# Null Koma Terminal Noir shadcn/ui Components

Artifact: `component-recipes-v1`
Author: `katagami-ui-projection`
Language ID: `null-koma-terminal-noir`
Slug: `null-koma-terminal-noir`

## Intent

Null Koma Terminal Noir is a polished monochrome interface language for systems that feel observed rather than operated: manga panel grammar, command-line evidence, and cyberpunk calm reduced to black ink, paper white, grayscale wash, and a single rare phosphor signal.

## 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:

{
  "accent": "#7CFF9A",
  "background": "#FFFFFF",
  "border": "#050505",
  "error": "#B3261E",
  "info": "#4B6470",
  "muted": "#6E6E68",
  "primary": "#050505",
  "secondary": "#FFFFFF",
  "success": "#2F7D4A",
  "surface": "#F5F5F2",
  "text": "#050505",
  "warning": "#9A6A10"
}

Typography:

{
  "base_size": "16px",
  "body_font": "Noto Sans",
  "display_letter_spacing": "-0.035em",
  "display_line_height": "1.08",
  "google_fonts_url": "https://fonts.googleapis.com/css2?family=Kode+Mono:wght@400;500;600;700&family=Noto+Sans:wght@400;500;600;700&family=Teko:wght@500;600;700&display=swap",
  "heading_font": "Teko",
  "label_letter_spacing": "0.08em",
  "letter_spacing": "-0.02em",
  "line_height": 1.56,
  "mono_font": "Kode Mono",
  "scale_ratio": 1.24
}

## Visual character to preserve

- Use square black koma panels with 2px outer rules, 1px interior diagnostic frames, and cinematic gutters that become the primary layout grid.
- Place a vertical condensed title rail on one edge with writing-mode vertical-rl, stacked section codes, and rotated timestamps for anime-title tension.
- Render command output blocks as white-on-black terminal slabs with prompt cursors, shell paths, monospace tabular numerals, and clipped corner labels.
- Build grayscale ink atmosphere through halftone radial masks, scanline dividers, and wash overlays at very low opacity, never through color gradients.
- Reserve #7CFF9A phosphor green for live cursors, focus rings, one diagnostic state, and no more than a few tiny existential signal moments.

## ShadSync visual profile

{
  "family": "paper-collage",
  "material": "paper",
  "contour": "default",
  "border": "solid",
  "underlay": false,
  "grain": true,
  "stickerBadges": true,
  "motion": "lift-rotate",
  "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/null-koma-terminal-noir/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, white, and grayscale as the real palette; introduce phosphor green only for live machine signal or focus.; Make manga panel borders, gutters, and cropped frames the layout structure instead of adding decorative illustrations.; Write real interface language: shell paths, timestamps, error codes, diagnostic labels, and command output with tabular alignment.; Keep corners square except rare 16px containment for a viewport or device shell that needs separation.; Vary scale aggressively: one dominant panel, one dense slab, one quiet void, and at least one vertical or rotated text moment.; Apply -0.02em tracking to body text and tighter display tracking so the austerity feels polished rather than default.; Use halftone and scanline textures below legibility thresholds and away from long body text.; Pair any color-coded status with text, border weight, or a symbol so the accent is not the only cue.
- Do not: Do not use character art, anime eyes, mecha silhouettes, city neon, or other literal cosplay references.; Do not build three equal analytics cards or a generic SaaS dashboard scene.; Do not add glow, multi-color gradients, chromatic aberration, or rainbow hacker terminal palettes.; Do not soften the language with large rounded cards, blue CTAs, or friendly product illustration.; Do not cover small text with scanlines, halftone dots, or low-contrast gray overlays.; Do not use the accent for decoration, icons in bulk, section backgrounds, or brand color flooding.; Do not center every section; asymmetry and gutters must carry the manga spread rhythm.; Do not let micrographics become clutter; every cursor, path, and code must imply function.

## 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

{
  "breakpoints": "Mobile below 640px stacks panels while preserving title rail as a top code strip; tablet 640-1024px uses two columns; desktop above 1024px restores asymmetric spread composition.",
  "density": "Medium-low overall density with deliberate pockets of terminal compression; the system should feel quiet, not empty.",
  "grid": "Desktop uses a 12-column spread with 24px gutters and a max-width near 1320px; panels span uneven widths, including one 7-column dominant frame and one narrow vertical rail.",
  "whitespace": "Whitespace is cinematic and asymmetric: preserve 64px to 128px paper fields around key panels, while prompts and metadata cluster at 4px to 12px."
