summary
Swiss International Style translates modernist clarity into interface systems: objective hierarchy, mathematical spacing, rigorous left alignment, and typography that behaves like an industrial standard rather than personal expression. The interface should feel like a timetable, poster grid, or transit information panel—lucid under pressure, spare without being empty, and persuasive through order rather than decoration.

rules
composition
Build compositions on a disciplined modular grid with a persistent metadata rail at the left, content blocks spanning controlled column widths, and strong flush-left alignment. Major zones should be separated by open space and hairline rules rather than nested boxes.
hierarchy
Hierarchy comes from scale jumps, weight changes, red signal markers, and the position of content within the grid. Headlines are oversized and terse; supporting data is compact, uppercase, and mono or utility-sized.
density
Medium information density with high legibility: generous margins, compressed leading in headlines, and tightly ordered tables. No decorative padding inflation inside controls; whitespace should feel intentional and architectural.
signature patterns
every major section begins with a narrow red vertical bar anchored to the left grid edgemodule boundaries are drawn with 1px horizontal hairline rules instead of rounded cards or shadowssection index numbers live in an oversized left rail and remain visually detached from the main content blockall utility labels are uppercase with aggressive letter-spacing and aligned on a common baseline gridtables, forms, and tabs use monochrome fields with black underlines or perimeter rules rather than filled controls
layout
grid
Desktop uses a 12-column asymmetrical grid: a fixed metadata rail plus flexible content columns. Key content spans 7–9 columns while summaries and controls occupy shorter bands. Tablet shifts to 8 columns with the metadata rail reduced; phone collapses to a single column with index markers becoming inline headers.
breakpoints
At 1024px reduce from 12 to 8 columns and tighten outer margins. At 768px stack the hero and operational panels vertically while preserving rule-based separators. At 480px convert all multi-column rows to a single column, make actions full-width, and allow tables to scroll horizontally inside ruled wrappers.
whitespace
Whitespace is structural: outer margins are large, inter-section spacing is 48–64px on desktop, and internal content uses an 8px baseline grid. Negative space should frame typography like poster composition rather than fill gaps evenly.
guidance
- Use red sparingly as a positional signal, not as a general decorative fill.
- Keep all major text flush-left and let rag create the visual rhythm.
- Separate information blocks with rules and spacing instead of extra containers.
- Use tabular mono text for schedules, codes, and numeric summaries.
- Let typography carry emphasis before reaching for color or iconography.
- Do not center headlines or balance pages symmetrically.
- Do not introduce rounded corners, soft shadows, or glass effects.
- Do not use multiple accent colors or illustrative gradients.
- Do not wrap every region in thick boxes that destroy the open grid.
- Do not make controls look tactile; they should feel engineered and flat.

# Swiss International Style
## Overview
Swiss International Style translates modernist clarity into interface systems: objective hierarchy, mathematical spacing, rigorous left alignment, and typography that behaves like an industrial standard rather than personal expression. The interface should feel like a timetable, poster grid, or transit information panel—lucid under pressure, spare without being empty, and persuasive through order rather than decoration.
### Values
- grid discipline over improvisation
- objective communication over stylistic flourish
- flush-left typographic hierarchy with measured rhythm
- contrast through scale, weight, and placement rather than ornament
- modular systems that feel reproducible across signage, print, and interface
### Anti-Values
- skeuomorphic texture
- centered ornamental composition
- rounded friendly softness
- decorative drop shadows and gratuitous gradients
- ambiguous hierarchy or inconsistent alignment
### Visual Character
- strict asymmetric grid with an oversized left rail used for section indices and metadata
- hairline black rules separating modules, rows, and headings with no decorative framing
- large neo-grotesk headlines set flush-left with tight leading and generous negative space around them
- small uppercase utility labels tracked wide and aligned to a consistent baseline grid
- a limited white-black palette punctuated by one urgent signal red used as vertical bars, dots, and action accents
## Colors
Use the YAML color tokens as the normative palette. The prose below names the roles agents should preserve when generating UI.
| Token | Value |
|-------|-------|
| primary | `#111111` |
| secondary | `#F5F3EE` |
| accent | `#D62828` |
| background | `#ECE9E1` |
| surface | `#FCFBF7` |
| text | `#121212` |
| muted | `#6F6A63` |
| border | `#1A1A1A` |
| error | `#B00020` |
| success | `#1D6B3C` |
| warning | `#B26A00` |
| info | `#005F8C` |
## Typography
- **Headline-Lg**: Helvetica Neue, Arial, sans-serif, 1.953rem, weight 700, line-height 1.1.
- **Headline-Md**: Helvetica Neue, Arial, sans-serif, 1.563rem, weight 600, line-height 1.15.
- **Body-Md**: IBM Plex Sans, Arial, sans-serif, 16px, weight 400, line-height 1.5.
- **Label-Md**: IBM Plex Mono, monospace, 0.75rem, weight 600, line-height 1.
## Layout
### Spacing Tokens
- **Base**: `8px`
- **Xs**: `4px`
- **Sm**: `8px`
- **Md**: `16px`
- **Lg**: `24px`
- **Xl**: `32px`
- **2xl**: `48px`
- **3xl**: `64px`
- **4xl**: `96px`
### Grid
Desktop uses a 12-column asymmetrical grid: a fixed metadata rail plus flexible content columns. Key content spans 7–9 columns while summaries and controls occupy shorter bands. Tablet shifts to 8 columns with the metadata rail reduced; phone collapses to a single column with index markers becoming inline headers.
### Breakpoints
At 1024px reduce from 12 to 8 columns and tighten outer margins. At 768px stack the hero and operational panels vertically while preserving rule-based separators. At 480px convert all multi-column rows to a single column, make actions full-width, and allow tables to scroll horizontally inside ruled wrappers.
### Whitespace
Whitespace is structural: outer margins are large, inter-section spacing is 48–64px on desktop, and internal content uses an 8px baseline grid. Negative space should frame typography like poster composition rather than fill gaps evenly.
## Elevation & Depth
### Shadows
- **Sm**: 0 0 0 rgba(0,0,0,0)
- **Md**: 0 0 0 rgba(0,0,0,0)
- **Lg**: 0 0 0 rgba(0,0,0,0)
## Shapes
### Rounded
- **None**: `0px`
- **Sm**: `0px`
- **Md**: `0px`
- **Lg**: `0px`
- **Full**: `999px`
### Surfaces
- **Treatment**: paper
- **Card Style**: outlined planes with wide internal margins and hairline separators instead of elevation
- **Bg Pattern**: grid
### Borders
- **Default Width**: 1px
- **Accent Width**: 6px
- **Style**: solid
- **Character**: hairline and precise, used as structural dividers; accent bars are thick and vertical
## Components
### Composition
Build compositions on a disciplined modular grid with a persistent metadata rail at the left, content blocks spanning controlled column widths, and strong flush-left alignment. Major zones should be separated by open space and hairline rules rather than nested boxes.
### Hierarchy
Hierarchy comes from scale jumps, weight changes, red signal markers, and the position of content within the grid. Headlines are oversized and terse; supporting data is compact, uppercase, and mono or utility-sized.
### Density
Medium information density with high legibility: generous margins, compressed leading in headlines, and tightly ordered tables. No decorative padding inflation inside controls; whitespace should feel intentional and architectural.
### Signature Patterns
- every major section begins with a narrow red vertical bar anchored to the left grid edge
- module boundaries are drawn with 1px horizontal hairline rules instead of rounded cards or shadows
- section index numbers live in an oversized left rail and remain visually detached from the main content block
- all utility labels are uppercase with aggressive letter-spacing and aligned on a common baseline grid
- tables, forms, and tabs use monochrome fields with black underlines or perimeter rules rather than filled controls
## 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-019d9bb7-e627-7530-a101-1b84302c4aea/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 red sparingly as a positional signal, not as a general decorative fill.
- Do Keep all major text flush-left and let rag create the visual rhythm.
- Do Separate information blocks with rules and spacing instead of extra containers.
- Do Use tabular mono text for schedules, codes, and numeric summaries.
- Do Let typography carry emphasis before reaching for color or iconography.
- Don't Do not center headlines or balance pages symmetrically.
- Don't Do not introduce rounded corners, soft shadows, or glass effects.
- Don't Do not use multiple accent colors or illustrative gradients.
- Don't Do not wrap every region in thick boxes that destroy the open grid.
- Don't Do not make controls look tactile; they should feel engineered and flat.

# Swiss International Style shadcn/ui Components
Artifact: `component-recipes-v1`
Author: `katagami-ui-projection`
Language ID: `en-019d9bb7-e627-7530-a101-1b84302c4aea`
Slug: `swiss-international-style`
## Intent
Swiss International Style translates modernist clarity into interface systems: objective hierarchy, mathematical spacing, rigorous left alignment, and typography that behaves like an industrial standard rather than personal expression. The interface should feel like a timetable, poster grid, or transit information panel—lucid under pressure, spare without being empty, and persuasive through order rather than 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

Typography:

"mono_font": "IBM Plex Mono, monospace",
"base_size": "16px",

}
## Visual character to preserve
- strict asymmetric grid with an oversized left rail used for section indices and metadata
- hairline black rules separating modules, rows, and headings with no decorative framing
- large neo-grotesk headlines set flush-left with tight leading and generous negative space around them
- small uppercase utility labels tracked wide and aligned to a consistent baseline grid
- a limited white-black palette punctuated by one urgent signal red used as vertical bars, dots, and action accents

}
## 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-international-style/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 red sparingly as a positional signal, not as a general decorative fill.; Keep all major text flush-left and let rag create the visual rhythm.; Separate information blocks with rules and spacing instead of extra containers.; Use tabular mono text for schedules, codes, and numeric summaries.; Let typography carry emphasis before reaching for color or iconography.
- Do not: Do not center headlines or balance pages symmetrically.; Do not introduce rounded corners, soft shadows, or glass effects.; Do not use multiple accent colors or illustrative gradients.; Do not wrap every region in thick boxes that destroy the open grid.; Do not make controls look tactile; they should feel engineered and flat.
## 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": "Desktop uses a 12-column asymmetrical grid: a fixed metadata rail plus flexible content columns. Key content spans 7–9 columns while summaries and controls occupy shorter bands. Tablet shifts to 8 columns with the metadata rail reduced; phone collapses to a single column with index markers becoming inline headers.",
"breakpoints": "At 1024px reduce from 12 to 8 columns and tighten outer margins. At 768px stack the hero and operational panels vertically while preserving rule-based separators. At 480px convert all multi-column rows to a single column, make actions full-width, and allow tables to scroll horizontally inside ruled wrappers.",
"whitespace": "Whitespace is structural: outer margins are large, inter-section spacing is 48–64px on desktop, and internal content uses an 8px baseline grid. Negative space should frame typography like poster composition rather than fill gaps evenly."
