# Signal Ledger Spectrum shadcn/ui Components

Artifact: `component-recipes-v1`
Author: `katagami-ui-projection`
Language ID: `en-019ea9a3-d725-7ca2-a244-3df470fb362e`
Slug: `signal-ledger-spectrum`

## Intent

A dashboard-first enterprise language that separates neutral product chrome, semantic operational status, and analytical chart palettes so business data reads as trustworthy evidence 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:

{
  "accent": "#7C3AED",
  "background": "#F6F8FC",
  "border": "#D9E2EF",
  "error": "#B42318",
  "info": "#0B65C2",
  "muted": "#64748B",
  "primary": "#1D4ED8",
  "secondary": "#0F766E",
  "success": "#087443",
  "surface": "#FFFFFF",
  "text": "#172033",
  "warning": "#B54708"
}

Typography:

{
  "base_size": "16px",
  "body_font": "Source Sans 3",
  "google_fonts_url": "https://fonts.googleapis.com/css2?family=Sora:wght@500;600;700&family=Source+Sans+3:wght@400;500;600;700&family=IBM+Plex+Mono:wght@500;600&display=swap",
  "heading_font": "Sora",
  "letter_spacing": "-0.015em",
  "line_height": 1.52,
  "mono_font": "IBM Plex Mono",
  "scale_ratio": 1.2
}

## Visual character to preserve

- CSS custom properties split into --ui, --semantic, and --chart namespaces, with product chrome restricted to slate, blue, and low-chroma surfaces.
- Dashboard cards use quiet white panels, 1px cool-gray borders, and a left status rail so status remains visible independent of fill color.
- Charts combine solid categorical swatches with dot, stripe, and dash marker classes so series remain distinguishable when color perception or printing fails.
- Sequential data blocks use stepped blue-to-violet lightness ramps on pale grid backgrounds rather than rainbow hues, preserving readable labels and business seriousness.
- Critical semantic states pair color with icon geometry, badge text, and border pattern: check for success, triangle for warning, octagon for error, pulse ring for live info.

## ShadSync visual profile

{
  "family": "system",
  "material": "flat",
  "contour": "default",
  "border": "dashed",
  "underlay": false,
  "grain": false,
  "stickerBadges": true,
  "motion": "still",
  "density": "balanced",
  "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/signal-ledger-spectrum/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: Separate UI chrome colors from semantic status colors and from chart scales in names, legends, and CSS variables.; Pair every red, amber, green, or blue state with text, icon geometry, and border or pattern reinforcement.; Use categorical palettes for peers, sequential ramps for magnitude, and diverging scales only when a meaningful midpoint exists.; Keep dashboard backgrounds pale and low contrast so chart colors retain authority.
- Do not: Do not use rainbow scales for business metrics or mix semantic red/green into categorical chart series without explicit status meaning.; Do not place saturated violet, teal, and blue gradients behind small text or table values.; Do not rely on color alone for alerts, row health, chart series, or selected filters.; Do not let decorative brand color override contrast requirements for controls and focus states.

## Copy-paste component example

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