# Nail Art Color Chart

Create complete 16:9 Japanese slide images in the **Nail Art Color Chart** style. Convert rough numbered content such as `1枚目には...`, `2枚目には...` into finished slides.

Generate each slide as one complete PNG with `image_gen`: marble background, Japanese text, diagrams, nail objects, people or hands, glitter, 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. Read this file and the required references; do not infer the style from the ZIP name alone.

## Real Generated Sample Rule

Treat `samples/slide_01.png` through `samples/slide_10.png` as authoritative finished examples, not placeholders. Preserve their marble canvas, pastel color system, gold trim, giant Japanese typography, stitched plaques, nail-tip swatches, color charts, polish objects, crystal accents, edge density, and polished salon-proposal finish.

Use the cover as the main anchor. Use slides 02-10 to learn how the same design DNA behaves across problem, comparison, process, loop, checklist, roadmap, matrix, case, and recap roles.

## Required Reading

Before generating slides, read:

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 samples. Match the complete visual family, not merely its pastel palette.

## Non-Negotiable Workflow

1. Parse numbered slide text in the supplied order.
2. Preserve the meaning. Compress long copy to one headline, one subline, exactly three short labels, and one bottom takeaway.
3. Assign one role from `references/slide-recipes.md`.
4. Choose one central nail-tip, color-chart, consultation, polish, design-card, magnifier, or reusable-swatch metaphor that explains the idea.
5. Generate exactly one complete 16:9 Japanese slide image at a time with `image_gen`.
6. Use the cover plus the closest role sample as visual references.
7. Save images sequentially as `slide_01.png`, `slide_02.png`, and so on.
8. Compare every result with the bundled samples and `references/quality-bar.md`.
9. Regenerate or precisely edit any slide with unreadable Japanese, extra pseudo-text, writing on design cards or bottles, fake booking details, weak hierarchy, or generic template styling.
10. If PPTX or PDF is requested, generate PNG slides first, then place each PNG edge-to-edge on a 16:9 page.

## Design DNA

- Soft white marble canvas with faint translucent shadows, gold foil arcs, pearls, crystals, and jewel-like sparkle accents.
- Cherry pink for action and emotional emphasis, lavender for experimentation and analysis, milky blue for completion and calm results, with restrained rose gold and pearl.
- Oversized bold Japanese display headline using black, cherry-pink, or pink-to-lavender faces, thick white cutout shadow, and thin gold keyline.
- Cherry-pink gradient subline plaque with double-gold trim, three large stitched rounded label plaques, and a wide white jewel-edged bottom takeaway plaque with a faceted heart gem.
- Glossy nail-tip fans, pastel color charts, reusable clear swatch cases, blank consultation and design cards, blank polish bottles, fine brushes, magnifiers, pearls, gems, and gold foil.
- Use a refined nail artist, client hand, or manicure hand only when the lesson benefits from a human role; keep the visual system dominant.
- One central nail-design or color-consultation metaphor rather than an equal generic card grid.
- Cute but premium salon-proposal energy with rich detail and large readable Japanese copy.

## Prompt Contract

Use this structure for every generation:

```text
Create exactly one complete 16:9 Japanese slide image.
Style: Nail Art Color Chart.
Design DNA: soft-white marble, cherry pink, lavender, milky blue, fine gold glitter and trim, pearls, crystals, giant Japanese paper-cut display type, cherry-pink double-gold subline plaque, stitched pastel labels, jewel-edged takeaway plaque, nail-tip swatches, color charts, blank design cards, clear cases, blank polish bottles, fine brush, magnifier, and sparkle accents.
Required Japanese text:
- Headline: [one short headline]
- Subline: [one 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 in references/slide-recipes.md and visually match samples/contact_sheet.png.
Generate background, text, objects, diagrams, effects, and layout together as one finished image.
Render only the required text. Keep design cards, booking cards, swatch cases, polish bottles, palettes, and review bubbles blank. Avoid logos, QR codes, URLs, dates, prices, brand names, watermarks, unrelated English, pseudo-text, and generic Gamma/Canva/PowerPoint output.
```

## Output Defaults

- Output PNG slide images.
- Use 16:9 landscape.
- Name files sequentially.
- Split or summarize content that would force small text. Never place paragraphs on the image.
