# Persimmon Seal on Warm Paper

## Philosophy

A quiet neutral product language with persimmon used like a hanko seal: decisive, small, human, and rare. The interface remains paper-like and text-first while the accent marks authorship, commitment, and remembered exceptions.

### Values

- warm paper restraint
- persimmon as rare confirmation mark
- text-first product clarity
- craft precision without skeuomorphism
- small signals over colorful chrome

### Anti-Values

- orange marketing energy
- multiple competing accent buttons
- sepia-heavy beige surfaces
- ink-splat skeuomorphism
- dashboard tile walls

### Visual Character

- Warm rice-paper and white surfaces carry the viewport, with sumi text, ash metadata, and fiber-colored hairlines defining structure through quiet contrast and generous margins.
- Persimmon appears as a compact seal: one primary commit button, a notification dot, a row marker, or an authored stamp no larger than a small badge.
- Indigo stays reserved for links, navigation, and focus so the persimmon signal never has to compete with another warm call-to-action.
- Panels use flat paper layers, square-to-soft corners, and hairline registration marks rather than heavy shadows, gradients, or glossy effects.

- Pair seal marks with concise labels and timestamps.
- Use indigo for focus and navigation.

### Don't

- Do not make orange the background or navigation color.
- Do not scatter multiple persimmon buttons through one screen.
- Do not use ink splatter, glossy stamps, or decorative Japanese motifs.
- Do not rely on accent color alone for alerts.

### Accessibility

Persimmon states require text, position, or icon reinforcement; focus is indigo and high contrast.

### Usage Context

Best for editorial tools, approval flows, writing systems, review queues, and products where a rare commit mark should feel human.

# Persimmon Seal on Warm Paper

## Overview

A quiet neutral product language with persimmon used like a hanko seal: decisive, small, human, and rare. The interface remains paper-like and text-first while the accent marks authorship, commitment, and remembered exceptions.

### Values

- warm paper restraint
- persimmon as rare confirmation mark
- text-first product clarity
- craft precision without skeuomorphism
- small signals over colorful chrome

### Anti-Values

- orange marketing energy
- multiple competing accent buttons
- sepia-heavy beige surfaces
- ink-splat skeuomorphism
- dashboard tile walls

### Visual Character

- Warm rice-paper and white surfaces carry the viewport, with sumi text, ash metadata, and fiber-colored hairlines defining structure through quiet contrast and generous margins.
- Persimmon appears as a compact seal: one primary commit button, a notification dot, a row marker, or an authored stamp no larger than a small badge.
- Indigo stays reserved for links, navigation, and focus so the persimmon signal never has to compete with another warm call-to-action.
- Panels use flat paper layers, square-to-soft corners, and hairline registration marks rather than heavy shadows, gradients, or glossy effects.

## 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-019ee037-f140-72d2-a461-e7cb5b22112e/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 Begin with paper, sumi text, and fiber hairlines before adding persimmon.
- Do Use exactly one persimmon commit action per view.
- Do Pair seal marks with concise labels and timestamps.
- Do Use indigo for focus and navigation.
- Don't Do not make orange the background or navigation color.
- Don't Do not scatter multiple persimmon buttons through one screen.
- Don't Do not use ink splatter, glossy stamps, or decorative Japanese motifs.
- Don't Do not rely on accent color alone for alerts.

### Accessibility

Persimmon states require text, position, or icon reinforcement; focus is indigo and high contrast.

### Usage Context

Best for editorial tools, approval flows, writing systems, review queues, and products where a rare commit mark should feel human.

# Persimmon Seal on Warm Paper shadcn/ui Components

Artifact: `component-recipes-v1`
Author: `katagami-ui-projection`
Language ID: `en-019ee037-f140-72d2-a461-e7cb5b22112e`
Slug: `persimmon-seal-warm-paper`

## Intent

A quiet neutral product language with persimmon used like a hanko seal: decisive, small, human, and rare. The interface remains paper-like and text-first while the accent marks authorship, commitment, and remembered exceptions.

## 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": "#F1D6C5",
  "background": "#F8F4EC",
  "border": "#DDD4C6",
  "danger": "#A94825",
  "foreground": "#1E1D1A",
  "muted": "#777167",
  "primary": "#C65A2E",
  "primary_deep": "#A94825",
  "secondary": "#243E63",
  "success": "#5F7442",
  "surface": "#FFFCF6",
  "surface_muted": "#F1E9DC",
  "warning": "#9A6A2E"
}

Typography:

{
  "body_font": "Inter",
  "body_line_height": "1.6",
  "body_size": "16px",
  "font_mono": "IBM Plex Mono, SFMono-Regular, ui-monospace, monospace",
  "font_sans": "Inter, ui-sans-serif, system-ui, sans-serif",
  "google_fonts_url": "https://fonts.googleapis.com/css2?family=IBM+Plex+Mono:wght@400;500;600&family=Inter:wght@400;500;600;700&family=Inter+Tight:wght@500;600;700&display=swap",
  "heading_font": "Inter Tight",
  "label_tracking": "0.02em",
  "mono_font": "IBM Plex Mono"
}

## Visual character to preserve

- Warm rice-paper and white surfaces carry the viewport, with sumi text, ash metadata, and fiber-colored hairlines defining structure through quiet contrast and generous margins.
- Persimmon appears as a compact seal: one primary commit button, a notification dot, a row marker, or an authored stamp no larger than a small badge.
- Indigo stays reserved for links, navigation, and focus so the persimmon signal never has to compete with another warm call-to-action.
- Panels use flat paper layers, square-to-soft corners, and hairline registration marks rather than heavy shadows, gradients, or glossy effects.

## ShadSync visual profile

{
  "family": "paper-collage",
  "material": "paper",
  "contour": "default",
  "border": "solid",
  "underlay": false,
  "grain": true,
  "stickerBadges": true,
  "motion": "lift",
  "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: Begin with paper, sumi text, and fiber hairlines before adding persimmon.; Use exactly one persimmon commit action per view.; Pair seal marks with concise labels and timestamps.; Use indigo for focus and navigation.
- Do not: Do not make orange the background or navigation color.; Do not scatter multiple persimmon buttons through one screen.; Do not use ink splatter, glossy stamps, or decorative Japanese motifs.; Do not rely on accent color alone for alerts.

## Copy-paste component example

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