Reticle Ledger

# Reticle Ledger

## Philosophy

Reticle Ledger is a precision optical-instrument analytics surface: product evidence laid on a clean white plate where slate hairlines carry the structure, a single cyan trace marks what is live, and a copper pin marks only the thresholds a human must approve.

### Values

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

### Anti-Values

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

### Visual Character

- A pure white canvas with mist-gray recessed analytical bays, no texture, and a centred max-width workspace that treats outer whitespace as a premium material.
- Cyan appears only as thin luminous data strokes, focus halos, and the active numeric state; copper appears only as confidence, threshold, and decision markers.
- Optical aperture cards use a committed 22px radius, 1px slate hairline borders, and a barely-there ambient shadow that reads as precision glass rather than SaaS chrome.
- Analytics are expressed through tonal slate opacity ramps with one cyan highlight and one copper threshold pin, never rainbow segments or default chart palettes.
- Manrope decisive headings pair with Inter explanation and Roboto Mono tabular numerals, hierarchy coming from size, whitespace, and alignment before colour.

- **Heading Transform**: none
- **Letter Spacing**: -0.025em
- **Line Height**: 1.55
- **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

### Radii

- **None**: 0
- **Sm**: 10px
- **Md**: 16px
- **Lg**: 22px
- **Full**: 9999px

### Shadows

- **Sm**: 0 1px 2px rgba(22,32,43,0.05)
- **Md**: 0 14px 34px rgba(22,32,43,0.07)
- **Lg**: 0 28px 70px rgba(22,32,43,0.10)

### Spacing

- **Base**: 8px
- **Scale**: [4,8,12,16,24,32,48,64,96]

### Surfaces

- **Bg Pattern**: none; empty white and mist-gray plane changes only
- **Card Style**: white optical cards with 22px radius, slate hairline borders, soft vertical ambient shadow, faint top lens highlight
- **Treatment**: clean white base with mist-gray recessed analytical bays and no dot, grid, or paper texture

### Borders

- **Default Width**: 1px
- **Accent Width**: 2px
- **Style**: solid
- **Character**: low-contrast slate hairlines; accents appear only as interior strokes, focus rings, chart lines, or threshold pins, never as side rails or card stripes

### Motion

- **Duration**: 180ms
- **Easing**: cubic-bezier(0.2, 0.8, 0.2, 1)
- **Philosophy**: micro-lift, opacity clarification, and numeric-state emphasis; settled state is the default and renders with no JavaScript; avoid playful bounce or decorative colour sweep

## Rules

### Composition

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

### Hierarchy

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

### Density

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

### Signature

- Optical aperture cards: white rounded panels set into mist-gray bays with a subtle top 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

### Grid

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

### Whitespace

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

### Density

medium-low

### Responsive

Single-column stack on mobile; non-essential nav links and lower-priority table columns hidden; only the full-bleed hero spans 100vw; contained content capped and centred on ultra-wide.

### Breakpoints

- **Mobile**: 390px
- **Tablet**: 768px
- **Desktop**: 1200px
- **Wide**: 1440px

## Guidance

### Do

- Use cyan for live comparison, selected states, and the 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, multicolour KPI cards, confetti, or arbitrary extra vivid hues.
- Do not add coloured side rails, decorative stripes, or accent borders on cards and rows.
- Do not nest cards or trap the nav in a floating rounded card or pill bar.
- Do not place dotted notebook, point-grid, square-grid, or graph-paper backgrounds behind the UI.

### Accessibility

Body text 17px+ with high contrast (slate ink on white); tabular numerals for figures; cyan focus halos on every control; status carried by dot plus label, never colour alone; prefers-reduced-motion respected.

## Imagery Direction

### Pairs With

calibration-plate-optical-slate-technique

### Summary

Subjects reconstructed from fine hairline contour lines on a near-white field, form carried by tonal slate opacity ramps, scattered registration cross-ticks and concentric optical guide rings, one luminous cyan data trace and one copper threshold pin.

### Subjects

- optical aperture iris
- calibration plate
- measuring instrument
- lens diaphragm
- precision gauge

### Usage

One full-bleed landing hero in the calibration-plate technique; keep the field near-white and untextured, restrain accents to one cyan trace and one copper pin.

### Visual Character

- A pure white canvas with mist-gray recessed analytical bays, no texture, and a centred max-width workspace that treats outer whitespace as a premium material.
- Cyan appears only as thin luminous data strokes, focus halos, and the active numeric state; copper appears only as confidence, threshold, and decision markers.
- Optical aperture cards use a committed 22px radius, 1px slate hairline borders, and a barely-there ambient shadow that reads as precision glass rather than SaaS chrome.
- Analytics are expressed through tonal slate opacity ramps with one cyan highlight and one copper threshold pin, never rainbow segments or default chart palettes.
- Manrope decisive headings pair with Inter explanation and Roboto Mono tabular numerals, hierarchy coming from size, whitespace, and alignment before colour.

## 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-019ef96c-004b-7773-858a-d6b992c38c42/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 cyan for live comparison, selected states, and the primary analytical insight.
- Do Use copper sparingly for thresholds, confidence checks, warnings, and human approvals.
- Do Let slate tonal variation carry most chart and table structure.
- Do Keep white backgrounds clean, untextured, and free of dots or square grids.
- Don't Do not use rainbow charts, multicolour KPI cards, confetti, or arbitrary extra vivid hues.
- Don't Do not add coloured side rails, decorative stripes, or accent borders on cards and rows.
- Don't Do not nest cards or trap the nav in a floating rounded card or pill bar.
- Don't Do not place dotted notebook, point-grid, square-grid, or graph-paper backgrounds behind the UI.

### Accessibility

Body text 17px+ with high contrast (slate ink on white); tabular numerals for figures; cyan focus halos on every control; status carried by dot plus label, never colour alone; prefers-reduced-motion respected.
