# Prompt Isometric City

Create complete 16:9 Japanese slide images in the Prompt Isometric City 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 continuous 30-degree isometric cityscape in matte 3D; pale gray-white towers with pale-sky glass, teal and coral roofed blocks, asphalt roads with white lane markings, round trees, canal, drones and light aircraft; glowing cyan holographic AI hub cube on light rings; enormous heavy Japanese gothic headline in teal, near-black and coral with thick white keyline and hard offset shadow; dark navy notched pill subline ribbon; thick beveled isometric slab cards standing on the city; matte 3D miniature props; three chunky 3D label plates in teal, cobalt and coral with circular white icon badges; wide dark-navy isometric bottom slab with rocket badge and yellow emphasis. 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: Isometric City — a Japanese business slide built on a bird's-eye isometric miniature city. Design DNA: the entire canvas is one continuous 30-degree isometric cityscape rendered in soft matte 3D with gentle ambient shadows: pale gray-white office towers with pale-sky glass grids, low teal and coral roofed blocks, wide asphalt roads with crisp white lane markings and crosswalks, roundabouts, rows of tidy round trees, small parks and a blue canal cutting through the lower corner, plus tiny drones and a light aircraft in the upper sky against a pale-blue sky with soft white clouds; at the visual center sits a glowing cyan holographic AI hub — a translucent cube with a circuit-brain glyph, floating on stacked light rings above a plaza with a beam of light; the headline is enormous heavy Japanese gothic sitting above the city like a signage lockup, split into deep teal for the first word, near-black for the middle kana and vivid coral-red for the emphasized word, every glyph wrapped in a thick white keyline and a hard offset drop shadow so it reads over the buildings; directly under it a dark navy pill-shaped ribbon banner with softly notched ends holds the white subline; the main body is one dominant diagram made of thick isometric slab cards that stand on the city like raised plazas or billboards, each slab beveled with a visible side thickness and its own drop shadow, holding matte 3D miniature props (clipboards, file boxes, pie and bar charts, laptops, lightbulbs, speech bubbles, magnifiers, potted plants); exactly three chunky 3D label plates in teal, cobalt blue and coral red are mounted on the front edge of the slabs with a circular white icon badge and wide-tracked white lettering; the bottom band is a wide dark-navy isometric slab spanning the city with a circular rocket badge at the left, white text and the key phrase in bright yellow, with a small flag on a plinth beside it; overall clean, corporate, spatial and toy-like; matte 3D vector rendering, no photo, no realistic people.

Make every metaphor functional with city infrastructure: blockers become jammed junctions with barriers and cones; change becomes a cramped old district linked by a highway ramp to two clean new avenues; steps become terraced plaza slabs with 3D numeral blocks; improvement becomes an elevated ring road circling the AI hub; checks become rooftop helipad check tiles; roadmaps become one avenue past flag plinths to a beacon tower; priority becomes a 2x2 super-grid of city blocks with one redeveloped district; daily use becomes a street of three building fronts by time of day; recap becomes a launch plaza with a rocket pad and mission pylons. 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 Isometric City.
Design DNA: one continuous 30-degree isometric city in matte 3D with pale towers, teal and coral blocks, lane-marked roads, trees and a canal under a pale-blue sky; a glowing cyan holographic AI hub at the center; enormous Japanese gothic headline in teal, near-black and coral with thick white keyline and hard offset shadow; dark navy notched pill subline ribbon; one dominant diagram of thick beveled isometric slab cards holding matte 3D miniature props; exactly three chunky 3D label plates in teal, cobalt and coral with circular white icon badges; wide dark-navy isometric bottom slab with a circular rocket badge and bright-yellow 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.
