Suzuri

# Suzuri

## Philosophy

Suzuri is the inkstone: a calm Japanese interface language that grinds structure from ma (intentional emptiness) instead of borders, anchored by a single hand-painted fude ink stroke and one vermilion hanko seal. A reimagining of Minimalist Japanese — its restraint and paper-and-ink soul kept, its expression renewed from framed panels to borderless planes floating on negative space.

### Values

- intentional emptiness (ma) as structure
- paper-and-ink tactility, near-monochrome
- one deliberate mark over many
- ritualized quiet hierarchy
- calm operational clarity

### Anti-Values

- borders and boxes as structure
- status as bright pill wallpaper
- ornamental clutter and loud gradients
- glossy skeuomorphism
- motion for spectacle

### Visual Character

- borderless warm-washi planes separated by ma and a soft grounded shadow, never a bordered card
- the fude ink stroke — a wet brushstroke that pools under the active nav item, focused control, or section heading, the only linework on the page
- the hanko seal — a small vermilion square stamped at a 2-degree tilt for status, counts, and confirmations, with ghost and ink variants
- a near-monochrome canvas where the single vermilion appears only as a stroke or a seal
- Mincho display over gothic body over mono uppercase labels for clear role separation

- **Lg**: 24px
- **Full**: 9999px

### Shadows

- **Sm**: 0 1px 2px rgba(26,22,19,0.05)
- **Md**: 0 10px 30px -12px rgba(26,22,19,0.14)

### Surfaces

- **Treatment**: warm washi paper with faint fiber grain; planes float on ma, never boxed by borders

- **Easing**: cubic-bezier(0.22, 1, 0.36, 1)
- **Philosophy**: ink settling into paper — a slow, deliberate ink-bleed reveal; never bounce, spring, or overshoot

## Rules

### Composition

Compose as editorial planes floating on ma: a dominant content plane, supporting planes, and at least one large quiet zone per major viewport. Nothing is fenced in a box; order comes from the empty room left around each thing.

### Hierarchy

Mincho headlines each carry a fude ink stroke; gothic body carries operational text; mono uppercase carries labels and counts. Emphasis is position, space, one ink stroke, and one vermilion seal — never many weights or many colors.

### Density

Low-to-medium. Controls are compact but never cramped; planes breathe with oversized padding; every cluster is separated by space rather than dividers.

### Signature Patterns

- the fude ink stroke pools beneath the active/focused element and every section heading — the page's only linework
- status, counts, and confirmations appear as a small vermilion hanko square rotated 2 degrees, with ghost and ink variants, never a bright pill
- cards are borderless paper planes on a soft grounded shadow, separated by ma; navigation breathes as part of the page, never trapped in a pill or floating card
- the canvas stays near-monochrome washi-and-ink; the single vermilion is reserved for one earned stroke or seal per view
- imagery is sumi-e ink wash in the Kasumi hand — a subject in a few strokes floated in vast negative space, sealed with one hanko

## Layout

### Grid

Desktop composes a dominant content plane beside supporting planes on a warm-paper ground; the dashboard side rail is space and type, not a boxed sidebar. Planes align to a calm editorial rhythm with at least one deliberate quiet zone.

### Breakpoints

1200px+ full editorial spread; 1024px compressed two-plane layout; tablet 768-1024 is designed as its own band (two-up planes, wrapped nav, centred hero art), never the mobile column stretched wide; 390px single column with clamped, wrapping display headlines, collapsed nav, and tables that scroll inside their plane.

### Whitespace

Whitespace is structural: 40-96px outer margins on desktop, 24-40px on tablet, 16-24px on phone. Never fill every cell; preserve blank planes to set the rhythm.

## Guidance

### Do

- let ma and alignment carry structure before any line or fill
- reserve the vermilion for the one stroke or seal that earns a pause
- pair Mincho display with gothic body and mono labels for clear role separation
- keep planes borderless with a soft grounded shadow and generous padding
- render imagery as sumi-e ink wash floated in negative space

### Don't

- do not draw borders or boxes to group things
- do not turn status into bright pills or stamp the seal until it is wallpaper
- do not use glossy gradients, heavy shadows, or playful overshoot
- do not trap navigation in a floating pill or nest cards
- do not let copy sit on the busy part of the ink imagery

## Imagery Direction

### Pairs With

kasumi

### Summary

Sumi-e ink wash on warm washi in the Kasumi hand: any subject reduced to a few confident calligraphic strokes with graded bleed and dry-brush kasure, floated in vast negative space, sealed with one small vermilion hanko. Monochrome ink plus the single seal; copy never contests the busy part of the ink.

### Hero

one subject entering from an edge, the rest of the frame left as warm-paper ma for text overlay

### Palette

charcoal sumi ink on warm off-white washi, with a single vermilion seal

# Suzuri

## Overview

Suzuri is the inkstone: a calm Japanese interface language that grinds structure from ma (intentional emptiness) instead of borders, anchored by a single hand-painted fude ink stroke and one vermilion hanko seal. A reimagining of Minimalist Japanese — its restraint and paper-and-ink soul kept, its expression renewed from framed panels to borderless planes floating on negative space.

### Values

- intentional emptiness (ma) as structure
- paper-and-ink tactility, near-monochrome
- one deliberate mark over many
- ritualized quiet hierarchy
- calm operational clarity

### Anti-Values

- borders and boxes as structure
- status as bright pill wallpaper
- ornamental clutter and loud gradients
- glossy skeuomorphism
- motion for spectacle

### Visual Character

- borderless warm-washi planes separated by ma and a soft grounded shadow, never a bordered card
- the fude ink stroke — a wet brushstroke that pools under the active nav item, focused control, or section heading, the only linework on the page
- the hanko seal — a small vermilion square stamped at a 2-degree tilt for status, counts, and confirmations, with ghost and ink variants
- a near-monochrome canvas where the single vermilion appears only as a stroke or a seal
- Mincho display over gothic body over mono uppercase labels for clear role separation

## Layout

### Spacing Tokens

- **Base**: `8px`

### Grid

Desktop composes a dominant content plane beside supporting planes on a warm-paper ground; the dashboard side rail is space and type, not a boxed sidebar. Planes align to a calm editorial rhythm with at least one deliberate quiet zone.

### Breakpoints

1200px+ full editorial spread; 1024px compressed two-plane layout; tablet 768-1024 is designed as its own band (two-up planes, wrapped nav, centred hero art), never the mobile column stretched wide; 390px single column with clamped, wrapping display headlines, collapsed nav, and tables that scroll inside their plane.

### Whitespace

Whitespace is structural: 40-96px outer margins on desktop, 24-40px on tablet, 16-24px on phone. Never fill every cell; preserve blank planes to set the rhythm.

## Elevation & Depth

### Shadows

- **Sm**: 0 1px 2px rgba(26,22,19,0.05)
- **Md**: 0 10px 30px -12px rgba(26,22,19,0.14)
- **Lg**: 0 26px 60px -20px rgba(26,22,19,0.18)

## Shapes

### Rounded

- **None**: `0px`
- **Md**: `16px`
- **Lg**: `24px`
- **Full**: `9999px`

### Surfaces

- **Treatment**: warm washi paper with faint fiber grain; planes float on ma, never boxed by borders
- **Card Style**: borderless paper planes separated by whitespace and a soft grounded shadow; a single fude ink-stroke underline anchors each heading
- **Bg Pattern**: very faint horizontal paper-fiber grain, no visible lines

### Borders

- **Default Width**: 0px
- **Accent Width**: 0px
- **Style**: none
- **Character**: structure comes from ma and alignment, not lines; the only linework is the hand-painted fude ink stroke under active elements and headings

## Components

### Composition

Compose as editorial planes floating on ma: a dominant content plane, supporting planes, and at least one large quiet zone per major viewport. Nothing is fenced in a box; order comes from the empty room left around each thing.

### Hierarchy

Mincho headlines each carry a fude ink stroke; gothic body carries operational text; mono uppercase carries labels and counts. Emphasis is position, space, one ink stroke, and one vermilion seal — never many weights or many colors.

### Density

Low-to-medium. Controls are compact but never cramped; planes breathe with oversized padding; every cluster is separated by space rather than dividers.

### Signature Patterns

- the fude ink stroke pools beneath the active/focused element and every section heading — the page's only linework
- status, counts, and confirmations appear as a small vermilion hanko square rotated 2 degrees, with ghost and ink variants, never a bright pill
- cards are borderless paper planes on a soft grounded shadow, separated by ma; navigation breathes as part of the page, never trapped in a pill or floating card
- the canvas stays near-monochrome washi-and-ink; the single vermilion is reserved for one earned stroke or seal per view
- imagery is sumi-e ink wash in the Kasumi hand — a subject in a few strokes floated in vast negative space, sealed with one hanko

## 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-019f7075-7fac-75a1-8a78-f2cb695c897e/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 let ma and alignment carry structure before any line or fill
- Do reserve the vermilion for the one stroke or seal that earns a pause
- Do pair Mincho display with gothic body and mono labels for clear role separation
- Do keep planes borderless with a soft grounded shadow and generous padding
- Do render imagery as sumi-e ink wash floated in negative space
- Don't do not draw borders or boxes to group things
- Don't do not turn status into bright pills or stamp the seal until it is wallpaper
- Don't do not use glossy gradients, heavy shadows, or playful overshoot
- Don't do not trap navigation in a floating pill or nest cards
- Don't do not let copy sit on the busy part of the ink imagery
