rules
Use a persistent shell: slim command rail, horizontal masthead, dominant editorial work area, and a narrower marginal column. Avoid equal modules; one table or chart must be visually dominant while smaller notes align to its baseline grid. Use rule lines as architecture and allow one grid break through an oversized headline or wide chart spanning columns.
Medium-high information density is acceptable when baselines are disciplined; rows use 44px minimum height, compact captions, and explicit separators so the interface feels operational rather than crowded.
Start with serif display for the screen title, then condensed uppercase Saira labels for navigation and filters, then tabular Azeret Mono for values. The active item is shown by position, rule weight, and cyan line rather than a filled pill. Secondary metadata stays muted but must remain readable on paper.
layout
1440px desktop multi-column shell; 768px tablet collapses the marginal column below the chart; 375px mobile converts rail to top tabs and stacks all sections.
Designed for dense operational review with clear row rhythm, generous outer margins, and compact but touch-safe controls.
Desktop uses a 72px rail plus a 12-column content grid with 24px gutters and a 320px marginal column inside a max-width-free app shell.
At tablet widths, shell columns become a two-row composition; at mobile widths, controls wrap, charts simplify, and minimum tap targets remain at least 44px.
Whitespace appears as gutters and editorial pauses around headings, not as padded cards; dense tables are balanced by one open masthead area.
guidance
- Use paper, charcoal, taupe rules, cyan action marks, and rare amber warnings as the complete palette for product screens.
- Make at least one data surface dominant, preferably a ledger table or chart that spans more columns than supporting modules.
- Set numbers in Azeret Mono with tabular alignment and keep status language textual, never dependent on color alone.
- Use square or nearly square corners, flat surfaces, and visible dividers before considering elevation.
- Keep cyan below roughly five percent of the screen area and attach it to active or live states only.
- Provide keyboard focus as a 2px cyan outline with offset or an accent-width rule paired with text state.
- Do not use gradient backgrounds, glowing pills, pulsing dots, emoji, unrelated icon tiles, or generic SaaS hero ornaments.
- Do not create three equal rounded stat cards; vary module scale and let rules rather than cards define structure.
- Do not introduce extra brand colors, rainbow charts, or decorative illustrations that weaken token discipline.
- Do not hide hierarchy behind low-contrast gray text; muted copy must pass accessible contrast on paper surfaces.
- Do not use oversized ultra-bold headings or tight-tracked marketing slogans; titles should feel editorial and precise.
- Do not round every control into pills; tabs, filters, and buttons should look rule-joined and system-native.

# Ledger Paper Command Shell ## Philosophy Ledger Paper Command Shell is an editorial data-app language for operational software that needs to feel authored, sober, and production-ready. It borrows from newspaper ledgers, trading-room work surfaces, and modern command centers: warm paper, charcoal type, rule-line structure, and one high-chroma cyan used only where data or action must pierce the page. ### Values - Content-first authority: tables, captions, filters, and charts are given typographic hierarchy before decorative surface treatment. - Governed color: neutral paper and ink do nearly all of the work; cyan is reserved for active data, primary action, and live cursor states. - Editorial asymmetry: screens use offset columns, marginal metadata, and dominant modules instead of equal card grids. - Production credibility: every element resembles a real app control, report artifact, chart, log, or operational decision point. - Accessible restraint: contrast, target size, focus state, and semantic color roles are explicit so the system can scale across teams. ### Anti-Values - Generic SaaS optimism, oversized rounded cards, gradient keyword emphasis, and decorative icon bento layouts. - Uncontrolled accent use, rainbow charts, or color-only status systems that break role-based token discipline. - Sterile blankness: minimalism must still carry texture through typography, rules, density, and meaningful data. ### Visual Character - Use a full-height app shell divided by 1px charcoal rule lines, including a narrow left rail, a masthead strip, and an offset marginal notes column. - Render major modules as paper sections with square corners, no decorative cards, and internal ledger rules created by border-bottom and repeating-linear-gradient rows. - Create hierarchy through a serif editorial headline, condensed uppercase sans labels, tabular numeric mono data, and visibly different tracking values. - Reserve the cyan accent for a thin left selection rail, chart strokes, active filter underlines, focus outlines, and one primary command button only. - Build dense data areas with aligned baselines, vertical dividers, inline status words, and sparse amber warning marks instead of icons or badges. ## Tokens ### Borders - **Accent Width**: 3px - **Character**: Hairline charcoal and taupe rules form the application architecture; accent borders appear only on active selection and focus. - **Default Width**: 1px - **Style**: solid ### Colors | Name | Value | |------|-------| | accent | `#00A7C8` | | background | `#F4F0E8` | | border | `#C9C0B4` | | error | `#B3261E` | | info | `#006C84` | | muted | `#6E675E` | | primary | `#111111` | | secondary | `#3A352F` | | success | `#247A4D` | | surface | `#FFFCF5` | | text | `#151515` | | warning | `#B46A00` | ### Motion - **Duration**: 140ms - **Easing**: cubic-bezier(.2,.8,.2,1) - **Philosophy**: Motion is utilitarian: fast underline shifts, focus ring appearance, and row reveal states; no bounce, pulse, or decorative animation. ### Radii - **Full**: 9999px - **Lg**: 6px - **Md**: 4px - **None**: 0 - **Sm**: 2px ### Shadows - **Lg**: 0 18px 60px rgba(21,21,21,0.10) - **Md**: 0 1px 0 rgba(17,17,17,0.08) - **Sm**: none ### Spacing - **Base**: 8px - **Scale**: [4,8,12,16,24,32,40,48,64,80] ### Surfaces - **Bg Pattern**: A very faint horizontal ledger rhythm using repeating-linear-gradient at 32px intervals over the paper background. - **Card Style**: Sections are flat paper slabs bounded by 1px rules; grouping comes from headers, ledgers, and dividers rather than nested cards. - **Treatment**: Warm paper ground with charcoal ink, square section boundaries, and no ornamental gradients. ### Typography - **Base Size**: 16px - **Body Font**: Saira - **Google Fonts Url**: https://fonts.googleapis.com/css2?family=Azeret+Mono:wght@400;500;600&family=Libre+Baskerville:wght@400;700&family=Saira:ital,wght@0,400;0,500;0,600;0,700;1,400&display=swap - **Heading Font**: Libre Baskerville - **Letter Spacing**: -0.018em - **Line Height**: 1.52 - **Mono Font**: Azeret Mono - **Scale Ratio**: 1.22 ## Rules ### Composition Use a persistent shell: slim command rail, horizontal masthead, dominant editorial work area, and a narrower marginal column.

# Ledger Paper Command Shell
## Overview
Ledger Paper Command Shell is an editorial data-app language for operational software that needs to feel authored, sober, and production-ready. It borrows from newspaper ledgers, trading-room work surfaces, and modern command centers: warm paper, charcoal type, rule-line structure, and one high-chroma cyan used only where data or action must pierce the page.
### Values
- Content-first authority: tables, captions, filters, and charts are given typographic hierarchy before decorative surface treatment.
- Governed color: neutral paper and ink do nearly all of the work; cyan is reserved for active data, primary action, and live cursor states.
- Editorial asymmetry: screens use offset columns, marginal metadata, and dominant modules instead of equal card grids.
- Production credibility: every element resembles a real app control, report artifact, chart, log, or operational decision point.
- Accessible restraint: contrast, target size, focus state, and semantic color roles are explicit so the system can scale across teams.
### Anti-Values
- Generic SaaS optimism, oversized rounded cards, gradient keyword emphasis, and decorative icon bento layouts.
- Uncontrolled accent use, rainbow charts, or color-only status systems that break role-based token discipline.
- Sterile blankness: minimalism must still carry texture through typography, rules, density, and meaningful data.
### Visual Character
- Use a full-height app shell divided by 1px charcoal rule lines, including a narrow left rail, a masthead strip, and an offset marginal notes column.
- Render major modules as paper sections with square corners, no decorative cards, and internal ledger rules created by border-bottom and repeating-linear-gradient rows.
- Create hierarchy through a serif editorial headline, condensed uppercase sans labels, tabular numeric mono data, and visibly different tracking values.
- Reserve the cyan accent for a thin left selection rail, chart strokes, active filter underlines, focus outlines, and one primary command button only.
- Build dense data areas with aligned baselines, vertical dividers, inline status words, and sparse amber warning marks instead of icons or badges.
## Colors
Use the YAML color tokens as the normative palette. The prose below names the roles agents should preserve when generating UI.
| Token | Value |
|-------|-------|
| accent | `#00A7C8` |
| background | `#F4F0E8` |
| border | `#C9C0B4` |
| error | `#B3261E` |
| info | `#006C84` |
| muted | `#6E675E` |
| primary | `#111111` |
| secondary | `#3A352F` |
| success | `#247A4D` |
| surface | `#FFFCF5` |
| text | `#151515` |
| warning | `#B46A00` |

### Density
Designed for dense operational review with clear row rhythm, generous outer margins, and compact but touch-safe controls.
### Grid
Desktop uses a 72px rail plus a 12-column content grid with 24px gutters and a 320px marginal column inside a max-width-free app shell.
### Responsive
At tablet widths, shell columns become a two-row composition; at mobile widths, controls wrap, charts simplify, and minimum tap targets remain at least 44px.
### Whitespace
Whitespace appears as gutters and editorial pauses around headings, not as padded cards; dense tables are balanced by one open masthead area.

### Surfaces
- **Bg Pattern**: A very faint horizontal ledger rhythm using repeating-linear-gradient at 32px intervals over the paper background.
- **Card Style**: Sections are flat paper slabs bounded by 1px rules; grouping comes from headers, ledgers, and dividers rather than nested cards.
- **Treatment**: Warm paper ground with charcoal ink, square section boundaries, and no ornamental gradients.
### Borders
- **Accent Width**: 3px
- **Character**: Hairline charcoal and taupe rules form the application architecture; accent borders appear only on active selection and focus.
- **Default Width**: 1px
- **Style**: solid
## Components
### Composition
Use a persistent shell: slim command rail, horizontal masthead, dominant editorial work area, and a narrower marginal column. Avoid equal modules; one table or chart must be visually dominant while smaller notes align to its baseline grid. Use rule lines as architecture and allow one grid break through an oversized headline or wide chart spanning columns.
### Density
Medium-high information density is acceptable when baselines are disciplined; rows use 44px minimum height, compact captions, and explicit separators so the interface feels operational rather than crowded.
### Hierarchy
Start with serif display for the screen title, then condensed uppercase Saira labels for navigation and filters, then tabular Azeret Mono for values. The active item is shown by position, rule weight, and cyan line rather than a filled pill. Secondary metadata stays muted but must remain readable on paper.
### Signature Patterns
- Ledger row rhythm: repeating-linear-gradient and border-bottom combine to create subtle accounting-paper bands behind tables and activity logs.
- Cyan command rail: a 3px vertical or horizontal accent line marks active navigation, selected rows, chart traces, and focus states with one governed token.
- Editorial marginalia column: a narrower right column carries timestamped notes, exceptions, and source labels separated by rule lines, not cards.
- Rule-joined controls: filters, tabs, and buttons share square edges and underline states so controls feel typeset into the shell rather than floating.
## shadcn/ui Usage
When the target app uses shadcn/ui, copy DESIGN.md with shadcn instead of the plain DESIGN.md. It contains the same Katagami design-language source plus the shadcn/ui primitives, imports, theme variables, component recipes, and preview-shot guidance.
DESIGN.md with shadcn: `/language/ledger-paper-command-shell/DESIGN.with-shadcn.md`.
The shadcn page also exposes optional machine-readable files for automation, but the human-facing handoff is DESIGN.md with shadcn.
Install recommended primitives with `npx shadcn@latest add button card input textarea select dialog sheet tabs badge separator checkbox switch slider tooltip dropdown-menu table`.
Use these primitives in shadcn apps:
- button
- card
- input
- textarea
- select
- dialog
- sheet
- tabs
- badge
- separator
- checkbox
- switch
- slider
- tooltip
- dropdown-menu
- table
Implementation rule for agents: import shadcn primitives from `@/components/ui/*`, apply the generated CSS variables first, then compose the language-specific recipes from the companion MD. Katagami remains the source of truth; shadcn names are the implementation surface.
## Do's and Don'ts
- Do Use paper, charcoal, taupe rules, cyan action marks, and rare amber warnings as the complete palette for product screens.
- Do Make at least one data surface dominant, preferably a ledger table or chart that spans more columns than supporting modules.
- Do Set numbers in Azeret Mono with tabular alignment and keep status language textual, never dependent on color alone.
- Do Use square or nearly square corners, flat surfaces, and visible dividers before considering elevation.
- Do Keep cyan below roughly five percent of the screen area and attach it to active or live states only.
- Do Provide keyboard focus as a 2px cyan outline with offset or an accent-width rule paired with text state.
- Don't Do not use gradient backgrounds, glowing pills, pulsing dots, emoji, unrelated icon tiles, or generic SaaS hero ornaments.
- Don't Do not create three equal rounded stat cards; vary module scale and let rules rather than cards define structure.
- Don't Do not introduce extra brand colors, rainbow charts, or decorative illustrations that weaken token discipline.
- Don't Do not hide hierarchy behind low-contrast gray text; muted copy must pass accessible contrast on paper surfaces.
- Don't Do not use oversized ultra-bold headings or tight-tracked marketing slogans; titles should feel editorial and precise.
- Don't Do not round every control into pills; tabs, filters, and buttons should look rule-joined and system-native.
### Accessibility
Maintain WCAG AA contrast on all paper surfaces; pair warning and success colors with labels or rule patterns; keep body text at 16px, row heights near 44px, and focus outlines visible against both paper and charcoal.
### Usage Context
Best for editorial dashboards, risk consoles, analytics workspaces, audit products, developer operations, and internal tools that require trust under density.

# Ledger Paper Command Shell shadcn/ui Components
Artifact: `component-recipes-v1`
Author: `katagami-ui-projection`
Language ID: `ledger-paper-command-shell`
Slug: `ledger-paper-command-shell`
## Intent
Ledger Paper Command Shell is an editorial data-app language for operational software that needs to feel authored, sober, and production-ready. It borrows from newspaper ledgers, trading-room work surfaces, and modern command centers: warm paper, charcoal type, rule-line structure, and one high-chroma cyan used only where data or action must pierce the page.
## 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

}
## Visual character to preserve
- Use a full-height app shell divided by 1px charcoal rule lines, including a narrow left rail, a masthead strip, and an offset marginal notes column.
- Render major modules as paper sections with square corners, no decorative cards, and internal ledger rules created by border-bottom and repeating-linear-gradient rows.
- Create hierarchy through a serif editorial headline, condensed uppercase sans labels, tabular numeric mono data, and visibly different tracking values.
- Reserve the cyan accent for a thin left selection rail, chart strokes, active filter underlines, focus outlines, and one primary command button only.
- Build dense data areas with aligned baselines, vertical dividers, inline status words, and sparse amber warning marks instead of icons or badges.

}
## 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/ledger-paper-command-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: Use paper, charcoal, taupe rules, cyan action marks, and rare amber warnings as the complete palette for product screens.; Make at least one data surface dominant, preferably a ledger table or chart that spans more columns than supporting modules.; Set numbers in Azeret Mono with tabular alignment and keep status language textual, never dependent on color alone.; Use square or nearly square corners, flat surfaces, and visible dividers before considering elevation.; Keep cyan below roughly five percent of the screen area and attach it to active or live states only.; Provide keyboard focus as a 2px cyan outline with offset or an accent-width rule paired with text state.
- Do not: Do not use gradient backgrounds, glowing pills, pulsing dots, emoji, unrelated icon tiles, or generic SaaS hero ornaments.; Do not create three equal rounded stat cards; vary module scale and let rules rather than cards define structure.; Do not introduce extra brand colors, rainbow charts, or decorative illustrations that weaken token discipline.; Do not hide hierarchy behind low-contrast gray text; muted copy must pass accessible contrast on paper surfaces.; Do not use oversized ultra-bold headings or tight-tracked marketing slogans; titles should feel editorial and precise.; Do not round every control into pills; tabs, filters, and buttons should look rule-joined and system-native.

## Layout notes
{
"breakpoints": "1440px desktop multi-column shell; 768px tablet collapses the marginal column below the chart; 375px mobile converts rail to top tabs and stacks all sections.",
"density": "Designed for dense operational review with clear row rhythm, generous outer margins, and compact but touch-safe controls.",
"grid": "Desktop uses a 72px rail plus a 12-column content grid with 24px gutters and a 320px marginal column inside a max-width-free app shell.",
"responsive": "At tablet widths, shell columns become a two-row composition; at mobile widths, controls wrap, charts simplify, and minimum tap targets remain at least 44px.",
"whitespace": "Whitespace appears as gutters and editorial pauses around headings, not as padded cards; dense tables are balanced by one open masthead area."
