rules
composition
Use large-format magazine spreads: an oversized left gutter, one dominant hero panel, secondary text columns, and deliberate black voids that separate reading zones.
hierarchy

Set primary headlines in dramatic serif sizes, pair them with uppercase monospace folios, and reserve body copy for narrow measure columns with high leading.

density

Keep density low to medium; clusters may be detailed, but every cluster needs adjacent empty near-black space.

signature patterns
Panels use ::before smoke veils made from blurred radial-gradients clipped inside sharp rectangular borders.Feature imagery uses CSS halftone dot overlays blended with grayscale gradients and low opacity fog masks.Section labels are uppercase monospace folios with thin horizontal rules extending across the available column.Primary cards carry a 3px vertical ink rule on the left plus a 1px pale hairline around the full rectangle.Large serif pull quotes overlap panel boundaries with mix-blend-mode screen and restrained negative letter spacing.
layout
grid

Desktop uses a 12-column editorial grid with a two-column left gutter reserved for folios and negative space.

breakpoints

mobile <= 640px, tablet 641px-1024px, desktop >= 1025px

whitespace

Whitespace is treated as black ink void: broad margins, 48-96px section gaps, and narrow body measures.

guidance
do
  • Use monochrome tonal contrast and smoke overlays to separate sections without bright color.
  • Pair oversized serif headlines with small uppercase monospace labels and measured sans body copy.
  • Keep edges sharp, borders hairline-thin, and important panels anchored by a dense vertical ink rule.
  • Let one large atmospheric image or quote dominate each screen before adding supporting modules.
avoid
  • Do not use saturated accent colors or friendly rounded SaaS cards.
  • Do not fill every grid column; preserve empty black fields as part of the composition.
  • Do not place smoke effects over long body copy when they reduce readability.
  • Do not use generic drop-shadow depth without grain, veil, or ink-rule structure.

# Atmospheric Noir Art Magazine

## Philosophy

A restrained black-monochrome editorial language for literary and fine-art interfaces, translating large-format magazine pacing, ink wash voids, and backlit smoke photography into a cinematic reading surface where atmosphere becomes structure rather than decoration.

### Values

- slow literary pacing with generous negative space
- ink as material gesture and typographic counterpoint
- fine-art restraint over feed-like density
- smoke and fog used as tonal depth fields
- high-contrast legibility against near-black surfaces

### Anti-Values

- bright commercial color systems
- generic card grids without atmospheric image treatment
- busy social-feed density
- decorative smoke that obscures reading
- rounded SaaS friendliness

### Visual Character

- Near-black page fields use layered radial smoke veils and subtle grain pseudo-elements behind content panels.
- Editorial cards are tall rectangular plates with hairline white borders and one heavy ink-black inner rule.
- Hero and feature images are monochrome halftone blocks masked by drifting fog gradients at the edges.
- Headlines use oversized high-contrast serif type with tight tracking beside small uppercase monospace folio labels.
- Layouts keep an oversized left gutter and asymmetrical columns so empty black space reads like an ink-wash void.

## 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/atmospheric-noir-art-magazine/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.

# Atmospheric Noir Art Magazine shadcn/ui Components

Artifact: `component-recipes-v1`
Author: `katagami-ui-projection`
Language ID: `atmospheric-noir-art-magazine`
Slug: `atmospheric-noir-art-magazine`

## Intent

A restrained black-monochrome editorial language for literary and fine-art interfaces, translating large-format magazine pacing, ink wash voids, and backlit smoke photography into a cinematic reading surface where atmosphere becomes structure 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

Colors:

{
  "primary": "#F4F1EA",
  "secondary": "#8B8D8F",
  "accent": "#D9D3C4",
  "background": "#050506",
  "surface": "#111113",
  "text": "#F7F5EF",
  "muted": "#9A9A96",
  "border": "#3B3B3D",
  "error": "#C96B63",
  "success": "#8FAF8A",
  "warning": "#C3A45D",
  "info": "#8AA7B8"
}

Typography:

{
  "heading_font": "Cormorant Garamond",
  "body_font": "Inter",
  "mono_font": "IBM Plex Mono",
  "base_size": "16px",
  "scale_ratio": 1.25,
  "line_height": 1.55,
  "letter_spacing": "-0.01em",
  "google_fonts_url": "https://fonts.googleapis.com/css2?family=Cormorant+Garamond:wght@500;600;700&family=IBM+Plex+Mono:wght@400;500;600&family=Inter:wght@400;500;600;700&display=swap"
}

## Visual character to preserve

- Near-black page fields use layered radial smoke veils and subtle grain pseudo-elements behind content panels.
- Editorial cards are tall rectangular plates with hairline white borders and one heavy ink-black inner rule.
- Hero and feature images are monochrome halftone blocks masked by drifting fog gradients at the edges.
- Headlines use oversized high-contrast serif type with tight tracking beside small uppercase monospace folio labels.
- Layouts keep an oversized left gutter and asymmetrical columns so empty black space reads like an ink-wash void.

## ShadSync visual profile

{
  "family": "paper-collage",
  "material": "paper",
  "contour": "default",
  "border": "solid",
  "underlay": true,
  "grain": true,
  "stickerBadges": false,
  "motion": "still",
  "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/atmospheric-noir-art-magazine/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 monochrome tonal contrast and smoke overlays to separate sections without bright color.; Pair oversized serif headlines with small uppercase monospace labels and measured sans body copy.; Keep edges sharp, borders hairline-thin, and important panels anchored by a dense vertical ink rule.; Let one large atmospheric image or quote dominate each screen before adding supporting modules.
- Do not: Do not use saturated accent colors or friendly rounded SaaS cards.; Do not fill every grid column; preserve empty black fields as part of the composition.; Do not place smoke effects over long body copy when they reduce readability.; Do not use generic drop-shadow depth without grain, veil, or ink-rule structure.

## Copy-paste component example

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