composition

Use a visible modular column system with uneven spans, letting one dominant content block lead while metadata and controls occupy narrow adjacent rails.

hierarchy
Create hierarchy through scale, weight, and alignment shifts; headlines are oversized and tightly set, while labels, timestamps, and captions use compact uppercase treatments.
density

Moderate to high density with intentional compression, avoiding roomy lifestyle-SaaS spacing while preserving enough breathing room for legibility.

signature patterns
Section headers are introduced by horizontal rule systems: a thin graphite line across the module with a short vermilion segment marking the left origin of the heading.Data cards use explicit row dividers and flush-left labels so content reads like editorial tables rather than rounded app widgets.Key metric figures and headlines are placed in oversized type that intentionally breaks expected component proportion, making typography itself the primary graphic device.Navigation and utility controls align to the same baseline grid as content, with uppercase tracking and mono metadata reinforcing a publication-like system.
layout
grid
Desktop uses a 12-column editorial grid with 24px gutters and frequent 3/5/7 column spans; tablet reduces to 8 columns and mobile collapses to a single stacked flow while preserving rule-based separators.
breakpoints

Desktop 1440 and above, tablet at 1024 and 768, mobile at 560 and 375 with all modules snapping to simplified column logic.

whitespace
Whitespace is structural and measured in grid increments; leave strong margins at the page edge but keep interior modules compact and rhythmically separated by rules, not floating gaps.
guidance
do
  • Use black typography as the default visual anchor on light fields.
  • Build sections from grids, rule lines, and baseline alignment before adding decorative accent.
  • Reserve vermilion for small directional moments like tabs, counts, origin marks, and action emphasis.
avoid
  • Do not introduce soft rounded cards or colorful gradient hero areas.
  • Do not center everything; asymmetry is part of the language structure.
  • Do not solve hierarchy with many accent colors when typography and grid can do the work.

# Swiss Editorial Grid Modernism

## Philosophy

A rigorously ordered interface language translating International Typographic Style into digital product surfaces through mathematically aligned columns, assertive sans serif typography, disciplined asymmetry, and an almost clinical reduction of decoration.

### Values

- objective communication over expressive ornament
- grid logic as the primary source of visual order
- high legibility through scale, alignment, and contrast

### Anti-Values

- soft decorative whimsy
- skeuomorphic texture and sentimental realism
- centered symmetry used without informational purpose

### Visual Character

- A strict multi-column grid governs every major region, with modules snapping to visible alignment lines so whitespace feels measured rather than casual or atmospheric.
- Large black grotesk headlines sit flush to the grid with tight line breaks, while small uppercase meta labels in mono or compact sans create editorial hierarchy through scale contrast rather than color abundance.
- Cards and panels use flat cool-white surfaces, hairline graphite rules, and occasional vermilion bars or dots as positional accents, never as full-surface fills or gradient decoration.
- Compositions favor asymmetry: oversized information blocks occupy wider spans while secondary data is stacked in narrow side columns, echoing poster and journal layouts from Swiss modernism.

# Swiss Editorial Grid Modernism

## Overview

A rigorously ordered interface language translating International Typographic Style into digital product surfaces through mathematically aligned columns, assertive sans serif typography, disciplined asymmetry, and an almost clinical reduction of decoration.

### Values

- objective communication over expressive ornament
- grid logic as the primary source of visual order
- high legibility through scale, alignment, and contrast

### Anti-Values

- soft decorative whimsy
- skeuomorphic texture and sentimental realism
- centered symmetry used without informational purpose

### Visual Character

- A strict multi-column grid governs every major region, with modules snapping to visible alignment lines so whitespace feels measured rather than casual or atmospheric.
- Large black grotesk headlines sit flush to the grid with tight line breaks, while small uppercase meta labels in mono or compact sans create editorial hierarchy through scale contrast rather than color abundance.
- Cards and panels use flat cool-white surfaces, hairline graphite rules, and occasional vermilion bars or dots as positional accents, never as full-surface fills or gradient decoration.
- Compositions favor asymmetry: oversized information blocks occupy wider spans while secondary data is stacked in narrow side columns, echoing poster and journal layouts from Swiss modernism.

## Components

### Composition

Use a visible modular column system with uneven spans, letting one dominant content block lead while metadata and controls occupy narrow adjacent rails.

### Hierarchy

Create hierarchy through scale, weight, and alignment shifts; headlines are oversized and tightly set, while labels, timestamps, and captions use compact uppercase treatments.

### Density

Moderate to high density with intentional compression, avoiding roomy lifestyle-SaaS spacing while preserving enough breathing room for legibility.

### Signature Patterns

- Section headers are introduced by horizontal rule systems: a thin graphite line across the module with a short vermilion segment marking the left origin of the heading.
- Data cards use explicit row dividers and flush-left labels so content reads like editorial tables rather than rounded app widgets.
- Key metric figures and headlines are placed in oversized type that intentionally breaks expected component proportion, making typography itself the primary graphic device.
- Navigation and utility controls align to the same baseline grid as content, with uppercase tracking and mono metadata reinforcing a publication-like system.

## 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-019da290-e813-7893-bafa-308e2a93668e/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 typography as the default visual anchor on light fields.
- Do Build sections from grids, rule lines, and baseline alignment before adding decorative accent.
- Do Reserve vermilion for small directional moments like tabs, counts, origin marks, and action emphasis.
- Don't Do not introduce soft rounded cards or colorful gradient hero areas.
- Don't Do not center everything; asymmetry is part of the language structure.
- Don't Do not solve hierarchy with many accent colors when typography and grid can do the work.

# Swiss Editorial Grid Modernism shadcn/ui Components

Artifact: `component-recipes-v1`
Author: `katagami-ui-projection`
Language ID: `en-019da290-e813-7893-bafa-308e2a93668e`
Slug: `swiss-editorial-grid-modernism`

## Intent

A rigorously ordered interface language translating International Typographic Style into digital product surfaces through mathematically aligned columns, assertive sans serif typography, disciplined asymmetry, and an almost clinical reduction of 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:

{
  "primary": "#111111",
  "secondary": "#58616A",
  "accent": "#C63A2B",
  "background": "#F4F4F0",
  "surface": "#FBFBF8",
  "text": "#111111",
  "muted": "#727A82",
  "border": "#A9AFB5",
  "error": "#B42318",
  "success": "#1F6B4F",
  "warning": "#A15C00",
  "info": "#245D8C"
}

Typography:

{
  "heading_font": "Space Grotesk",
  "body_font": "IBM Plex Sans",
  "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=IBM+Plex+Sans:wght@400;500;600;700&family=IBM+Plex+Mono:wght@400;500;600&family=Space+Grotesk:wght@500;700&display=swap"
}

## Visual character to preserve

- A strict multi-column grid governs every major region, with modules snapping to visible alignment lines so whitespace feels measured rather than casual or atmospheric.
- Large black grotesk headlines sit flush to the grid with tight line breaks, while small uppercase meta labels in mono or compact sans create editorial hierarchy through scale contrast rather than color abundance.
- Cards and panels use flat cool-white surfaces, hairline graphite rules, and occasional vermilion bars or dots as positional accents, never as full-surface fills or gradient decoration.
- Compositions favor asymmetry: oversized information blocks occupy wider spans while secondary data is stacked in narrow side columns, echoing poster and journal layouts from Swiss modernism.

## ShadSync visual profile

{
  "family": "paper-collage",
  "material": "paper",
  "contour": "default",
  "border": "solid",
  "underlay": false,
  "grain": true,
  "stickerBadges": false,
  "motion": "lift",
  "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/swiss-editorial-grid-modernism/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 typography as the default visual anchor on light fields.; Build sections from grids, rule lines, and baseline alignment before adding decorative accent.; Reserve vermilion for small directional moments like tabs, counts, origin marks, and action emphasis.
- Do not: Do not introduce soft rounded cards or colorful gradient hero areas.; Do not center everything; asymmetry is part of the language structure.; Do not solve hierarchy with many accent colors when typography and grid can do the work.

## 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 editorial grid with 24px gutters and frequent 3/5/7 column spans; tablet reduces to 8 columns and mobile collapses to a single stacked flow while preserving rule-based separators.",
  "breakpoints": "Desktop 1440 and above, tablet at 1024 and 768, mobile at 560 and 375 with all modules snapping to simplified column logic.",
  "whitespace": "Whitespace is structural and measured in grid increments; leave strong margins at the page edge but keep interior modules compact and rhythmically separated by rules, not floating gaps."
