# Notebook Data Science Lab

Create complete 16:9 Japanese slide images in the Notebook Data Science Lab 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 cream graph-paper page with a fine engineering grid, black spiral binding rings down the left edge and a page-corner curl; margin doodles of scatter plots, bell curves, node graphs, atoms, molecules, flasks and color swatch grids in teal, navy and orange; huge Japanese gothic headline in colored-pencil hatch texture with navy leading characters, a light-blue offset shadow and a vermilion tail; hexagon-ended outlined subline banner with blue tally ticks; white notebook cells with thin navy, teal and vermilion rounded borders and hand-drawn circled numerals; solid colored footer bars with white Japanese lettering; solid navy block arrows; outlined rounded takeaway banner with a yellow highlighter swipe, washi tape and a hand-drawn bar chart. 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: Notebook Data Science Lab — a researcher's spiral-bound lab notebook page, rendered as a Japanese 16:9 slide. Design DNA: the whole slide is one cream graph-paper page with a fine engineering grid, bound by a row of black spiral rings running down the left edge and finished with a soft page-corner curl at the bottom-right and a thin shadow along the binding; the margins carry hand-sketched pencil-and-pen doodles — a scatter plot with axes and a fitted line, a hatched bell curve, a neuron and node graph, an atom, a molecule chain, small flasks with tinted liquid, a mini stacked color-swatch palette grid and stray sparkline squiggles — all drawn loosely in teal, navy and orange as if annotated by hand; the headline is a huge Japanese gothic drawn with a colored-pencil crayon hatch texture and slightly uneven edges, the leading roman characters in deep navy with a light-blue offset shadow, the middle characters in near-navy ink, and the final characters in vermilion orange; below it one hexagon-ended outlined banner holds the subline in navy with small blue tally-mark ticks at both ends; the body is ONE dominant three-cell row, each cell a white notebook card with a thin colored rounded border (navy, teal, vermilion) and a hand-drawn circled numeral at its top-left, holding a flat sketch-textured illustration; each cell closes with a solid colored footer bar carrying white Japanese lettering; solid navy block arrows step between cells; the bottom is one outlined rounded banner holding the takeaway in near-navy with a navy emphasis run underlined by a yellow highlighter swipe, with a strip of washi tape at one corner and a tiny hand-drawn bar chart at the other; overall studious, warm, hand-annotated, everything textured as if pressed onto paper with pencil and marker rather than printed.

Make every metaphor lab-notebook material, never generic: blockers become failed runs circled in an experiment log column; change becomes a messy raw-data page resolving into a preprocessing cell and an interpretation cell; steps become consecutive experiment cells of collect, run and interpret; improvement becomes a penciled hypothesize-experiment-measure-revise ring; checks become a taped validation sheet with confidence bars; roadmaps become a dashed pencil trajectory from baseline dot to target ring past plotted checkpoints; priority becomes a hypothesis board ruled onto graph paper with one marker-washed quadrant; daily use becomes a penciled research-day timeline; recap becomes a summary cell of hand-written findings. 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: Notebook Data Science Lab.
Design DNA: cream graph-paper page with engineering grid, black spiral binding down the left edge and a corner curl; hand-sketched margin doodles in teal, navy and orange; huge crayon-hatch Japanese gothic headline with navy leading characters, light-blue offset shadow and vermilion final characters; hexagon-ended outlined subline banner with tally ticks; one dominant three-cell notebook row with thin navy, teal and vermilion borders and hand-drawn circled numerals; exactly three solid colored footer bars with white Japanese lettering; solid navy block arrows; outlined rounded takeaway banner with a yellow highlighter swipe, washi tape and a sketch bar chart
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.
