Compose screens as a shoji lattice on a dark ground: a strict modular grid of cells, most resting in shadow, a few lit. Keep at least one large resting zone per viewport so density never goes uniform. An upright reading rail carries region names in the margin.
Hierarchy is carried by light: a lit cell warms from the top edge to signal it is live; Mincho display sits over gothic UI and mono metadata. Emphasis comes from glow and position, not from many weights or many colours. Exactly one vermilion ember marks the single thing that needs a person.
Low-to-medium. Cells are compact but never cramped; the lattice breathes with generous padding and dark resting cells between lit ones.
Three devices: (1) the shoji light-grid — a kumiko lattice whose cells glow warm amber when live and rest dark otherwise; (2) one tilted vermilion ember seal per board for the single reading that needs a person; (3) an upright reading rail naming regions in the margin. Surfaces have no frame border — structure is carried by light, the lattice hairline, and the trailing heading rule.
Desktop is a shoji lattice: a fixed narrow upright reading rail beside a modular grid of cells (4-up on wide). Tablet drops to 2-up and compresses the rail; phone collapses to a single column with the rail lying down to a horizontal label band.
Darkness is structural emptiness: 40-96px outer margins on desktop, 24-40px tablet, 16-24px phone. Never light every cell; leave resting cells dark to create rhythm.

sumi-ink-wash
Sumi-e ink-wash brushwork applied on a dark night field: one dark pigment, graded washes, decisive loaded strokes, and bare dark paper as structural negative space, with a single restrained vermilion seal mark. The inked subject (a glowing andon lantern) is pushed to one edge so the larger dark area carries the headline overlay.
Hero images push the inked, warm-lit subject to one edge and leave the larger area as bare dark negative space for the headline overlay. One small vermilion seal mark is the only saturated colour.

# Andon
## Overview
A night-and-paper interface language. The screen is a paper lantern grid on a deep sumi-indigo ground: every surface is a shoji cell, dark when resting and warm when it holds something live. It reads the same Japanese paper as its source but from the dark side — intentional emptiness becomes the dark ground itself, light becomes the message, and a single vermilion ember marks the one thing that needs a person.
### Values
- light as the only chrome
- darkness as structural emptiness (ma)
- one rationed ember
- paper-and-lantern tactility
- calm operational clarity
### Anti-Values
- defaulting to white or pale washes
- a second loud accent
- framing every surface with a border
- flooding the board with status chips
- bounce or overshoot motion
### Visual Character
- a strict shoji lattice of cells: resting cells sit dark, live cells warm from the top edge inward like washi lit from behind
- one vermilion ember seal pressed at a slight tilt marks the single reading that needs a person — one per board
- an upright reading rail names regions in the margin in mono, so the lattice itself stays wordless and lit
- a deep sumi-indigo night ground carries everything with a faint blue-grey kumiko grain crossing the field
- warm lantern amber is the whole live vocabulary; cool moon-indigo plays the quiet secondary

- **Sm**: `8px`
- **Md**: `16px`
- **Lg**: `24px`

### Grid
Desktop is a shoji lattice: a fixed narrow upright reading rail beside a modular grid of cells (4-up on wide). Tablet drops to 2-up and compresses the rail; phone collapses to a single column with the rail lying down to a horizontal label band.
### Whitespace
Darkness is structural emptiness: 40-96px outer margins on desktop, 24-40px tablet, 16-24px phone. Never light every cell; leave resting cells dark to create rhythm.
### Density
low-to-medium
### Responsive
390px single column with the rail as a horizontal band, scrollable/wrapping tables, full-width actions; 680px stacked panels; 880px two-up lattice; 1200px+ full four-up board; the full-bleed hero spans 100vw, contained content caps and centres on ultra-wide.
### Breakpoints
- **Xl**: 1200px
- **Lg**: 880px
- **Md**: 680px
- **Sm**: 390px
## Elevation & Depth
### Shadows
- **Sm**: 0 1px 0 rgba(0,0,0,0.2)
- **Md**: 0 14px 36px rgba(0,0,0,0.22)
- **Lg**: 0 18px 40px rgba(0,0,0,0.25)
- **Glow**: 0 0 0 1px rgba(242,200,121,0.42), 0 0 60px rgba(242,200,121,0.16)
## Shapes
### Rounded
- **None**: `0px`
- **Md**: `16px`
- **Lg**: `24px`
- **Full**: `9999px`
### Surfaces
- **Treatment**: lit-paper-cell
- **Card Style**: dark shoji cells with no frame border; live cells carry a warm amber top-down glow, resting cells stay dark
- **Bg Pattern**: faint blue-grey kumiko lattice grain on a sumi-night ground
### Borders
- **Default Width**: 1px
- **Style**: solid
- **Character**: kumiko hairlines used only as lattice dividers between cells and trailing heading rules — never as a frame drawn around a container
## Components
### Composition
Compose screens as a shoji lattice on a dark ground: a strict modular grid of cells, most resting in shadow, a few lit. Keep at least one large resting zone per viewport so density never goes uniform. An upright reading rail carries region names in the margin.
### Hierarchy
Hierarchy is carried by light: a lit cell warms from the top edge to signal it is live; Mincho display sits over gothic UI and mono metadata. Emphasis comes from glow and position, not from many weights or many colours. Exactly one vermilion ember marks the single thing that needs a person.
### Density
Low-to-medium. Cells are compact but never cramped; the lattice breathes with generous padding and dark resting cells between lit ones.
### Signature
Three devices: (1) the shoji light-grid — a kumiko lattice whose cells glow warm amber when live and rest dark otherwise; (2) one tilted vermilion ember seal per board for the single reading that needs a person; (3) an upright reading rail naming regions in the margin. Surfaces have no frame border — structure is carried by light, the lattice hairline, and the trailing heading rule.
## 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-019efd71-ffc5-7861-957f-c3ebcd858420/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 light only the cells that are true right now and let the rest rest in the dark
- Do use warm amber for live and reserve the vermilion ember for the one thing that needs a person
- Do carry structure with light, surface, and the trailing rule before any border
- Do keep region names in the upright reading rail so the lattice stays wordless
- Do tune neutrals cool to the sumi-night ground
- Don't do not default to white or wash the ground pale — the night is the point
- Don't do not add a second loud accent or flood the board with embers
- Don't do not frame every cell with a charcoal border or inset inner frame
- Don't do not centre everything or build perfectly symmetrical dashboards
- Don't do not animate with bounce, spring, or playful overshoot
### Accessibility
Body text 17px+ in warm paper ink on the sumi ground at high contrast. The ember seal is always paired with a text label so status never relies on colour alone. Focus rings swap to lantern amber. Motion respects prefers-reduced-motion; the settled state renders with no JavaScript.
## Imagery Direction
### Pairs With
sumi-ink-wash
### Summary
Sumi-e ink-wash brushwork applied on a dark night field: one dark pigment, graded washes, decisive loaded strokes, and bare dark paper as structural negative space, with a single restrained vermilion seal mark. The inked subject (a glowing andon lantern) is pushed to one edge so the larger dark area carries the headline overlay.
### Subjects
- a glowing paper-and-wood andon lantern in a night garden
- a single lit shoji screen seen from the dark
- a stone garden lantern under pine
- a tetsubin teapot by lamplight
- a still pond reflecting one warm light
### Usage
Hero images push the inked, warm-lit subject to one edge and leave the larger area as bare dark negative space for the headline overlay. One small vermilion seal mark is the only saturated colour.

# Andon shadcn/ui Components
Artifact: `component-recipes-v1`
Author: `katagami-ui-projection`
Language ID: `en-019efd71-ffc5-7861-957f-c3ebcd858420`
Slug: `andon`
## Intent
A night-and-paper interface language. The screen is a paper lantern grid on a deep sumi-indigo ground: every surface is a shoji cell, dark when resting and warm when it holds something live. It reads the same Japanese paper as its source but from the dark side — intentional emptiness becomes the dark ground itself, light becomes the message, and a single vermilion ember marks the one thing that needs a person.
## 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
- a strict shoji lattice of cells: resting cells sit dark, live cells warm from the top edge inward like washi lit from behind
- one vermilion ember seal pressed at a slight tilt marks the single reading that needs a person — one per board
- an upright reading rail names regions in the margin in mono, so the lattice itself stays wordless and lit
- a deep sumi-indigo night ground carries everything with a faint blue-grey kumiko grain crossing the field
- warm lantern amber is the whole live vocabulary; cool moon-indigo plays the quiet secondary

## 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/andon/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: light only the cells that are true right now and let the rest rest in the dark; use warm amber for live and reserve the vermilion ember for the one thing that needs a person; carry structure with light, surface, and the trailing rule before any border; keep region names in the upright reading rail so the lattice stays wordless; tune neutrals cool to the sumi-night ground
- Do not: do not default to white or wash the ground pale — the night is the point; do not add a second loud accent or flood the board with embers; do not frame every cell with a charcoal border or inset inner frame; do not centre everything or build perfectly symmetrical dashboards; do not animate with bounce, spring, or playful overshoot
## Copy-paste component example
This generated starter proves the import shape. Production Katagami agents should replace it with a language-specific product composition.
