# Bauhaus Geometry System

Create complete 16:9 Japanese slide images in the Bauhaus Geometry System 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 off-white paper ground on a strict rectilinear grid; cobalt and mustard quarter circles bleeding off the top corners; solid red and cobalt squares, thin black plus-sign crosshairs and square fields of evenly spaced black dots; enormous flat-black Japanese gothic headlines with a primary-red final phrase; a single thin black edge-to-edge rule terminated by small mustard and cobalt squares carrying the subline between a red square and a cobalt circle; one dominant construction diagram of hairline-framed bays with solid corner number squares; flat geometric vector illustration of circles, half-circles and rectangles with thick black outlines and flat primary fills; heavy solid black wedge arrows; full-width solid colour label bars; a thin-keylined off-white bottom band with a black square holding a red disc and mustard triangle and fine black stripe rules. 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: Bauhaus Geometry System — Japanese design-school business slide. Design DNA: warm off-white paper ground with a faint tooth, composed on a strict rectilinear grid and punctuated only by pure primary geometry — a large cobalt-blue quarter circle bleeding off the top-left corner, a mustard-yellow quarter circle bleeding off the top-right, solid red and blue squares, a thin black plus-sign crosshair, and square fields of evenly spaced black dots; the headline is enormous ultra-bold Japanese gothic in flat black with the final phrase in primary red, set hard against the left margin with no shadow and no outline; beneath it a single thin black rule runs edge to edge terminated by a small mustard square at one end and a cobalt square at the other, and the subline sits centred on that rule in solid black flanked by a red square at the left and a cobalt circle at the right; the body is ONE dominant construction diagram framed by thin black hairlines: three equal bays divided by vertical black rules, each bay opened by a solid square in red, cobalt or mustard carrying a knocked-out white numeral at its top-left corner, containing a flat geometric vector illustration built from circles, half-circles, rectangles and thick black outlines with flat primary fills and no shading, and closed by a full-width solid colour bar at the bay's bottom holding the label in heavy knocked-out white or flat black type; heavy solid black wedge arrows step between the bays; large flat colour shapes — a cobalt half-disc, a mustard right triangle, a red circle — sit behind and beside the bays as structural counterweights rather than decoration; the bottom is one wide off-white band bordered by a thin black keyline holding huge black text with a red emphasis phrase, with a black square containing a red disc and a mustard triangle at its left end and a set of fine black stripe rules at its right end; palette is off-white, black, primary red, mustard yellow and cobalt blue only; everything is flat, unshaded, hard-edged and constructed, no gradients, no photo.

Make every metaphor a geometric construction: blockers become heavy solid blocks wedged into a black axis line; change becomes an irregular stack facing two rhythmic bands across a thick vertical rule; steps become three hairline-framed bays with corner number squares; improvement becomes a black hairline circle cut into three arcs by wedge arrowheads around a crosshair centre; checks become stacked registers with oversized black checkboxes; roadmaps become a staircase of three flat terraces rising to a hairline summit circle; priority becomes a four-quadrant square with one flooded primary-red panel; daily use becomes a three-cell register built only from primary shapes; recap becomes a keylined rectangle of three stacked colour strips between a quarter circle and a triangle. 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: Bauhaus Geometry System.
Design DNA: warm off-white paper ground with cobalt and mustard quarter circles bleeding off the top corners and square black dot fields; enormous flat-black Japanese gothic headline with a primary-red final phrase; a thin black edge-to-edge rule with mustard and cobalt end squares carrying the subline between a red square and a cobalt circle; one dominant construction diagram of hairline-framed bays with solid red, cobalt and mustard corner number squares; flat geometric illustration built from circles, half-circles and rectangles with thick black outlines; heavy solid black wedge arrows; exactly three full-width solid colour label bars; a thin-keylined off-white bottom band with a black square holding a red disc and a mustard triangle
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.
