# Subway Ghost Packet Monitor shadcn/ui Components

Artifact: `component-recipes-v1`
Author: `katagami-ui-projection`
Language ID: `subway-ghost-packet-monitor`
Slug: `subway-ghost-packet-monitor`

## Intent

A ceramic-white network control language where subway wayfinding geometry behaves like packet telemetry and the most important presence is the station that is missing.

## 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": "#9D1D18",
  "background": "#F5F1E8",
  "border": "#D4CEC1",
  "error": "#9D1D18",
  "info": "#6E6A5B",
  "muted": "#77776F",
  "primary": "#0B0B09",
  "secondary": "#6F746F",
  "success": "#4F5B50",
  "surface": "#FFFDF6",
  "text": "#11110F",
  "warning": "#A0792B"
}

Typography:

{
  "base_size": "16px",
  "body_font": "Fragment Mono",
  "google_fonts_url": "https://fonts.googleapis.com/css2?family=Fragment+Mono&family=Geo&family=Saira+Condensed:wght@400;600;700&display=swap",
  "heading_font": "Saira Condensed",
  "letter_spacing": "-0.02em",
  "line_height": 1.5,
  "mono_font": "Geo",
  "scale_ratio": 1.22
}

## Visual character to preserve

- A ceramic tile background built from off-white fields and one-pixel grout grid lines that continues through panels instead of stopping at cards.
- Route-map packet paths drawn as thick orthogonal black SVG strokes with circular station ticks, transfer knots, and intentional missing stops.
- Dim red service pips appear only on interruption nodes and timestamp ledgers, capped as tiny circular event lights rather than broad accents.
- Black manga speed-line interference slices across tunnel bands using repeating linear gradients and clipped pseudo-elements at abrupt angles.
- Terminal telemetry sits in marginal station annotations with monospaced labels, bitmap numerals, cursor blocks, and delayed ping columns.

## ShadSync visual profile

{
  "family": "brutalist",
  "material": "ink",
  "contour": "default",
  "border": "dashed",
  "underlay": false,
  "grain": false,
  "stickerBadges": true,
  "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/subway-ghost-packet-monitor/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 orthogonal transit lines and station ticks as the primary interface structure.; Keep red rare, dim, and tied to faults, delayed pings, or service interruption nodes.; Allow blank tile fields and ghost gaps to carry narrative tension.; Crop panels abruptly so the screen feels like a live control wall larger than the viewport.
- Do not: Do not use neon cyan, green matrix rain, holograms, or cyberpunk glow.; Do not add character art, anime portraits, SaaS card grids, or rounded startup dashboards.; Do not smooth every motion; relay changes should tick or blink in discrete steps.; Do not make red a brand wash; it must stay under eight percent of the composition.

## Copy-paste component example

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