# Persimmon Seal on Warm Paper

## Philosophy

A restrained text-first product language where warm paper, indigo ink, hairline stencil structure, and rare persimmon seal marks make commitment and authorship feel deliberate rather than loud.

### Values

- quiet authorship
- text-first clarity
- craft restraint
- precise marginal context
- rare decisive accent

### Anti-Values

- orange marketing energy
- generic dashboard chrome
- confetti badges
- heavy sepia nostalgia
- decorative ink splats

### Visual Character

- Use a warm rice-paper page background with subtle linear fiber texture and matte off-white panels instead of glossy white cards.
- Compose screens as a broad reading column with a slim marginal rail separated by vertical hairlines and registration ticks.
- Render persimmon only as compact seal geometry: square stamps, tiny dots, row markers, and one terminal filled action per view.
- Use indigo and sumi typography with medium-weight marginal captions, short rules, and restrained uppercase metadata spacing.
- Favor square-to-small-radius surfaces, single-pixel stencil borders, and tiny cut-corner notches over soft SaaS rounding.

- rare decisive accent

### Anti-Values

- orange marketing energy
- generic dashboard chrome
- confetti badges
- heavy sepia nostalgia

### Visual Character

- Use a warm rice-paper page background with subtle linear fiber texture and matte off-white panels instead of glossy white cards.
- Compose screens as a broad reading column with a slim marginal rail separated by vertical hairlines and registration ticks.
- Render persimmon only as compact seal geometry: square stamps, tiny dots, row markers, and one terminal filled action per view.

## Components

### Composition

Use editorial document flow: a wide primary text/work column, a narrow right marginal rail, and horizontal rule groups that feel like registration guides.

### Density

Moderate, readable density for long text with tables kept calm and scannable through hairlines rather than filled bands.

### Hierarchy

Lead with dark sumi headings and indigo section labels; metadata sits in compact marginal captions; persimmon appears only at decisive commit or authored-state moments.

### Signature Patterns

- Persimmon hanko marks: compact square seals, notification dots, and one filled commit button, never broad orange chrome.
- Washi marginalia rail: a right-side context column with captions, counters, and annotations divided by fiber hairlines.
- Stencil registration ticks: tiny corner ticks and double rules that align cards, tables, and section headers.
- Flagged table rows use a three-pixel persimmon left marker and changed value stamp instead of whole-row color fills.

## 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-019ee039-44c1-7891-b2ba-b9e169462af7/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.

# Persimmon Seal on Warm Paper shadcn/ui Components

Artifact: `component-recipes-v1`
Author: `katagami-ui-projection`
Language ID: `en-019ee039-44c1-7891-b2ba-b9e169462af7`
Slug: `persimmon-seal-warm-paper`

## Intent

A restrained text-first product language where warm paper, indigo ink, hairline stencil structure, and rare persimmon seal marks make commitment and authorship feel deliberate rather than loud.

## 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": "#C65A2E",
  "background": "#F8F4EC",
  "border": "#DDD4C6",
  "error": "#9F2D20",
  "info": "#37577F",
  "muted": "#777167",
  "primary": "#243E63",
  "secondary": "#777167",
  "success": "#4F6F45",
  "surface": "#FFFCF6",
  "text": "#1E1D1A",
  "warning": "#A94825"
}

Typography:

{
  "base_size": "16px",
  "body_font": "Noto Sans",
  "google_fonts_url": "https://fonts.googleapis.com/css2?family=IBM+Plex+Mono:wght@400;500;600&family=IBM+Plex+Sans:wght@400;500;600;700&family=Noto+Sans:wght@400;500;600;700&display=swap",
  "heading_font": "IBM Plex Sans",
  "letter_spacing": "-0.01em",
  "line_height": 1.55,
  "mono_font": "IBM Plex Mono",
  "scale_ratio": 1.22
}

## Visual character to preserve

- Use a warm rice-paper page background with subtle linear fiber texture and matte off-white panels instead of glossy white cards.
- Compose screens as a broad reading column with a slim marginal rail separated by vertical hairlines and registration ticks.
- Render persimmon only as compact seal geometry: square stamps, tiny dots, row markers, and one terminal filled action per view.
- Use indigo and sumi typography with medium-weight marginal captions, short rules, and restrained uppercase metadata spacing.
- Favor square-to-small-radius surfaces, single-pixel stencil borders, and tiny cut-corner notches over soft SaaS rounding.

## ShadSync visual profile

{
  "family": "paper-collage",
  "material": "paper",
  "contour": "default",
  "border": "solid",
  "underlay": false,
  "grain": true,
  "stickerBadges": true,
  "motion": "still",
  "density": "dense",
  "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/persimmon-seal-warm-paper/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 persimmon as a rare seal of action, authorship, or anomaly.; Keep most surfaces warm white or rice paper with indigo/sumi text hierarchy.; Show context as marginal notes and registration ticks rather than colorful widgets.; Use realistic text-heavy product scenes with a few data operations.
- Do not: Do not create multiple orange CTAs or orange navigation chrome.; Do not use heavy sepia paper textures, ink splats, or faux aged parchment.; Do not turn every badge into a pill or confetti accent.; Do not rely on generic dashboard cards without editorial document structure.

## Copy-paste component example

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