summary
Shuimo Mist draws from the Chinese ink wash painting tradition (水墨画) where empty space speaks as loudly as ink. Interfaces dissolve into atmospheric layers like mountain peaks emerging from morning fog. Every element carries qi — the breath of life — through careful balance of weight and void. The aesthetic prizes contemplation over urgency, depth over flatness, and the beauty of impermanence captured in a single brushstroke.

guidance
do
  • Use ink-density gradation as the primary visual hierarchy mechanism
  • Allow generous whitespace between content groups — let the page breathe

  • Use backdrop-filter blur to create atmospheric depth between layers
  • Reserve vermillion red (#c53d2d) exclusively for the single primary action per screen
  • Employ radial-gradient ink washes as subtle background textures
  • Use Noto Serif SC for headings to evoke classical Chinese typography
  • Transition all interactive states with slow meditative easing (400-500ms)
  • Tint shadows warm brown — never use pure black or blue shadows
  • Let decorative brush-stroke SVGs serve as organic section dividers
avoid
  • Never use more than one vermillion accent element per viewport
  • Never apply pure white (#fff) backgrounds — always use warm paper tones
  • Never use sharp mechanical borders — prefer soft, slightly diffused edges
  • Never crowd elements together — minimum 16px gap between interactive elements
  • Never use saturated colors besides the vermillion accent
  • Never apply fast transitions under 300ms — this aesthetic is unhurried
  • Never use blue-tinted or cool-gray shadows
  • Never place text below 13px size — legibility on warm backgrounds requires generous sizing
  • Never use more than 3 levels of visual hierarchy on a single screen

# Shuimo Mist

## Philosophy

Shuimo Mist draws from the Chinese ink wash painting tradition (水墨画) where empty space speaks as loudly as ink. Interfaces dissolve into atmospheric layers like mountain peaks emerging from morning fog. Every element carries qi — the breath of life — through careful balance of weight and void. The aesthetic prizes contemplation over urgency, depth over flatness, and the beauty of impermanence captured in a single brushstroke.

### Values

- Qi (气) — Life-breath flows through whitespace and rhythm
- Xu (虚) — Emptiness is not absence but pregnant potential
- Yi (意) — Intent precedes form; every element has purpose
- Mo (墨) — Ink gradation creates infinite depth from a single material
- Jing (静) — Stillness and contemplation over urgency
- He (和) — Harmony between opposing weights and densities
- Gu (古) — Respect for tradition while serving modern function

### Anti-Values

- Never assault with saturated color or competing focal points
- Never fill space anxiously — trust the void to communicate
- Never use mechanical precision where organic softness belongs
- Never rush the eye — allow unhurried visual journeys

### Visual Character

- background: radial-gradient(ellipse at 30% 20%, rgba(60,56,50,0.06) 0%, transparent 70%)
- box-shadow: 0 4px 24px rgba(45,42,38,0.08)
- backdrop-filter: blur(8px) saturate(1.1)
- border: 1px solid rgba(60,56,50,0.12)
- transition: all 450ms cubic-bezier(0.4, 0, 0.2, 1)

## Rules

### Composition

Arrange elements as a shanshui painter composes a landscape — primary content anchored like a mountain peak with supporting elements dissolving toward edges. Asymmetric balance preferred. Allow generous negative space as breathing room. Content flows vertically when culturally appropriate, horizontally for scanning.

### Hierarchy

Use ink density as the primary hierarchy signal. Most important elements rendered in concentrated ink (#1a1714), secondary in medium wash (#5c564e), tertiary fading to diluted tones (#8c8070). Size differences follow the 1.25 modular scale. Vermillion red reserved exclusively for the single most important action on any screen.

### Density

Low-to-medium density. Generous padding (24-48px between sections). No more than 3-4 distinct content groups visible without scrolling. Each group separated by atmospheric whitespace, not dividers. When data tables are needed, keep rows airy with 16px vertical padding.

### Signature Patterns

- Ink diffusion backgrounds — overlapping radial-gradient layers with very soft color stops creating watercolor-like atmospheric depth behind content
- Floating mist panels — cards with backdrop-filter blur and semi-transparent warm backgrounds that appear to hover in fog
- Vermillion seal badges — small accent markers styled like traditional Chinese seal stamps (square, slightly rotated, red on cream)
- Brush-stroke dividers — decorative SVG elements mimicking single horizontal ink brush strokes as section separators
- Paper-edge borders — subtle warm-toned borders with slight irregularity suggesting handmade paper edges

## Guidance

### Do

- Use ink-density gradation as the primary visual hierarchy mechanism
- Allow generous whitespace between content groups — let the page breathe
- Apply warm paper tones (#f5f0e8) as the base for all backgrounds
- Use backdrop-filter blur to create atmospheric depth between layers
- Reserve vermillion red (#c53d2d) exclusively for the single primary action per screen
- Employ radial-gradient ink washes as subtle background textures
- Use Noto Serif SC for headings to evoke classical Chinese typography
- Transition all interactive states with slow meditative easing (400-500ms)
- Tint shadows warm brown — never use pure black or blue shadows
- Let decorative brush-stroke SVGs serve as organic section dividers

### Don't

- Never use more than one vermillion accent element per viewport
- Never apply pure white (#fff) backgrounds — always use warm paper tones
- Never use sharp mechanical borders — prefer soft, slightly diffused edges
- Never crowd elements together — minimum 16px gap between interactive elements
- Never use saturated colors besides the vermillion accent
- Never apply fast transitions under 300ms — this aesthetic is unhurried
- Never use blue-tinted or cool-gray shadows
- Never place text below 13px size — legibility on warm backgrounds requires generous sizing
- Never use more than 3 levels of visual hierarchy on a single screen

### Usage Context

Ideal for creative, contemplative, and cultural applications — poetry editors, art galleries, meditation apps, journaling tools, knowledge gardens, and any interface where the user benefits from an unhurried, atmospheric experience. Not suitable for high-density data dashboards or time-critical operational interfaces.

### Accessibility

Contrast ratios maintained at WCAG AA minimum (4.5:1 for body text, 3:1 for large text). Body text #1a1714 on #f5f0e8 achieves 12.3:1. Muted text #8c8070 on #f5f0e8 achieves 4.1:1 — use only for supplementary labels at 16px+. All interactive elements have visible focus rings using the ink-dark color. Motion respects prefers-reduced-motion by collapsing to instant transitions.

# Shuimo Mist

## Overview

Shuimo Mist draws from the Chinese ink wash painting tradition (水墨画) where empty space speaks as loudly as ink. Interfaces dissolve into atmospheric layers like mountain peaks emerging from morning fog. Every element carries qi — the breath of life — through careful balance of weight and void. The aesthetic prizes contemplation over urgency, depth over flatness, and the beauty of impermanence captured in a single brushstroke.

### Values

- Qi (气) — Life-breath flows through whitespace and rhythm
- Xu (虚) — Emptiness is not absence but pregnant potential
- Yi (意) — Intent precedes form; every element has purpose
- Mo (墨) — Ink gradation creates infinite depth from a single material
- Jing (静) — Stillness and contemplation over urgency
- He (和) — Harmony between opposing weights and densities
- Gu (古) — Respect for tradition while serving modern function

### Anti-Values

- Never assault with saturated color or competing focal points
- Never fill space anxiously — trust the void to communicate
- Never use mechanical precision where organic softness belongs
- Never rush the eye — allow unhurried visual journeys

### Visual Character

- background: radial-gradient(ellipse at 30% 20%, rgba(60,56,50,0.06) 0%, transparent 70%)
- box-shadow: 0 4px 24px rgba(45,42,38,0.08)
- backdrop-filter: blur(8px) saturate(1.1)
- border: 1px solid rgba(60,56,50,0.12)
- transition: all 450ms cubic-bezier(0.4, 0, 0.2, 1)

## Components

### Composition

Arrange elements as a shanshui painter composes a landscape — primary content anchored like a mountain peak with supporting elements dissolving toward edges. Asymmetric balance preferred. Allow generous negative space as breathing room. Content flows vertically when culturally appropriate, horizontally for scanning.

### Hierarchy

Use ink density as the primary hierarchy signal. Most important elements rendered in concentrated ink (#1a1714), secondary in medium wash (#5c564e), tertiary fading to diluted tones (#8c8070). Size differences follow the 1.25 modular scale. Vermillion red reserved exclusively for the single most important action on any screen.

### Density

Low-to-medium density. Generous padding (24-48px between sections). No more than 3-4 distinct content groups visible without scrolling. Each group separated by atmospheric whitespace, not dividers. When data tables are needed, keep rows airy with 16px vertical padding.

### Signature Patterns

- Ink diffusion backgrounds — overlapping radial-gradient layers with very soft color stops creating watercolor-like atmospheric depth behind content
- Floating mist panels — cards with backdrop-filter blur and semi-transparent warm backgrounds that appear to hover in fog
- Vermillion seal badges — small accent markers styled like traditional Chinese seal stamps (square, slightly rotated, red on cream)
- Brush-stroke dividers — decorative SVG elements mimicking single horizontal ink brush strokes as section separators
- Paper-edge borders — subtle warm-toned borders with slight irregularity suggesting handmade paper edges

## 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-019dacc3-d6b4-7ff2-b61a-62cbb72a9071/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.

# Shuimo Mist shadcn/ui Components

Artifact: `component-recipes-v1`
Author: `katagami-ui-projection`
Language ID: `en-019dacc3-d6b4-7ff2-b61a-62cbb72a9071`
Slug: `shuimo-mist`

## Intent

Shuimo Mist draws from the Chinese ink wash painting tradition (水墨画) where empty space speaks as loudly as ink. Interfaces dissolve into atmospheric layers like mountain peaks emerging from morning fog. Every element carries qi — the breath of life — through careful balance of weight and void. The aesthetic prizes contemplation over urgency, depth over flatness, and the beauty of impermanence captured in a single brushstroke.

## 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`.

}

## 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/shuimo-mist/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 ink-density gradation as the primary visual hierarchy mechanism; Allow generous whitespace between content groups — let the page breathe; Apply warm paper tones (#f5f0e8) as the base for all backgrounds; Use backdrop-filter blur to create atmospheric depth between layers; Reserve vermillion red (#c53d2d) exclusively for the single primary action per screen; Employ radial-gradient ink washes as subtle background textures; Use Noto Serif SC for headings to evoke classical Chinese typography; Transition all interactive states with slow meditative easing (400-500ms); Tint shadows warm brown — never use pure black or blue shadows; Let decorative brush-stroke SVGs serve as organic section dividers
- Do not: Never use more than one vermillion accent element per viewport; Never apply pure white (#fff) backgrounds — always use warm paper tones; Never use sharp mechanical borders — prefer soft, slightly diffused edges; Never crowd elements together — minimum 16px gap between interactive elements; Never use saturated colors besides the vermillion accent; Never apply fast transitions under 300ms — this aesthetic is unhurried; Never use blue-tinted or cool-gray shadows; Never place text below 13px size — legibility on warm backgrounds requires generous sizing; Never use more than 3 levels of visual hierarchy on a single screen

## Copy-paste component example

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