# Swiss Typographic Monochrome

## Philosophy

A monochrome interface language rooted in Swiss International Style: asymmetric grid composition, rigorous typographic hierarchy, and disciplined use of black rules on white fields so information feels editorial, objective, and exact rather than decorative.

### Values

- clarity through typographic structure instead of ornamental interface chrome
- asymmetric grid logic that creates tension while preserving order and scanability
- monochrome restraint where contrast, spacing, and rule lines do the expressive work

### Anti-Values

- soft decorative gradients or atmospheric effects
- playful rounded consumer-app styling that dilutes editorial authority

### Visual Character

- Large black typographic headlines sit in wide white fields with strict left alignment, using abrupt line breaks and compressed vertical spacing to create poster-like tension.
- Content modules are organized on an asymmetric editorial grid with oversized outer margins, narrow vertical gutters, and visible black hairline dividers that expose the underlying structure.
- Section labels and metadata appear in uppercase monospace microtype, often rotated vertically or isolated in small index blocks to contrast with the grotesk reading text.
- Cards and panels stay flat white with black 1px to 2px rules, letting negative space, line weight, and scale shifts carry hierarchy instead of shadows or color.

# Swiss Typographic Monochrome

## Overview

A monochrome interface language rooted in Swiss International Style: asymmetric grid composition, rigorous typographic hierarchy, and disciplined use of black rules on white fields so information feels editorial, objective, and exact rather than decorative.

### Values

- clarity through typographic structure instead of ornamental interface chrome
- asymmetric grid logic that creates tension while preserving order and scanability
- monochrome restraint where contrast, spacing, and rule lines do the expressive work

### Anti-Values

- soft decorative gradients or atmospheric effects
- playful rounded consumer-app styling that dilutes editorial authority

### Visual Character

- Large black typographic headlines sit in wide white fields with strict left alignment, using abrupt line breaks and compressed vertical spacing to create poster-like tension.
- Content modules are organized on an asymmetric editorial grid with oversized outer margins, narrow vertical gutters, and visible black hairline dividers that expose the underlying structure.
- Section labels and metadata appear in uppercase monospace microtype, often rotated vertically or isolated in small index blocks to contrast with the grotesk reading text.
- Cards and panels stay flat white with black 1px to 2px rules, letting negative space, line weight, and scale shifts carry hierarchy instead of shadows or color.

- **Style**: solid
- **Character**: Borders behave like editorial rule lines: thin, exact, and structural rather than decorative, used to expose the grid and separate information zones.

## Components

### Composition

Compose screens like a Swiss poster merged with a data dashboard: one dominant headline zone, one dense information rail, and modular content blocks locked to a visible column rhythm.

### Hierarchy

Use scale contrast first, then weight, then rule lines and spacing. Headlines should feel commanding, labels quiet, and data values precise and sharply aligned.

### Density

Medium-high density with disciplined whitespace: content can be plentiful, but every cluster must live inside a measured grid and preserve breathing room around major headlines.

### Signature Patterns

- Every major section begins with a monospace index label in a dedicated narrow column, separated from content by a vertical rule that stays visible across breakpoints.
- Primary cards use strong top borders and bottom-aligned metadata rows so panels feel like editorial slices of a larger composition instead of floating app widgets.
- Display statistics are rendered as oversized numerals with tightly tracked grotesk type, paired with tiny uppercase explanatory captions for stark scale contrast.
- Navigation and filters use rectangular controls with zero radius, black borders, and invert-on-hover states so interaction feels typographic and print-derived rather than skeuomorphic.

## 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-019da1b2-69f3-7620-bfc6-873af6b4751f/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 rules, scale contrast, and alignment as the primary expressive tools.

- Do Pair large editorial headlines with restrained monospace metadata to clarify reading order.
- Don't Do not introduce colorful accents, soft neumorphism, or glass effects.
- Don't Do not center everything; preserve asymmetric tension and left-anchored reading flow.
- Don't Do not hide structure behind oversized cards, rounded corners, or decorative shadows.

# Swiss Typographic Monochrome shadcn/ui Components

Artifact: `component-recipes-v1`
Author: `katagami-ui-projection`
Language ID: `en-019da1b2-69f3-7620-bfc6-873af6b4751f`
Slug: `swiss-typographic-monochrome`

## Intent

A monochrome interface language rooted in Swiss International Style: asymmetric grid composition, rigorous typographic hierarchy, and disciplined use of black rules on white fields so information feels editorial, objective, and exact rather than decorative.

## 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": "#2B2B2B",
  "accent": "#000000",
  "background": "#F7F7F2",
  "surface": "#FFFFFF",
  "text": "#111111",
  "muted": "#6D6D68",
  "border": "#141414",
  "error": "#7A0F0F",
  "success": "#0F3D22",
  "warning": "#6B5200",
  "info": "#202A44"
}

Typography:

{
  "heading_font": "Archivo",
  "body_font": "Archivo",
  "mono_font": "IBM Plex Mono",
  "base_size": "16px",
  "scale_ratio": 1.25,
  "line_height": 1.5,
  "letter_spacing": "0.01em",
  "google_fonts_url": "https://fonts.googleapis.com/css2?family=Archivo:wght@400;500;600;700;800&family=IBM+Plex+Mono:wght@400;500;600&display=swap"
}

## Visual character to preserve

- Large black typographic headlines sit in wide white fields with strict left alignment, using abrupt line breaks and compressed vertical spacing to create poster-like tension.
- Content modules are organized on an asymmetric editorial grid with oversized outer margins, narrow vertical gutters, and visible black hairline dividers that expose the underlying structure.
- Section labels and metadata appear in uppercase monospace microtype, often rotated vertically or isolated in small index blocks to contrast with the grotesk reading text.
- Cards and panels stay flat white with black 1px to 2px rules, letting negative space, line weight, and scale shifts carry hierarchy instead of shadows or color.

## ShadSync visual profile

{
  "family": "paper-collage",
  "material": "paper",
  "contour": "default",
  "border": "solid",
  "underlay": false,
  "grain": true,
  "stickerBadges": false,
  "motion": "lift-rotate",
  "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/swiss-typographic-monochrome/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 rules, scale contrast, and alignment as the primary expressive tools.; Keep components rectangular, flat, and grid-locked with visible structural seams.; Pair large editorial headlines with restrained monospace metadata to clarify reading order.
- Do not: Do not introduce colorful accents, soft neumorphism, or glass effects.; Do not center everything; preserve asymmetric tension and left-anchored reading flow.; Do not hide structure behind oversized cards, rounded corners, or decorative shadows.

## 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

{
  "grid": "A 12-column desktop editorial grid with a narrow index rail and wide content spans, collapsing to 8 columns on tablet and a single stacked column with retained rule lines on mobile.",
  "breakpoints": "Desktop 1440+, tablet 768-1439, mobile 375-767; preserve the index rail as a horizontal band on smaller screens rather than removing it.",
  "whitespace": "Use generous page margins and deliberate vertical rhythm, but compress spacing inside data clusters so contrast between macro-space and micro-density stays visible."
