japanese text:
- Headline: [short headline]
- Subline: [short subline]
- Labels: [exactly 3 short labels]
- Bottom takeaway: [one concise sentence]
Slide role: [cover / problem / before-after / three-step / loop / checklist / roadmap / matrix / case / recap]
Composition: follow the matching recipe and inspect samples/contact_sheet.png. Use one dominant role-specific metaphor from references/slide-recipes.md instead of a generic card grid.
Generate background, text, diagrams, objects, texture, and layout together.
Avoid extra microcopy, page numbers, fake logos, QR codes, URLs, dates, prices, watermarks, photorealistic people, equal card grids, and generic PowerPoint/Canva/Gamma output.

## Output Defaults

- One 16:9 PNG per slide, Japanese text only, thumbnail-readable.
- File names slide_01.png through slide_NN.png in content order.
- Keep the family look consistent across every slide in a deck.
