composition
Use a rectilinear architectural plan: broad cream canvas, asymmetric hero module, right-hand material library, and smaller bounded pattern samples that never compete with the primary task.
density

Balanced residential studio density: many objects may appear, but generous cream gutters and grouped panels keep the interface breathable.

signature patterns
Memphis inlay rails: horizontal or vertical bars split into cobalt, tomato, butter, teal, and lilac blocks clipped inside black outlines.Terrazzo wells: selected cards use layered radial-gradient speckles masked to a counter, sample tile, or side panel surface only.Drafted-symbol corners: tiny circles, stepped arches, checker chips, and squiggle rules attach to corners to label zones and states.Offset slab depth: important panels cast hard black or color slab shadows instead of blur, producing furniture-like object presence.Sculptural aperture modules: one circular fireplace/fixture preview breaks the grid and gives the system its postmodern architectural reference.

grid

12-column desktop grid with 24px gutters; tablet collapses to 6 columns; mobile becomes single column with pattern rails retained as narrow strips.

whitespace

Cream whitespace acts like wall surface; leave 24-48px around major modules and keep decorative fragments close to their parent component.

# Livable Neo-Memphis Surface Play

## Philosophy

A residential postmodern language for calm home-planning software: warm cream architecture, bounded Memphis color, stone-like speckles, black drafted lines, and playful surface inlays used as functional wayfinding rather than all-over decoration.

### Values

- play contained by architecture
- material contrast with domestic warmth
- legible symbolic surfaces
- color as room-scale zoning
- productizable pattern without visual overload

### Anti-Values

- room-wide novelty wallpaper
- generic white SaaS dashboards
- nostalgic 1980s pastiche without livability
- unbounded rainbow accents

### Visual Character

- Warm ivory page fields with black 2px drafting outlines, square-corner panels, and offset shadow slabs that read like architectural elevation drawings.
- Cobalt, tomato, butter, teal, and lilac appear as bounded block inlays on headers, tabs, handles, and status strips rather than full-screen color washes.
- Terrazzo-like micro speckles are clipped to countertops, side rails, and selected cards using radial-gradient layers over cream and pale lilac surfaces.
- Small checker fragments, squiggle dividers, and geometric arch/circle markers are anchored to component corners as wayfinding symbols, not loose confetti.
- Dense product data sits in calm rectilinear grids while one sculptural fireplace or fixture module breaks the grid with a circular or stepped silhouette.

# Livable Neo-Memphis Surface Play

## Overview

A residential postmodern language for calm home-planning software: warm cream architecture, bounded Memphis color, stone-like speckles, black drafted lines, and playful surface inlays used as functional wayfinding rather than all-over decoration.

### Values

- play contained by architecture
- material contrast with domestic warmth
- legible symbolic surfaces
- color as room-scale zoning
- productizable pattern without visual overload

### Anti-Values

- room-wide novelty wallpaper
- generic white SaaS dashboards
- nostalgic 1980s pastiche without livability
- unbounded rainbow accents

### Visual Character

- Warm ivory page fields with black 2px drafting outlines, square-corner panels, and offset shadow slabs that read like architectural elevation drawings.
- Cobalt, tomato, butter, teal, and lilac appear as bounded block inlays on headers, tabs, handles, and status strips rather than full-screen color washes.
- Terrazzo-like micro speckles are clipped to countertops, side rails, and selected cards using radial-gradient layers over cream and pale lilac surfaces.
- Small checker fragments, squiggle dividers, and geometric arch/circle markers are anchored to component corners as wayfinding symbols, not loose confetti.
- Dense product data sits in calm rectilinear grids while one sculptural fireplace or fixture module breaks the grid with a circular or stepped silhouette.

## Components

### Composition

Use a rectilinear architectural plan: broad cream canvas, asymmetric hero module, right-hand material library, and smaller bounded pattern samples that never compete with the primary task.

### Density

Balanced residential studio density: many objects may appear, but generous cream gutters and grouped panels keep the interface breathable.

### Hierarchy

Headlines use soft high-contrast Fraunces; operational labels and values use Nunito Sans; Space Mono is reserved for dimensions, SKUs, coordinates, and room codes.

### Signature Patterns

- Memphis inlay rails: horizontal or vertical bars split into cobalt, tomato, butter, teal, and lilac blocks clipped inside black outlines.
- Terrazzo wells: selected cards use layered radial-gradient speckles masked to a counter, sample tile, or side panel surface only.
- Drafted-symbol corners: tiny circles, stepped arches, checker chips, and squiggle rules attach to corners to label zones and states.
- Offset slab depth: important panels cast hard black or color slab shadows instead of blur, producing furniture-like object presence.
- Sculptural aperture modules: one circular fireplace/fixture preview breaks the grid and gives the system its postmodern architectural reference.

## 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-019e6676-a14e-7752-880f-51899a2b8d48/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 Use black linework to make playful color feel architectural and precise.
- Do Clip patterns to useful surfaces such as samples, section headers, selected rows, and navigation handles.
- Do Pair one sculptural object with otherwise calm rectangular task areas.
- Do Keep background warm and quiet so saturated colors remain bounded accents.
- Don't Do not flood the whole screen with Memphis squiggles or checkerboards.
- Don't Do not use soft glassmorphism, generic gray SaaS cards, or blurred gradient blobs.
- Don't Do not round every container into friendly pills; most architecture remains squared.
- Don't Do not treat historical postmodern references as ironic stickers divorced from product meaning.

# Livable Neo-Memphis Surface Play shadcn/ui Components

Artifact: `component-recipes-v1`
Author: `katagami-ui-projection`
Language ID: `en-019e6676-a14e-7752-880f-51899a2b8d48`
Slug: `livable-neo-memphis-surface-play`

## Intent

A residential postmodern language for calm home-planning software: warm cream architecture, bounded Memphis color, stone-like speckles, black drafted lines, and playful surface inlays used as functional wayfinding rather than all-over decoration.

## 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:

{
  "accent": "#F2C94C",
  "background": "#FFF7E8",
  "border": "#181614",
  "error": "#B7322C",
  "info": "#5C55B8",
  "muted": "#786F64",
  "primary": "#1646A8",
  "secondary": "#E24B32",
  "success": "#0E7C66",
  "surface": "#FFFCF2",
  "text": "#181614",
  "warning": "#D99A18"
}

Typography:

{
  "base_size": "16px",
  "body_font": "Nunito Sans",
  "google_fonts_url": "https://fonts.googleapis.com/css2?family=Fraunces:opsz,wght@9..144,600;9..144,750&family=Nunito+Sans:wght@400;600;700;800&family=Space+Mono:wght@400;700&display=swap",
  "heading_font": "Fraunces",
  "letter_spacing": "-0.01em",
  "line_height": 1.48,
  "mono_font": "Space Mono",
  "scale_ratio": 1.22
}

## Visual character to preserve

- Warm ivory page fields with black 2px drafting outlines, square-corner panels, and offset shadow slabs that read like architectural elevation drawings.
- Cobalt, tomato, butter, teal, and lilac appear as bounded block inlays on headers, tabs, handles, and status strips rather than full-screen color washes.
- Terrazzo-like micro speckles are clipped to countertops, side rails, and selected cards using radial-gradient layers over cream and pale lilac surfaces.
- Small checker fragments, squiggle dividers, and geometric arch/circle markers are anchored to component corners as wayfinding symbols, not loose confetti.
- Dense product data sits in calm rectilinear grids while one sculptural fireplace or fixture module breaks the grid with a circular or stepped silhouette.

}

## 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/livable-neo-memphis-surface-play/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 black linework to make playful color feel architectural and precise.; Clip patterns to useful surfaces such as samples, section headers, selected rows, and navigation handles.; Pair one sculptural object with otherwise calm rectangular task areas.; Keep background warm and quiet so saturated colors remain bounded accents.
- Do not: Do not flood the whole screen with Memphis squiggles or checkerboards.; Do not use soft glassmorphism, generic gray SaaS cards, or blurred gradient blobs.; Do not round every container into friendly pills; most architecture remains squared.; Do not treat historical postmodern references as ironic stickers divorced from product meaning.

## Copy-paste component example

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