summary
Katagami Cut Paper Systems translates the craft of Japanese stencil-cutting into a precise interface language: fibrous washi fields, dark persimmon-resist edges, repeating cut apertures, and careful registration marks create software that feels handmade, disciplined, and quietly ceremonial rather than decorative or nostalgic.
values
Make every surface feel cut, layered, or registered by hand, with interface structure emerging from negative space rather than from generic cards.Use restraint as evidence of craft: a warm paper ground, soot ink, one persimmon-brown accent, and small indigo measuring marks.Treat repetition as a production method, not ornament; motifs should align with navigation, grouping, filtering, or proofing tasks.Let small imperfections humanize the system while preserving crisp layout hierarchy and accessible interaction states.Favor tool-room specificity: pattern ledgers, dye batches, stencil proofs, drying schedules, and archive drawers instead of analytics dashboards.Make the signature recognizable in monochrome through cutout edges, bridges, registration pins, and layered stencil shadows.
anti-values
×No generic SaaS cards, CRM metrics, marketing hero blobs, or evenly weighted feature grids.×No neon Japan pastiche, anime character art, torii clichés, cherry-blossom wallpaper, or ornamental patterns detached from function.×No glossy gradients, glassmorphism, synthetic triadic palettes, or soft app-store roundness.×No fake distressed texture that harms legibility; paper grain must stay quiet and structural.

rules
composition
Build a craft archive scene, not a dashboard. Use one dominant stencil proof table, a narrow registration rail, one dense swatch ledger, and a wide interrupted proof strip. Panels should be rectangular, asymmetrical, and visibly layered; avoid three equal cards or repeated same-size modules.
density
Alternate calm washi margins with concentrated production notations. The viewer should feel a workshop bench: one spacious proofing surface, then tight measurements, pin holes, and swatch metadata clustered by task.
hierarchy
Largest area is the current stencil proof with oversize serif title and cut aperture silhouette.Secondary hierarchy comes from persimmon rule weight, proof numbers, and indigo registration marks.Dense ledgers use compact mono labels and 4-8px group gaps while major sheets separate by 64-112px.Interactive controls read as paper tabs, pinned labels, and square cut buttons; hover lifts the whole sheet by a few pixels.Use empty paper margins as a premium material, not as unfilled space.
signature patterns
CSS clip-path aperture panels carve stepped notches and bridge tabs from rectangular sheets, creating a stencil-cut silhouette without decorative images.Registration marks are built from pseudo-elements: indigo crosshair pins, small numbered circles, and crop ticks positioned at panel corners.Proof strips use repeating-linear-gradient and mask-like square voids to create a textile stencil repeat with one interrupted cell for compositional asymmetry.Layer shadows are dry offset blocks, never blur-heavy glows, so depth resembles stacked paper and survives monochrome conversion.Navigation tabs are flat paper slips threaded through cut slots, with active states shown by alignment pins rather than color floods.
layout
breakpoints

mobile <= 680px, tablet 681-1024px, desktop >= 1025px; tablet becomes 6 columns, mobile one column with horizontal proof strips retained.

density
Desktop is medium-high density with one large quiet proof field balanced by tight archive controls; mobile keeps content readable by stacking rail, proof, ledger, and strip.
grid
Desktop uses a 12-column max-width 1240px grid with 24px gutters; hero proof spans 7 columns, registration rail spans 3, ledger spans 2, and proof strip crosses 10 columns with an offset start.
responsive
Remove nonessential corner ticks before shrinking text; preserve the stencil silhouette and registration rail order so the signature remains visible at every viewport.
whitespace

Major sections use 64-112px separation; related labels and measurements use 4-12px spacing, satisfying a strong grouping ratio.

guidance
do
  • Name screens as specific stencil workshop artifacts: proof table, dye batch ledger, bridge repair queue, registration rail, archive drawer.
  • Use warm washi neutrals, soot ink, persimmon brown, and sparse indigo measurement marks.
  • Let negative space and cut apertures create the visual identity before adding texture.
  • Vary panel scale dramatically with one dominant proof and one dense ledger.
  • Show functional repetitions such as pattern swatches, proof numbers, and dye batch states.
  • Keep body text at 15-16px with strong contrast and visible focus outlines.
  • Use square or flat-edged controls; if a pill is needed, keep accent bars separate from the rounded shape.
avoid
  • Do not use cherry blossoms, fans, temple icons, anime characters, or generic Japanese souvenir motifs.
  • Do not create equal feature cards, analytics widgets, CRM pipelines, or abstract productivity dashboards.
  • Do not add gradients, glass panels, neon colors, or pastel rainbow accents.
  • Do not mix arbitrary border radii; the language is primarily square and cut.
  • Do not make paper grain noisy enough to reduce contrast or create screenshot artifacts.
  • Do not rely on color alone for proof status; pair every mark with text or geometry.
  • Do not use one-sided accent borders on rounded elements.

# Katagami Cut Paper Systems

## Philosophy

Katagami Cut Paper Systems translates the craft of Japanese stencil-cutting into a precise interface language: fibrous washi fields, dark persimmon-resist edges, repeating cut apertures, and careful registration marks create software that feels handmade, disciplined, and quietly ceremonial rather than decorative or nostalgic.

### Values

- Make every surface feel cut, layered, or registered by hand, with interface structure emerging from negative space rather than from generic cards.
- Use restraint as evidence of craft: a warm paper ground, soot ink, one persimmon-brown accent, and small indigo measuring marks.
- Treat repetition as a production method, not ornament; motifs should align with navigation, grouping, filtering, or proofing tasks.
- Let small imperfections humanize the system while preserving crisp layout hierarchy and accessible interaction states.
- Favor tool-room specificity: pattern ledgers, dye batches, stencil proofs, drying schedules, and archive drawers instead of analytics dashboards.
- Make the signature recognizable in monochrome through cutout edges, bridges, registration pins, and layered stencil shadows.

### Anti-Values

- No generic SaaS cards, CRM metrics, marketing hero blobs, or evenly weighted feature grids.
- No neon Japan pastiche, anime character art, torii clichés, cherry-blossom wallpaper, or ornamental patterns detached from function.
- No glossy gradients, glassmorphism, synthetic triadic palettes, or soft app-store roundness.
- No fake distressed texture that harms legibility; paper grain must stay quiet and structural.

### Visual Character

- Stencil aperture frames: flat-edged panels with irregular inset cutouts, tiny bridge tabs, and visible negative-space slots that define hierarchy even without color.
- Registration anatomy: small indigo crosshairs, numbered proof pins, crop ticks, and misprint offsets placed around controls as functional alignment cues.
- Washi and kakishibu materiality: warm fibrous paper surfaces, soot-ink type, persimmon-brown rule work, and dry offset shadows instead of glossy depth.
- Pattern-repeat logic: repeated cells appear as production swatches, archive drawers, or proof strips with one deliberately interrupted motif to break the grid.

## Rules

### Composition

Build a craft archive scene, not a dashboard. Use one dominant stencil proof table, a narrow registration rail, one dense swatch ledger, and a wide interrupted proof strip. Panels should be rectangular, asymmetrical, and visibly layered; avoid three equal cards or repeated same-size modules.

### Density

Alternate calm washi margins with concentrated production notations. The viewer should feel a workshop bench: one spacious proofing surface, then tight measurements, pin holes, and swatch metadata clustered by task.

### Hierarchy

- Largest area is the current stencil proof with oversize serif title and cut aperture silhouette.
- Secondary hierarchy comes from persimmon rule weight, proof numbers, and indigo registration marks.
- Dense ledgers use compact mono labels and 4-8px group gaps while major sheets separate by 64-112px.
- Interactive controls read as paper tabs, pinned labels, and square cut buttons; hover lifts the whole sheet by a few pixels.
- Use empty paper margins as a premium material, not as unfilled space.

### Signature Patterns

- CSS clip-path aperture panels carve stepped notches and bridge tabs from rectangular sheets, creating a stencil-cut silhouette without decorative images.
- Registration marks are built from pseudo-elements: indigo crosshair pins, small numbered circles, and crop ticks positioned at panel corners.
- Proof strips use repeating-linear-gradient and mask-like square voids to create a textile stencil repeat with one interrupted cell for compositional asymmetry.
- Layer shadows are dry offset blocks, never blur-heavy glows, so depth resembles stacked paper and survives monochrome conversion.
- Navigation tabs are flat paper slips threaded through cut slots, with active states shown by alignment pins rather than color floods.

## Layout

### Breakpoints

mobile <= 680px, tablet 681-1024px, desktop >= 1025px; tablet becomes 6 columns, mobile one column with horizontal proof strips retained.

### Density

Desktop is medium-high density with one large quiet proof field balanced by tight archive controls; mobile keeps content readable by stacking rail, proof, ledger, and strip.

### Grid

Desktop uses a 12-column max-width 1240px grid with 24px gutters; hero proof spans 7 columns, registration rail spans 3, ledger spans 2, and proof strip crosses 10 columns with an offset start.

### Responsive

Remove nonessential corner ticks before shrinking text; preserve the stencil silhouette and registration rail order so the signature remains visible at every viewport.

### Whitespace

Major sections use 64-112px separation; related labels and measurements use 4-12px spacing, satisfying a strong grouping ratio.

## Guidance

### Do

- Name screens as specific stencil workshop artifacts: proof table, dye batch ledger, bridge repair queue, registration rail, archive drawer.
- Use warm washi neutrals, soot ink, persimmon brown, and sparse indigo measurement marks.
- Let negative space and cut apertures create the visual identity before adding texture.
- Vary panel scale dramatically with one dominant proof and one dense ledger.
- Show functional repetitions such as pattern swatches, proof numbers, and dye batch states.
- Keep body text at 15-16px with strong contrast and visible focus outlines.
- Use square or flat-edged controls; if a pill is needed, keep accent bars separate from the rounded shape.

### Don't

- Do not use cherry blossoms, fans, temple icons, anime characters, or generic Japanese souvenir motifs.
- Do not create equal feature cards, analytics widgets, CRM pipelines, or abstract productivity dashboards.
- Do not add gradients, glass panels, neon colors, or pastel rainbow accents.
- Do not mix arbitrary border radii; the language is primarily square and cut.
- Do not make paper grain noisy enough to reduce contrast or create screenshot artifacts.
- Do not rely on color alone for proof status; pair every mark with text or geometry.
- Do not use one-sided accent borders on rounded elements.

### Accessibility

Maintain WCAG AA contrast on all text, preserve visible keyboard focus as a double soot/indigo outline, keep annotations supplementary, and ensure the stencil apertures never remove essential hit areas or labels.

### Usage Context

Ideal for craft archives, pattern libraries, museum collection tools, textile production systems, print proofing apps, and quiet editorial products that need ritual, precision, and material intelligence.

# Katagami Cut Paper Systems

## Overview

Katagami Cut Paper Systems translates the craft of Japanese stencil-cutting into a precise interface language: fibrous washi fields, dark persimmon-resist edges, repeating cut apertures, and careful registration marks create software that feels handmade, disciplined, and quietly ceremonial rather than decorative or nostalgic.

### Values

- Make every surface feel cut, layered, or registered by hand, with interface structure emerging from negative space rather than from generic cards.
- Use restraint as evidence of craft: a warm paper ground, soot ink, one persimmon-brown accent, and small indigo measuring marks.
- Treat repetition as a production method, not ornament; motifs should align with navigation, grouping, filtering, or proofing tasks.
- Let small imperfections humanize the system while preserving crisp layout hierarchy and accessible interaction states.
- Favor tool-room specificity: pattern ledgers, dye batches, stencil proofs, drying schedules, and archive drawers instead of analytics dashboards.
- Make the signature recognizable in monochrome through cutout edges, bridges, registration pins, and layered stencil shadows.

### Anti-Values

- No generic SaaS cards, CRM metrics, marketing hero blobs, or evenly weighted feature grids.
- No neon Japan pastiche, anime character art, torii clichés, cherry-blossom wallpaper, or ornamental patterns detached from function.
- No glossy gradients, glassmorphism, synthetic triadic palettes, or soft app-store roundness.
- No fake distressed texture that harms legibility; paper grain must stay quiet and structural.

### Visual Character

- Stencil aperture frames: flat-edged panels with irregular inset cutouts, tiny bridge tabs, and visible negative-space slots that define hierarchy even without color.
- Registration anatomy: small indigo crosshairs, numbered proof pins, crop ticks, and misprint offsets placed around controls as functional alignment cues.
- Washi and kakishibu materiality: warm fibrous paper surfaces, soot-ink type, persimmon-brown rule work, and dry offset shadows instead of glossy depth.
- Pattern-repeat logic: repeated cells appear as production swatches, archive drawers, or proof strips with one deliberately interrupted motif to break the grid.

## shadcn/ui Usage

When the target app uses shadcn/ui, copy DESIGN.md with shadcn instead of the plain DESIGN.md. It contains the same Katagami design-language source plus the shadcn/ui primitives, imports, theme variables, component recipes, and preview-shot guidance.

DESIGN.md with shadcn: `/language/en-019e04f8-acd0-7242-9ee0-1ec7f9f09fb3/DESIGN.with-shadcn.md`.

The shadcn page also exposes optional machine-readable files for automation, but the human-facing handoff is DESIGN.md with shadcn.

Install recommended primitives with `npx shadcn@latest add button card input textarea select dialog sheet tabs badge separator checkbox switch slider tooltip dropdown-menu table`.

Use these primitives in shadcn apps:
- button
- card
- input
- textarea
- select
- dialog
- sheet
- tabs
- badge
- separator
- checkbox
- switch
- slider
- tooltip
- dropdown-menu
- table

Implementation rule for agents: import shadcn primitives from `@/components/ui/*`, apply the generated CSS variables first, then compose the language-specific recipes from the companion MD. Katagami remains the source of truth; shadcn names are the implementation surface.

Maintain WCAG AA contrast on all text, preserve visible keyboard focus as a double soot/indigo outline, keep annotations supplementary, and ensure the stencil apertures never remove essential hit areas or labels.

### Usage Context

Ideal for craft archives, pattern libraries, museum collection tools, textile production systems, print proofing apps, and quiet editorial products that need ritual, precision, and material intelligence.

# Katagami Cut Paper Systems shadcn/ui Components

Artifact: `component-recipes-v1`
Author: `katagami-ui-projection`
Language ID: `en-019e04f8-acd0-7242-9ee0-1ec7f9f09fb3`
Slug: `katagami-cut-paper-systems`

## Intent

Katagami Cut Paper Systems translates the craft of Japanese stencil-cutting into a precise interface language: fibrous washi fields, dark persimmon-resist edges, repeating cut apertures, and careful registration marks create software that feels handmade, disciplined, and quietly ceremonial rather than decorative or nostalgic.

## Required primitives

- button
- card
- input
- textarea
- select
- dialog
- sheet
- tabs
- badge
- separator
- checkbox
- switch
- slider
- tooltip
- dropdown-menu
- table

Install with `npx shadcn@latest add button card input textarea select dialog sheet tabs badge separator checkbox switch slider tooltip dropdown-menu table`.

## Token cues

  "display_line_height": 1.14,

  "mono_font": "Spline Sans Mono",
  "scale_ratio": 1.24
}

## Visual character to preserve

- Stencil aperture frames: flat-edged panels with irregular inset cutouts, tiny bridge tabs, and visible negative-space slots that define hierarchy even without color.
- Registration anatomy: small indigo crosshairs, numbered proof pins, crop ticks, and misprint offsets placed around controls as functional alignment cues.
- Washi and kakishibu materiality: warm fibrous paper surfaces, soot-ink type, persimmon-brown rule work, and dry offset shadows instead of glossy depth.
- Pattern-repeat logic: repeated cells appear as production swatches, archive drawers, or proof strips with one deliberately interrupted motif to break the grid.

## ShadSync visual profile

## Signature component recipes

### Button
Use `Button` for primary, secondary, outline, and ghost actions. Primary actions must expose the language's strongest contrast pair, while secondary and ghost actions should preserve the surface treatment instead of falling back to default neutral SaaS styling.

### Card
Use `Card`, `CardHeader`, `CardContent`, `CardFooter`, and `CardAction` as the main composition frame. Cards should demonstrate the language's surface, border, hierarchy, and density rules rather than appearing as generic rounded rectangles.

### Input and Textarea
Use `Input` and `Textarea` with visible focus rings, field labels, validation states, and the language's rhythm. Forms should show real product content, not placeholder-only controls.

### Select, Tabs, and Table
Use `Select`, `Tabs`, and `Table` to prove navigation, filtering, and dense data states. The table should show row rhythm, separators, hover/focus states, and an empty or status state when the language calls for it.

### Dialog and Sheet
Use `Dialog` for centered decisions and `Sheet` for contextual editing. Both should inherit the language's spacing, border, overlay, and motion rules.

## Preview shots

- `application-shell`: dashboard or workspace shell with navigation, cards, forms, and state badges.
- `detail-editor`: focused editing flow using input, textarea, select, switch/checkbox, dialog or sheet, and action buttons.
- `data-operations`: table-heavy operational view with tabs, dropdown menu affordances, badges, and destructive/empty states.
- Each preview shot must include a renderable `scene` payload with concrete headline, description, actions, and rows/fields/stats for the UI preview.

## Implementation contract

- Start from local `ui/src/components/ui` shadcn-style primitives; do not create a second component system.
- Apply `/katagami/shadcn/katagami-cut-paper-systems/registry-theme.json` variables, then use these recipes for composition and state design.
- Preserve Katagami token names as source metadata; shadcn semantic names are only the export surface.
- Do: Name screens as specific stencil workshop artifacts: proof table, dye batch ledger, bridge repair queue, registration rail, archive drawer.; Use warm washi neutrals, soot ink, persimmon brown, and sparse indigo measurement marks.; Let negative space and cut apertures create the visual identity before adding texture.; Vary panel scale dramatically with one dominant proof and one dense ledger.; Show functional repetitions such as pattern swatches, proof numbers, and dye batch states.; Keep body text at 15-16px with strong contrast and visible focus outlines.; Use square or flat-edged controls; if a pill is needed, keep accent bars separate from the rounded shape.
- Do not: Do not use cherry blossoms, fans, temple icons, anime characters, or generic Japanese souvenir motifs.; Do not create equal feature cards, analytics widgets, CRM pipelines, or abstract productivity dashboards.; Do not add gradients, glass panels, neon colors, or pastel rainbow accents.; Do not mix arbitrary border radii; the language is primarily square and cut.; Do not make paper grain noisy enough to reduce contrast or create screenshot artifacts.; Do not rely on color alone for proof status; pair every mark with text or geometry.; Do not use one-sided accent borders on rounded elements.

## Copy-paste component example

This generated starter proves the import shape. Production Katagami agents should replace it with a language-specific product composition.

## Layout notes

{
  "breakpoints": "mobile <= 680px, tablet 681-1024px, desktop >= 1025px; tablet becomes 6 columns, mobile one column with horizontal proof strips retained.",
  "density": "Desktop is medium-high density with one large quiet proof field balanced by tight archive controls; mobile keeps content readable by stacking rail, proof, ledger, and strip.",
  "grid": "Desktop uses a 12-column max-width 1240px grid with 24px gutters; hero proof spans 7 columns, registration rail spans 3, ledger spans 2, and proof strip crosses 10 columns with an offset start.",
  "responsive": "Remove nonessential corner ticks before shrinking text; preserve the stencil silhouette and registration rail order so the signature remains visible at every viewport.",
  "whitespace": "Major sections use 64-112px separation; related labels and measurements use 4-12px spacing, satisfying a strong grouping ratio."
