## Components

### Composition

Build pages as layered stencil sheets: a dominant specimen region, narrow annotation rail, and staggered paper cards with purposeful negative-space cuts.

### Density

Medium density with generous gutters; cluster details inside framed cutouts instead of spreading equal cards.

### Hierarchy

Use high-contrast serif headings for artifact names, compact sans body text for instructions, and mono labels for registration data.

### Signature Patterns

- CSS clip-path polygon corners that imply stencil-cut apertures
- offset ::before paper shadows registered 8px down and right
- hairline crop marks drawn with linear-gradients at panel corners
- indigo masked bands crossing behind ivory cards
- single vermilion seal chip anchoring primary actions

## 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-019e04f7-ea18-7061-97b3-5525572112f6/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.

# Katagami Minimal Repro shadcn/ui Components

Artifact: `component-recipes-v1`
Author: `katagami-ui-projection`
Language ID: `en-019e04f7-ea18-7061-97b3-5525572112f6`
Slug: `katagami-minimal-repro`

## Intent

A compact quality-review recovery language that turns the paper-cut precision of katagami stencil craft into a restrained interface system: layered ivory surfaces, indigo cut apertures, hairline registration marks, and sparse vermilion seals.

## 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:

{
  "accent": "#B8452E",
  "background": "#F7F0E3",
  "border": "#B7A98E",
  "error": "#9F2D24",
  "info": "#315F86",
  "muted": "#66706A",
  "primary": "#1F3A5F",
  "secondary": "#D9CBB2",
  "success": "#2F6B4F",
  "surface": "#FFF9EC",
  "text": "#1E2528",
  "warning": "#A46A1F"
}

Typography:

{
  "base_size": "16px",
  "body_font": "Inter",
  "google_fonts_url": "https://fonts.googleapis.com/css2?family=Cormorant+Garamond:wght@600;700&family=Inter:wght@400;500;700&family=IBM+Plex+Mono:wght@500&display=swap",
  "heading_font": "Cormorant Garamond",
  "letter_spacing": "-0.01em",
  "line_height": 1.55,
  "mono_font": "IBM Plex Mono",
  "scale_ratio": 1.25
}

## Visual character to preserve

- ivory canvas with offset stacked paper panels and subtle fibrous texture
- indigo stencil apertures expressed as masked blocks, not decorative illustrations
- thin registration ticks and crop marks aligned to an 8px grid
- small vermilion seal chips used as the only warm accent
- asymmetric editorial composition with one dominant specimen panel

## ShadSync visual profile

{
  "family": "paper-collage",
  "material": "paper",
  "contour": "default",
  "border": "solid",
  "underlay": true,
  "grain": true,
  "stickerBadges": false,
  "motion": "lift",
  "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/katagami-minimal-repro/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: Use ivory, indigo, muted fiber gray, and a very small vermilion accent.; Make stencil craft structural through cuts, crop marks, layered sheets, and registration labels.; Keep text contrast strong and body text at readable sizes.; Use asymmetry with one clear focal specimen.; Disable decorative animation when exporting thumbnails.
- Do not: Do not use neon gradients, glass panels, or generic startup dashboards.; Do not fill the page with floral stencil ornament.; Do not rely on texture for legibility.; Do not create rows of equal cards without a dominant composition.; Do not add extra accent colors beyond the seal red.

## 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 <= 640px, tablet 641px-980px, desktop >= 981px",
  "grid": "Desktop uses a 12-column grid with a 5-column hero specimen, 4-column content stack, and 3-column annotation rail; tablet collapses to two columns; mobile becomes a single paper stack.",
  "whitespace": "Preserve at least 24px gutters on desktop and 16px on mobile; use blank paper margins as part of the identity."
