do
  • Start with a metaphorical ink image or fragment, then arrange copy and controls around its implied tension.
  • Use black rules, caption rails, and hatching before adding the oxblood accent.
  • Keep digital components visibly editorial: buttons can feel like stamped labels, cards like paper sheets, and charts like annotated proofs.
  • Let line weight communicate importance; the thickest strokes belong to focal metaphors and decisive actions.
avoid
  • Do not use bright decorative gradients, glassmorphism, or friendly rounded SaaS cards.
  • Do not scatter ink splatter randomly; every mark must point, divide, emphasize, or symbolize.
  • Do not introduce multiple accent hues or colorful fills that overpower the monochrome ink system.
  • Do not center every layout; asymmetry and cropped edges are required for editorial tension.

# Noir Paper Metaphor

## Philosophy

Noir Paper Metaphor translates editorial ink drawing into a disciplined digital fine-art interface: warm paper grounds, assertive black linework, cropped metaphorical imagery, and one restrained accent that behaves like an editor's mark rather than decoration.

### Values

- expressive line as structure
- visual metaphor before ornament
- warm paper tactility inside digital surfaces
- art-directed asymmetry with editorial restraint

### Anti-Values

- generic magazine grids with stock imagery
- decorative splatter that does not carry meaning
- full-spectrum color palettes
- default rounded SaaS components

### Visual Character

- Use off-white paper panels with subtle radial grain and uneven inset borders so each module reads like scanned editorial stock.
- Build compositions from heavy black rule systems, hand-drawn underline strokes, and vertical caption rails instead of neutral card chrome.
- Place monochrome ink figure fragments in masked oval and torn-rectangle frames with CSS hatching overlays to create metaphorical focal points.
- Reserve a single muted oxblood accent for annotations, issue markers, pull-quote glyphs, and critical interaction states only.

## 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-019dde36-5c30-7391-ae2e-e37d05b46d98/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.

## Do's and Don'ts

- Do Start with a metaphorical ink image or fragment, then arrange copy and controls around its implied tension.
- Do Use black rules, caption rails, and hatching before adding the oxblood accent.
- Do Keep digital components visibly editorial: buttons can feel like stamped labels, cards like paper sheets, and charts like annotated proofs.
- Do Let line weight communicate importance; the thickest strokes belong to focal metaphors and decisive actions.
- Don't Do not use bright decorative gradients, glassmorphism, or friendly rounded SaaS cards.
- Don't Do not scatter ink splatter randomly; every mark must point, divide, emphasize, or symbolize.
- Don't Do not introduce multiple accent hues or colorful fills that overpower the monochrome ink system.
- Don't Do not center every layout; asymmetry and cropped edges are required for editorial tension.

# Noir Paper Metaphor shadcn/ui Components

Artifact: `component-recipes-v1`
Author: `katagami-ui-projection`
Language ID: `en-019dde36-5c30-7391-ae2e-e37d05b46d98`
Slug: `noir-paper-metaphor`

## Intent

Noir Paper Metaphor translates editorial ink drawing into a disciplined digital fine-art interface: warm paper grounds, assertive black linework, cropped metaphorical imagery, and one restrained accent that behaves like an editor's mark rather than decoration.

## 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

Colors:

{
  "primary": "#11100E",
  "secondary": "#2B2925",
  "accent": "#9A2F24",
  "background": "#F3EBDD",
  "surface": "#FFF8EA",
  "text": "#16130F",
  "muted": "#756C5F",
  "border": "#211D18",
  "error": "#B43A2E",
  "success": "#54734E",
  "warning": "#B87920",
  "info": "#315E74"
}

Typography:

{
  "heading_font": "Cormorant Garamond",
  "body_font": "Source Serif 4",
  "mono_font": "IBM Plex Mono",
  "base_size": "16px",
  "scale_ratio": 1.27,
  "line_height": 1.52,
  "letter_spacing": "-0.015em",
  "google_fonts_url": "https://fonts.googleapis.com/css2?family=Cormorant+Garamond:wght@500;600;700&family=Source+Serif+4:opsz,wght@8..60,400;8..60,600;8..60,700&family=IBM+Plex+Mono:wght@400;500;600&display=swap"
}

## Visual character to preserve

- Use off-white paper panels with subtle radial grain and uneven inset borders so each module reads like scanned editorial stock.
- Build compositions from heavy black rule systems, hand-drawn underline strokes, and vertical caption rails instead of neutral card chrome.
- Place monochrome ink figure fragments in masked oval and torn-rectangle frames with CSS hatching overlays to create metaphorical focal points.
- Reserve a single muted oxblood accent for annotations, issue markers, pull-quote glyphs, and critical interaction states only.

## ShadSync visual profile

{
  "family": "paper-collage",
  "material": "paper",
  "contour": "default",
  "border": "dashed",
  "underlay": true,
  "grain": true,
  "stickerBadges": false,
  "motion": "lift-rotate",
  "density": "balanced",
  "accents": [
    "primary",
    "accent",
    "secondary",
    "muted"
  ]
}

## 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/noir-paper-metaphor/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: Start with a metaphorical ink image or fragment, then arrange copy and controls around its implied tension.; Use black rules, caption rails, and hatching before adding the oxblood accent.; Keep digital components visibly editorial: buttons can feel like stamped labels, cards like paper sheets, and charts like annotated proofs.; Let line weight communicate importance; the thickest strokes belong to focal metaphors and decisive actions.
- Do not: Do not use bright decorative gradients, glassmorphism, or friendly rounded SaaS cards.; Do not scatter ink splatter randomly; every mark must point, divide, emphasize, or symbolize.; Do not introduce multiple accent hues or colorful fills that overpower the monochrome ink system.; Do not center every layout; asymmetry and cropped edges are required for editorial tension.

## Copy-paste component example

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