Establish priority through typographic size, weight, alignment, and distance; reserve color for state, focus, and small metadata cues.

Default to low-to-medium density with clusters separated by 32px or more, then compress only repeated data rows.

# Tokenized Spatial Minimalism

## Philosophy

A restrained product-design language where spatial rhythm is the primary ornament: hierarchy, grouping, and affordance emerge from measured whitespace, quiet grids, typographic restraint, and components reduced to their semantic minimum.

### Values

- Spacing tokens carry expression before color or decoration.
- Every component exposes one clear purpose with minimum chrome.
- Hierarchy is built through scale, alignment, and whitespace rather than saturated color.
- Neutral surfaces and accessible contrast keep attention on content and task flow.

### Anti-Values

- Decorative gradients, pictorial motifs, and ornamental shadows.
- Dense interfaces where proximity and alignment do not communicate structure.
- Novel controls that hide common affordances behind clever styling.

### Visual Character

- A visible-but-subtle 12-column grid and baseline rhythm align headings, cards, controls, and metrics with generous gutters.
- Spacing scale labels and CSS custom properties appear as small mono annotations, turning whitespace into the system signature.
- Components use one-pixel borders, square-to-soft radii, and no decorative fills beyond near-neutral surface steps.
- Typography uses restrained weight shifts, compact letter spacing for headings, and long line-height for readable quiet hierarchy.

# Tokenized Spatial Minimalism

## Overview

A restrained product-design language where spatial rhythm is the primary ornament: hierarchy, grouping, and affordance emerge from measured whitespace, quiet grids, typographic restraint, and components reduced to their semantic minimum.

### Values

- Spacing tokens carry expression before color or decoration.
- Every component exposes one clear purpose with minimum chrome.
- Hierarchy is built through scale, alignment, and whitespace rather than saturated color.
- Neutral surfaces and accessible contrast keep attention on content and task flow.

### Anti-Values

- Decorative gradients, pictorial motifs, and ornamental shadows.
- Dense interfaces where proximity and alignment do not communicate structure.
- Novel controls that hide common affordances behind clever styling.

### Visual Character

- A visible-but-subtle 12-column grid and baseline rhythm align headings, cards, controls, and metrics with generous gutters.
- Spacing scale labels and CSS custom properties appear as small mono annotations, turning whitespace into the system signature.
- Components use one-pixel borders, square-to-soft radii, and no decorative fills beyond near-neutral surface steps.
- Typography uses restrained weight shifts, compact letter spacing for headings, and long line-height for readable quiet hierarchy.

## Colors

Use the YAML color tokens as the normative palette. The prose below names the roles agents should preserve when generating UI.

## 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-019dde37-19ed-7333-8483-7338e10de68f/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.

# Tokenized Spatial Minimalism shadcn/ui Components

Artifact: `component-recipes-v1`
Author: `katagami-ui-projection`
Language ID: `en-019dde37-19ed-7333-8483-7338e10de68f`
Slug: `tokenized-spatial-minimalism`

## Intent

A restrained product-design language where spatial rhythm is the primary ornament: hierarchy, grouping, and affordance emerge from measured whitespace, quiet grids, typographic restraint, and components reduced to their semantic minimum.

## 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`.

## Token cues

Colors:

{
  "primary": "#111111",
  "secondary": "#3F3F46",
  "accent": "#6B7280",
  "background": "#FAFAF8",
  "surface": "#FFFFFF",
  "text": "#18181B",
  "muted": "#71717A",
  "border": "#D4D4D8",
  "error": "#B42318",
  "success": "#0F766E",
  "warning": "#A16207",
  "info": "#2563EB"
}

Typography:

{
  "heading_font": "Geist",
  "body_font": "Geist",
  "mono_font": "Geist Mono",
  "base_size": "16px",
  "scale_ratio": 1.2,
  "line_height": 1.55,
  "letter_spacing": "-0.025em",
  "google_fonts_url": "https://fonts.googleapis.com/css2?family=Geist:wght@400;500;600;700&family=Geist+Mono:wght@400;500;600&display=swap"
}

## Visual character to preserve

- A visible-but-subtle 12-column grid and baseline rhythm align headings, cards, controls, and metrics with generous gutters.
- Spacing scale labels and CSS custom properties appear as small mono annotations, turning whitespace into the system signature.
- Components use one-pixel borders, square-to-soft radii, and no decorative fills beyond near-neutral surface steps.
- Typography uses restrained weight shifts, compact letter spacing for headings, and long line-height for readable quiet hierarchy.

## ShadSync visual profile

{
  "family": "system",
  "material": "flat",
  "contour": "default",
  "border": "solid",
  "underlay": false,
  "grain": false,
  "stickerBadges": false,
  "motion": "still",
  "density": "dense",
  "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/tokenized-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 neutral surfaces, one-pixel borders, and clear focus rings to preserve accessibility.; Let consistent spacing communicate grouping before adding dividers or labels.; Keep component copy short, direct, and aligned to the grid.; Annotate major spatial intervals when presenting system or dashboard screens.
- Do not: Do not add gradients, illustrations, heavy shadows, or decorative icons to create excitement.; Do not use color as the only indicator of state or hierarchy.; Do not compress unrelated controls into the same spatial cluster.; Do not introduce custom widgets when native patterns would be clearer.

## Copy-paste component example

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