# Ledgerline Paper Shell shadcn/ui Components

Artifact: `component-recipes-v1`
Author: `katagami-ui-projection`
Language ID: `ledgerline-paper-shell`
Slug: `ledgerline-paper-shell`

## Intent

Ledgerline Paper Shell is a restrained application language for editorial operations products that need the calm of a printed production ledger and the speed of modern SaaS. It uses warm paper, exacting dark typography, quiet rules, modular panels, and a single fresh chartreuse accent to make selected navigation, live work, and critical metrics unmistakable without turning the interface into a colorful dashboard.

## 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": "#B7DC35",
  "background": "#F6F1E8",
  "border": "#181612",
  "error": "#B44B3F",
  "info": "#3F6593",
  "muted": "#746C60",
  "primary": "#191715",
  "secondary": "#5F584E",
  "success": "#567A35",
  "surface": "#FFFCF4",
  "text": "#191715",
  "warning": "#A36D1D"
}

Typography:

{
  "base_size": "16px",
  "body_font": "Source Sans 3",
  "display_letter_spacing": "-0.04em",
  "google_fonts_url": "https://fonts.googleapis.com/css2?family=Azeret+Mono:wght@500;650&family=Fraunces:opsz,wght,SOFT,WONK@9..144,650..800,20,0&family=Source+Sans+3:wght@400;520;650;750&display=swap",
  "heading_font": "Fraunces",
  "letter_spacing": "-0.02em",
  "line_height": 1.55,
  "mono_font": "Azeret Mono",
  "scale_ratio": 1.25
}

## Visual character to preserve

- A fixed paper app shell uses an off-white body, a slightly warmer left rail, and crisp dark type with rgba(24,22,18,.08) hairline dividers between major regions.
- Panels use modular ledger cards with 24px radius, 1px near-invisible borders, a small uppercase folio label, and an inset top rule instead of heavy shadows.
- The selected navigation item and live metrics are marked by a narrow chartreuse vertical tab plus bold dark text, never by filled colorful pills across the whole row.
- Dense production rows use alternating paper tints, mono time stamps, small status chips, and vertical separator rules to create dashboard structure without charts dominating.
- One large asymmetric editorial workspace occupies roughly half the desktop grid while compact right-side modules stack as quiet reference panels.

## ShadSync visual profile

{
  "family": "paper-collage",
  "material": "paper",
  "contour": "pebble",
  "border": "solid",
  "underlay": false,
  "grain": true,
  "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/ledgerline-paper-shell/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: Start with warm paper neutrals and dark typography; add accent only after hierarchy works without it.; Use the chartreuse accent for selected navigation, live state, focus rings, and one key metric per screen.; Keep borders as rgba hairlines and use spacing or type weight before adding shadows.; Make at least one panel visually dominant through scale, not through color.; Include mono folio labels, timestamps, or IDs wherever a panel represents operational status.; Pair every semantic color with text, icon shape, or border weight for accessibility.; Use -0.02em tracking globally and -0.04em on display headings.
- Do not: Do not add multicolor charts, decorative gradients, or rainbow status systems.; Do not make three equal cards in a row; vary scale and density.; Do not fill selected navigation with a bright rectangle; use the narrow tab signature.; Do not use low contrast muted text for essential labels or values.; Do not round components with arbitrary radii outside the 0/16/24/9999 scale.; Do not let paper texture interfere with legibility or focus visibility.; Do not communicate live, error, or success state by color alone.

## 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 720px collapses the rail into a horizontal strip and stacks panels; tablet uses a two-column grid with the priority queue full width.",
  "density": "Compact editorial operations density with 16px body text, 24px card padding, 4-12px metadata clusters, and generous 64-96px gaps around primary groups.",
  "grid": "Desktop uses 88px rail plus 12-column content grid with 24px gutters and max-width 1440px; the hero work panel spans 7 columns while the right stack spans 4.",
  "responsive": "At narrow widths, keep the chartreuse active tab as a top border, preserve touch targets above 44px, and collapse nonessential metadata into concise rows.",
  "whitespace": "Whitespace is uneven by design: dense rows inside panels, 32px between sibling modules, and 64px around the primary workspace to avoid uniform SaaS spacing."
