# Product UI Showcase

Create complete 16:9 Japanese slide images in the Product UI Showcase 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 bright white ground with very pale blue-gray blobs, light-blue dot-matrix patches and four-point sparkle glints; huge navy Japanese gothic headlines with cobalt word emphasis; white rounded-pill subline banners with thin cobalt borders and blue dotted leader lines; one large deep-navy rounded device frame with a slim icon rail, cobalt check chips and a cobalt-to-mint progress bar; light UI content tiles with checkbox rows, gray placeholder lines, donut and bar charts and rising mint arrows; white rounded feature cards with soft shadows and circled outline numerals; solid rounded label pills in cobalt and mint; solid cobalt and mint block arrows; a wide dark-navy rounded bottom band with a flat target icon and mint-highlighted 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: Product UI Showcase — Japanese SaaS product-launch business slide. Design DNA: bright white ground faintly tinted with very pale blue-gray blob shapes, small light-blue dot-matrix patches and light four-point sparkle glints in the corners; the headline is huge heavy Japanese gothic set in near-black navy with several words in vivid cobalt blue, no outline, tight kerning; directly under it a white rounded-pill subline banner with a thin cobalt border, connected outward by short blue dotted leader lines with round end dots to the flanking feature cards; the body is ONE dominant product mockup: a large deep-navy rounded device frame containing a light UI canvas with a slim left icon rail (home, check, person, chart, folder, gear glyphs, the active one a filled cobalt rounded square), a top status row of cobalt check chips and small arrow separators, a two-tone cobalt-to-mint progress bar, and inside it three light content tiles — a task list of cobalt checkbox rows on gray placeholder lines, a soft illustration tile with a flat vector person at a laptop with a speech bubble and a lightbulb bubble, and a summary tile with a cobalt donut chart, a stacked bar chart and a rising mint arrow line, plus a labeled progress bar with a percentage; flanking the mockup on both sides are white rounded feature cards with very soft shadows, each opened by a circled outline numeral in cobalt or mint, holding a flat vector icon cluster, a solid rounded label pill, a hairline divider and a small check-marked caption; solid cobalt and mint block arrows point inward and outward from the mockup; the bottom is one wide dark-navy rounded band with a large flat target-and-arrow icon at the left, huge white text with mint-highlighted words and a small mint sparkle at the right; palette is white, deep navy, cobalt, mint, light gray only; clean, airy, product-marketing polish, generous white space, soft shadows, crisp vector illustration, no photo.

Make every metaphor a product surface: blockers become a stalled UI with unchecked steps and an error badge; change becomes a legacy gray screen replaced by a cobalt-to-mint two-pane product screen; steps become a three-stage status row with numbered feature cards; improvement becomes feature cards orbiting the frame on a closed arrow ring; checks become a settings-style checklist screen with toggles; roadmaps become a release-timeline rail of milestone cards; priority becomes a 2x2 comparison board with one cobalt winning tile; daily use becomes a three-pane usage-day strip inside one frame; recap becomes a central launch card floating over the dimmed product frame. 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: Product UI Showcase.
Design DNA: bright white ground with pale blue-gray blobs, dot-matrix patches and sparkle glints; huge navy Japanese gothic headline with cobalt emphasis words; white rounded-pill subline banner with a thin cobalt border and blue dotted leader lines; one dominant deep-navy device frame holding a light UI canvas with an icon rail, cobalt check chips, a cobalt-to-mint progress bar and content tiles; white rounded feature cards with soft shadows and circled outline numerals; exactly three solid rounded label pills in cobalt and mint; solid cobalt and mint block arrows; a wide dark-navy rounded bottom band with a flat target icon and mint-highlighted 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.
