guidance
do
  • Use cyan for live comparison, selected states, and primary analytical insight.
  • Use copper sparingly for thresholds, confidence checks, warnings, and human approvals.
  • Let slate tonal variation carry most chart and table structure.
  • Keep white backgrounds clean, untextured, and free of dots or square grids.
avoid
  • Do not use rainbow charts, multicolor KPI cards, confetti, or arbitrary extra vivid hues.
  • Do not add colored side rails, decorative stripes, or accent borders on cards and rows.
  • Do not use generic dashboard widgets without a believable product decision scene.
  • Do not place dotted notebook, point-grid, square-grid, or graph-paper backgrounds behind the UI.

# Aperture Ledger

## Philosophy

Aperture Ledger is a premium white analytics interface where quiet optical spacing, slate typography, cyan signal light, and copper confidence markers make data feel precise without resorting to dashboard clichés.

### Values

- product-first neutrality
- evidence-led contrast
- quiet premium whitespace
- analytical restraint
- semantic color scarcity

### Anti-Values

- rainbow charting
- colored side rails or decorative stripes
- generic SaaS dashboard density
- neon cyberpunk glow
- notebook dots or square grids

### Visual Character

- Large white canvas with mist-gray inset panels, no texture, and a centered max-width workspace that creates Apple-like negative space around dense product details.
- Cyan appears as thin luminous data strokes, focus rings, and active numeric state while copper appears only as confidence, threshold, and decision markers.
- Cards use a single committed 22px radius, hairline slate borders, and barely-there layered shadows instead of colorful borders, rails, or stripes.
- Analytics are expressed through tonal slate bars, cyan trend overlays, and copper threshold pins rather than rainbow segments or default chart palettes.
- Typography pairs crisp geometric headings with tabular mono numerals, using tight letter spacing and wide row gutters for calm financial-instrument precision.

## Rules

### Composition

Compose like a product briefing surface: one spacious hero decision area, one evidence rail of compact metrics, and analytical modules that align to content columns rather than a rigid visible grid.

### Density

Medium-low density with generous gutters; tables may be information-rich but must maintain 18px vertical padding and calm row separation.

### Hierarchy

Use Manrope for decisive headings, Inter for explanation, and Roboto Mono for all values; hierarchy comes from size, whitespace, and tabular alignment before color.

### Signature Patterns

- Optical aperture cards: white rounded panels set into mist-gray bays with subtle inner highlight and a shadow that reads as precision glass rather than SaaS chrome.
- Dual-accent analytics: tonal slate data structures carry the baseline while cyan draws the active comparison and copper marks thresholds, approvals, or risk decisions.
- Monospace evidence capsules: compact pills combine Roboto Mono numerals with tiny uppercase labels and a single cyan or copper dot used only when semantic.
- Quiet command surfaces: buttons and controls stay white or slate with cyan focus halos; copper is reserved for irreversible or threshold-related interaction states.
- Non-rainbow chart grammar: bars, paths, and matrices use slate opacity ramps with only one cyan highlight and one copper marker in any visible chart.

## Layout

### Breakpoints

mobile 375px, tablet 768px, desktop 1200px, wide 1440px

### Grid

Invisible 12-column content grid at desktop, collapsing to 6 and 1 columns without visible grid lines or background pattern.

### Whitespace

Outer whitespace is treated as a premium material: 32-64px margins on large screens and never filled with decoration.

## Guidance

### Do

- Use cyan for live comparison, selected states, and primary analytical insight.
- Use copper sparingly for thresholds, confidence checks, warnings, and human approvals.
- Let slate tonal variation carry most chart and table structure.
- Keep white backgrounds clean, untextured, and free of dots or square grids.

### Don't

- Do not use rainbow charts, multicolor KPI cards, confetti, or arbitrary extra vivid hues.
- Do not add colored side rails, decorative stripes, or accent borders on cards and rows.
- Do not use generic dashboard widgets without a believable product decision scene.
- Do not place dotted notebook, point-grid, square-grid, or graph-paper backgrounds behind the UI.

Aperture Ledger is a premium white analytics interface where quiet optical spacing, slate typography, cyan signal light, and copper confidence markers make data feel precise without resorting to dashboard clichés.

### Values

- product-first neutrality
- evidence-led contrast
- quiet premium whitespace
- analytical restraint
- semantic color scarcity

### Anti-Values

- rainbow charting
- colored side rails or decorative stripes
- generic SaaS dashboard density

## 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/en-019e4646-8b49-7313-830f-19c07408882e/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.

# Aperture Ledger shadcn/ui Components

Artifact: `component-recipes-v1`
Author: `katagami-ui-projection`
Language ID: `en-019e4646-8b49-7313-830f-19c07408882e`
Slug: `premium-white-cyan-copper-analytics`

## Intent

Aperture Ledger is a premium white analytics interface where quiet optical spacing, slate typography, cyan signal light, and copper confidence markers make data feel precise without resorting to dashboard clichés.

## 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": "#E9FBFF",
  "background": "#FFFFFF",
  "border": "#667381",
  "error": "#B94B4B",
  "info": "#007A9F",
  "muted": "#5C6672",
  "primary": "#007A9F",
  "secondary": "#9A512C",
  "success": "#2F7D66",
  "surface": "#F7F9FB",
  "text": "#18212B",
  "warning": "#9A512C"
}

Typography:

{
  "base_size": "16px",
  "body_font": "Inter",
  "google_fonts_url": "https://fonts.googleapis.com/css2?family=Inter:wght@400;500;600;700&family=Manrope:wght@600;700;800&family=Roboto+Mono:wght@500;600&display=swap",
  "heading_font": "Manrope",
  "letter_spacing": "-0.025em",
  "line_height": 1.5,
  "mono_font": "Roboto Mono",
  "scale_ratio": 1.22
}

## Visual character to preserve

- Large white canvas with mist-gray inset panels, no texture, and a centered max-width workspace that creates Apple-like negative space around dense product details.
- Cyan appears as thin luminous data strokes, focus rings, and active numeric state while copper appears only as confidence, threshold, and decision markers.
- Cards use a single committed 22px radius, hairline slate borders, and barely-there layered shadows instead of colorful borders, rails, or stripes.
- Analytics are expressed through tonal slate bars, cyan trend overlays, and copper threshold pins rather than rainbow segments or default chart palettes.
- Typography pairs crisp geometric headings with tabular mono numerals, using tight letter spacing and wide row gutters for calm financial-instrument precision.

  ]
}

## 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/premium-white-cyan-copper-analytics/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 cyan for live comparison, selected states, and primary analytical insight.; Use copper sparingly for thresholds, confidence checks, warnings, and human approvals.; Let slate tonal variation carry most chart and table structure.; Keep white backgrounds clean, untextured, and free of dots or square grids.
- Do not: Do not use rainbow charts, multicolor KPI cards, confetti, or arbitrary extra vivid hues.; Do not add colored side rails, decorative stripes, or accent borders on cards and rows.; Do not use generic dashboard widgets without a believable product decision scene.; Do not place dotted notebook, point-grid, square-grid, or graph-paper backgrounds behind the UI.

## Copy-paste component example
