## Philosophy

A Swiss typographic monochrome press desk for the screen: warm press-paper ground, pure black ink, a halftone register rail as the signature mechanic, oversized grotesk headlines, structural rule lines, and one register vermilion used like a registration mark instead of decoration.

### Values

- clarity through typographic structure and rule lines rather than ornamental interface chrome
- asymmetric editorial grid logic that creates tension while preserving order and scanability
- near-monochrome restraint where ink, scale, the halftone screen and one register mark do the expressive work

### Anti-Values

- colourful accent washes, soft shadows, glass, or gradients other than the halftone dot raster
- rounded consumer-app styling, nested cards, or a single coloured accent edge pinned to a panel

## Rules

### Composition

Compose screens like a Swiss press sheet merged with a data ledger: one commanding headline zone, a narrow halftone register rail, and modular content slices locked to a visible column rhythm.

### Hierarchy

Use scale contrast first, then weight, then rule lines and the halftone screen, then a single vermilion register mark for the focal state. Headlines command, mono index labels stay quiet, data values are precise and sharply aligned.

### Density

Medium-high density with disciplined whitespace: content is plentiful but every cluster lives inside a measured grid with breathing room around major headlines.

### Signature

The halftone register rail — a numbered monospace index column with a dot-screen tick and a vertical rule that survives all breakpoints, with the same halftone raster recurring on stat underbars, chart bars and proof textures.

## Layout

### Grid

A two-track editorial grid (narrow index rail + wide content span) on minmax(0,1fr) columns with min-width:0 children; collapses to a single stacked column with the index rail as a horizontal band on mobile.

### Whitespace

Generous page margins and deliberate vertical rhythm, with compressed spacing inside data clusters so the contrast between macro-space and micro-density stays visible.

### Density

balanced

### Responsive

Renders from ~390px mobile to 2560px+ ultra-wide; single-column stack on mobile with non-essential nav hidden and no horizontal overflow; capped centred content on ultra-wide with only the hero spanning 100vw.

### Breakpoints

- **Mobile**: 390-767
- **Tablet**: 768-1439
- **Desktop**: 1440+

## Guidance

### Do

- Use black rule lines, scale contrast, alignment and the halftone screen as the primary expressive tools.
- Keep components rectangular, flat and grid-locked with visible structural seams; seat panels on a 2px black top rule.
- Reserve vermilion for the registration mark and focal states; set index labels, slugs, counts and times in IBM Plex Mono uppercase.

### Don't

- Introduce colourful accent washes, soft shadows, glass, or gradients other than the halftone dot raster.
- Pin a single coloured accent edge to a card, nest cards, box the nav into a floating pill, or round corners.
- Centre body content; preserve asymmetric tension and a left-anchored reading flow.

### Accessibility

High contrast throughout (ink #0E0E0C on paper #F4F3EE, white on ink); body text 17px+, table rows 14.5px+; every form control explicitly styled with a visible vermilion focus ring and an error-red invalid state; motion respects prefers-reduced-motion.

## Imagery Direction

### Pairs With

rasterwerk

### Summary

High-contrast monochrome lithographic halftone dot-screen imagery: any subject rendered in pure black ink on a bright field, every tone built from a mechanical dot raster, crossed by thin hairline registration rules and crop ticks aligned to a Swiss editorial grid.

### Subjects

- letterpress and offset printing machinery
- press cylinders and inked rollers
- architectural Swiss-modern concrete and steel
- objective still-life of tools and type

### Usage

One full-bleed halftone hero behind a solid white type plate on the landing; smaller halftone proofs and the dot-screen raster as the recurring interface texture on stat bars, chart bars and index ticks. End prompts with NO text, NO letters, NO logos.

## 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-019ef8e7-e881-7ea2-9b64-0ab97fedcfcc/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 rule lines, scale contrast, alignment and the halftone screen as the primary expressive tools.
- Do Keep components rectangular, flat and grid-locked with visible structural seams; seat panels on a 2px black top rule.
- Do Reserve vermilion for the registration mark and focal states; set index labels, slugs, counts and times in IBM Plex Mono uppercase.
- Don't Introduce colourful accent washes, soft shadows, glass, or gradients other than the halftone dot raster.
- Don't Pin a single coloured accent edge to a card, nest cards, box the nav into a floating pill, or round corners.
- Don't Centre body content; preserve asymmetric tension and a left-anchored reading flow.

### Accessibility

High contrast throughout (ink #0E0E0C on paper #F4F3EE, white on ink); body text 17px+, table rows 14.5px+; every form control explicitly styled with a visible vermilion focus ring and an error-red invalid state; motion respects prefers-reduced-motion.
