# Children Workbook Practice

Create complete 16:9 Japanese slide images in the Children Workbook Practice 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 faint blue graph grid and red margin rule; spiral wire binding at the left edge and wooden desk edge behind; colored pencils lying on the page; crayon-textured hand-drawn Japanese gothic headline in sky blue, pencil black and correction red with white keyline; green pencil underline with yellow flick marks; wobbly hand-drawn box borders in blue colored pencil; circled numbers ①②③; filled crayon label bars in blue, green and yellow; red teacher marks — checks, 花丸 double circles, stars, hearts, flowers; soft pencil-and-watercolor illustrations; blue dashed-border bottom box with red emphasis words. 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: Children Workbook Practice — a Japanese elementary-school practice worksheet turned into a business slide. Design DNA: the whole slide is one spiral-bound workbook page lying on a warm wooden desk edge, warm cream paper with a faint pale-blue graph grid, a red vertical margin rule near the left, visible paper fiber and a soft page curl; a silver wire spiral binding runs down the left edge and real colored pencils lie across the bottom-left corner; the headline is enormous hand-drawn Japanese gothic with a crayon/colored-pencil texture inside the strokes and a soft chalky edge, split in three colors (deep sky blue for the first word, pencil-black for the middle, correction red for the emphasized word), each glyph carrying a thin white keyline and a soft paper shadow; a hand-drawn green pencil underline sweeps under the title with little yellow flick marks; the subline sits in a narrow rounded box with a wobbly hand-drawn blue border; the body is one dominant diagram made of hand-drawn rounded rectangles ruled in blue colored pencil, each with a small circled number ①②③ in the top-left corner and its illustration drawn in soft pencil-and-watercolor style with visible crayon shading; exactly three label plates sit on the bottom edge of the boxes as filled blue, green and yellow crayon bars with a tiny white icon and wide-tracked black lettering; teacher-style red pen marks are scattered as decoration — a big red check, a red double 花丸 circle, small stars, hearts, flowers, a smiling picture-book doodle, a lightbulb and a tiny cloud; the bottom band is a full-width rounded box with a blue dashed border holding pencil-black text with the key phrase in correction red; overall warm, gentle, hand-made, low-pressure and encouraging, like a kind teacher's marked-up drill sheet; hand-drawn vector illustration, no photo, no realistic people.

Make every metaphor functional with worksheet props: blockers become blank unanswered boxes with red correction crosses; change becomes a scribbled draft sheet flowing by a crayon arrow into a cleanly filled sheet with a gold star; steps become numbered drill boxes joined by pencil arrows; improvement becomes worksheet cards threaded on one spiral binding ring; checks become a ruled practice panel with red pen check rows; roadmaps become a dotted pencil trail past star-seal milestones ending in a 花丸; priority becomes a freehand pencil 2x2 with one cell circled in red; daily use becomes a three-box diary log strip; recap becomes one big red 花丸 holding three torn 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: Children Workbook Practice.
Design DNA: one spiral-bound workbook page on warm cream graph paper with red margin rule and wooden desk edge; huge crayon-textured hand-drawn Japanese gothic headline split into sky blue, pencil black and correction red with thin white keyline; green pencil underline; narrow subline box with wobbly blue hand-drawn border; one dominant diagram of blue-pencil-ruled rounded boxes with circled numbers ①②③ and soft pencil-watercolor illustrations; exactly three filled crayon label bars in blue, green and yellow; red teacher marks, star seals and doodles as decoration; full-width bottom box with blue dashed border and correction-red emphasis words
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.
