# Silent Gantry Notation shadcn/ui Components

Artifact: `component-recipes-v1`
Author: `katagami-ui-projection`
Language ID: `en-019e07eb-20b2-7ba1-9e99-d97c57d1d6d9`
Slug: `silent-gantry-notation`

## Intent

Silent Gantry Notation is a restrained cockpit language for mission-critical machine proximity: black-and-white manga panel structure holds a distant mecha diagnostic frame, while pale HUD arcs and sparse amber callouts describe systems without turning the interface into spectacle. It treats the pilot screen as a place of quiet operational doubt, using absence, scale, and measured annotation to make the machine feel present but not anthropomorphic.

## 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`.

## Visual character to preserve

- Asymmetric manga-panel grid with thick black gutters, warm off-white data sheets, and one dominant matte graphite cockpit aperture.
- Thin pale blue-white HUD arcs built from CSS borders and pseudo-elements, never glowing more than a one-pixel technical overlay.
- Exploded mecha notation using dotted leader lines, small amber-orange numbered callouts, and separated graphite component silhouettes.
- Terminal fragments in compact monospace bands with Y2K serial labels, square LCD insets, and hardware tab captions.
- Large zones of deliberate empty black space around the machine diagram to express scale, silence, and human-machine distance.

  ]
}

## 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/silent-gantry-notation/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 thick black gutters to make manga structure visible before any UI details are noticed.; Keep HUD arcs one-pixel thin, pale, and clipped by the cockpit aperture.; Group cockpit controls into labeled operational clusters that reduce scan effort.; Use amber only for mechanical callout numbers, warnings, and leader endpoints.; Let off-white panels feel like printed technical sheets rather than glossy cards.; Include terminal text that reads like mission state, serial diagnostics, or calibration logs.; Preserve empty black space to communicate scale and quiet machine distance.
- Do not: Do not use green matrix rain, neon cyberpunk gradients, or saturated glow effects.; Do not fill the scene with generic dashboard widgets or SaaS metric cards.; Do not add anime characters, pilots, mascots, or heroic mecha poster poses.; Do not make HUD elements decorative if they do not support orientation or status.; Do not mix many accent colors; amber and pale blue-white are enough.; Do not round every surface; square hardware edges are the default.; Do not use unreadable fake microtext as texture.

## Copy-paste component example

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