rules
Use a wide document column with a slim annotation rail; persimmon sits at terminal decisions, row markers, or authored stamps, never as page chrome.
Medium reading density with compact metadata; avoid equal KPI cards and keep tables ledger-like.
Lead with type weight, spacing, and hairlines; use color only after hierarchy is clear in black, ash, and paper.
layout
Mobile stacks rail after content; tablet keeps a compact two-column arrangement.
Quiet document density with ledger tables and marginal notes rather than cards.
Desktop uses a 12-column page with 720px document body and 280px annotation rail.
32px page gutters, 24px panel interiors, 40px between major sections.
guidance
- 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 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.

# 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. ## Tokens ### Borders - **Default**: 1px solid #DDD4C6 - **Focus**: 2px solid #243E63 - **Hairline**: 1px solid #E8DFD1 - **Stamp**: 1px solid #C65A2E ### Colors | Name | Value | |------|-------| | 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` | ### Motion - **Accent**: seal mark appears with short scale-in - **Duration**: 160ms - **Easing**: cubic-bezier(.2,.7,.2,1) - **Hover**: tiny lift with paper shadow ### Radii - **Badge**: 10px - **Control**: 8px - **Panel**: 14px - **Stamp**: 6px ### Shadows - **Focus**: 0 0 0 3px rgba(36,62,99,0.18) - **Raised**: 0 1px 2px rgba(30,29,26,0.07) ### Spacing - **Lg**: 24px - **Md**: 16px - **Section**: 48px - **Sm**: 8px - **Xl**: 32px - **Xs**: 4px ### Surfaces - **Callout**: pale persimmon only for ephemeral notes - **Page**: rice paper field - **Panel**: warm white flat paper - **Rail**: slightly darker fiber band ### 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 ## Rules ### Composition Use a wide document column with a slim annotation rail; persimmon sits at terminal decisions, row markers, or authored stamps, never as page chrome. ### Density Medium reading density with compact metadata; avoid equal KPI cards and keep tables ledger-like. ### Hierarchy Lead with type weight, spacing, and hairlines; use color only after hierarchy is clear in black, ash, and paper. ### Signature Patterns - Hanko commit button: one persimmon filled action per screen, squared-soft radius, compact label, and no competing warm CTA nearby. - Marginal seal badge: a small persimmon square or circle in the rail marks authorship, unread state, or remembered exception with a text label beside it. - Fiber ledger table: warm paper rows use ash metadata, indigo links, and a single persimmon left rule only for changed or exceptional rows. - Registration hairlines: panels align to subtle fiber rules and corner ticks, translating katagami precision into functional layout. ## Layout ### Breakpoints Mobile stacks rail after content; tablet keeps a compact two-column arrangement. ### Density Quiet document density with ledger tables and marginal notes rather than cards. ### Grid Desktop uses a 12-column page with 720px document body and 280px annotation rail. ### Whitespace 32px page gutters, 24px panel interiors, 40px between major sections. ## Guidance ### 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. ### 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.
## Colors
Use the YAML color tokens as the normative palette. The prose below names the roles agents should preserve when generating UI.
| Token | Value |
|-------|-------|
| 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
- **Headline-Lg**: Inter Tight, 1.953rem, weight 700, line-height 1.1.
- **Headline-Md**: Inter Tight, 1.563rem, weight 600, line-height 1.15.
- **Body-Md**: Inter, 16px, weight 400, line-height 1.5.
- **Label-Md**: IBM Plex Mono, 0.75rem, weight 600, line-height 1.
## Layout
### Spacing Tokens
- **Lg**: `24px`
- **Md**: `16px`
- **Section**: `48px`
- **Sm**: `8px`
- **Xl**: `32px`
- **Xs**: `4px`
### Breakpoints
Mobile stacks rail after content; tablet keeps a compact two-column arrangement.
### Density
Quiet document density with ledger tables and marginal notes rather than cards.
### Grid
Desktop uses a 12-column page with 720px document body and 280px annotation rail.
### Whitespace
32px page gutters, 24px panel interiors, 40px between major sections.
## Elevation & Depth
### Shadows
- **Focus**: 0 0 0 3px rgba(36,62,99,0.18)
- **Raised**: 0 1px 2px rgba(30,29,26,0.07)
## Shapes
### Rounded
- **Badge**: `10px`
- **Control**: `8px`
- **Panel**: `14px`
- **Stamp**: `6px`
### Surfaces
- **Callout**: pale persimmon only for ephemeral notes
- **Page**: rice paper field
- **Panel**: warm white flat paper
- **Rail**: slightly darker fiber band
### Borders
- **Default**: 1px solid #DDD4C6
- **Focus**: 2px solid #243E63
- **Hairline**: 1px solid #E8DFD1
- **Stamp**: 1px solid #C65A2E
## Components
### Composition
Use a wide document column with a slim annotation rail; persimmon sits at terminal decisions, row markers, or authored stamps, never as page chrome.
### Density
Medium reading density with compact metadata; avoid equal KPI cards and keep tables ledger-like.
### Hierarchy
Lead with type weight, spacing, and hairlines; use color only after hierarchy is clear in black, ash, and paper.
### Signature Patterns
- Hanko commit button: one persimmon filled action per screen, squared-soft radius, compact label, and no competing warm CTA nearby.
- Marginal seal badge: a small persimmon square or circle in the rail marks authorship, unread state, or remembered exception with a text label beside it.
- Fiber ledger table: warm paper rows use ash metadata, indigo links, and a single persimmon left rule only for changed or exceptional rows.
- Registration hairlines: panels align to subtle fiber rules and corner ticks, translating katagami precision into functional layout.
## 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`.

}
## 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",

"motion": "lift",

]
}
## 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.
```tsx
import { Badge } from "@/components/ui/badge";
import { Button } from "@/components/ui/button";
import {
Card,
CardContent,
CardDescription,
CardFooter,
CardHeader,
CardTitle,
} from "@/components/ui/card";
import { Input } from "@/components/ui/input";
import { Tabs, TabsList, TabsTrigger } from "@/components/ui/tabs";
export function PersimmonSealOnWarmPaperShadcnKit() {
return (
<section className="grid gap-4 rounded-[var(--radius)] border bg-background p-4 text-foreground">
<div className="flex items-start justify-between gap-4">

<h2 className="mt-3 text-2xl font-semibold tracking-tight">Persimmon Seal on Warm Paper</h2>
<p className="mt-1 max-w-xl text-sm text-muted-foreground">
Use the Katagami registry theme, then compose these shadcn primitives
with the language-specific component recipes.
