# Ma Wabi-Sabi Spatial Minimalism shadcn/ui Components

Artifact: `component-recipes-v1`
Author: `katagami-ui-projection`
Language ID: `ma-wabi-sabi-spatial-minimalism`
Slug: `ma-wabi-sabi-spatial-minimalism`

## Intent

Ma Wabi-Sabi Spatial Minimalism translates Japanese ideas of interval, emptiness, quiet affordance, and imperfect material presence into a digital interface language. It draws from MUJI no-brand restraint, Kenya Hara’s idea of emptiness as an open vessel, Naoto Fukasawa’s without-thought product affordances, and Tadao Ando’s disciplined planes of concrete, light, and shadow. The language is not decorative minimalism; it is spatial editing. Every component earns its place by leaving enough silence around it for the user to understand function, hierarchy, and mood without visual coercion.

## 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`.

    "medium": 500,
    "semibold": 600,
    "bold": 700
  }
}

## Visual character to preserve

- A 12-column desktop grid with one deliberately empty left bay and asymmetrical content blocks offset into the remaining columns.
- Flat off-white paper panels with 1px stone borders and a single charcoal hairline accent on the leading edge of important containers.
- Large ma intervals: 48px to 96px gaps between major regions, leaving visible pause around forms, metrics, and navigation.
- Subtle concrete-paper texture made with low-opacity noise and thin horizontal shadow bands instead of gradients or decorative imagery.
- Square 0px corners on structural panels and controls, with only small tags and avatars using fully rounded 9999px pills.

## ShadSync visual profile

{
  "family": "paper-collage",
  "material": "paper",
  "contour": "pebble",
  "border": "solid",
  "underlay": true,
  "grain": true,
  "stickerBadges": false,

  "density": "balanced",
  "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/ma-wabi-sabi-spatial-minimalism/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 pure #FFFFFF for the main background and reserve warm off-white for paper surfaces only.; Keep letter-spacing at -0.02em on all text and rely on Noto Serif JP plus IBM Plex Sans for quiet authority.; Create at least one intentionally empty spatial bay in desktop layouts to make ma visible.; Use 0px square corners for structural UI, reserving 9999px only for tags, avatars, and tiny status pills.; Express hierarchy with hairlines, shadow, spacing, and type scale before adding color.; Let forms and controls feel tactile through border weight, inset edges, and measured hover fills.; Use muted earth accent sparingly for selected states, not as a brand wash.; Make imperfections subtle: texture should be barely visible and never reduce legibility.
- Do not: Do not use gradients, glossy cards, glassmorphism, neon, or crypto-style color washes.; Do not decorate with stereotypical Japanese motifs, brush fonts, red circles, waves, or floral patterns.; Do not fill every grid column; visible emptiness is part of the layout system.; Do not use random radii such as 8px, 12px, 20px, 32px, or 48px.; Do not center all content or make symmetrical landing-page sections.; Do not use pastel beige backgrounds in place of actual white and material surfaces.; Do not hide affordances so much that controls become ambiguous.; Do not add multiple accent colors; one muted earth accent is enough.

## Copy-paste component example

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

## Layout notes

{
  "density": "Medium-low density chosen to preserve ma; every cluster gets enough void to read as a deliberate pause rather than unused screen.",
  "grid": "Desktop uses a 12-column grid with 24px gutters and max width 1360px; column 1 is often left empty as ma, content spans columns 2-12 with nested 3/6/3 working regions.",
  "whitespace": "Whitespace is active structure. Use 48px minimum between primary regions, 64px around hero or decision areas, and 96px top/bottom intervals where a user should slow down.",
  "breakpoints": {
    "desktop": "1200px and above: 12 columns with empty ma bay",
    "tablet": "768px-1199px: 8 columns, ma bay becomes top interval",
    "mobile": "0-767px: single column, intervals reduce to 32px but remain visible"
  },
  "responsive": "Collapse side rails beneath the main panel on tablet, stack all panels on mobile, keep controls 44px minimum, and allow tables to become card rows rather than horizontal overflow."
