composition

Anchor each screen with a readable central measure and a subordinate annotation rail; avoid equal card grids unless the content is truly parallel.

density

High density is allowed when rows share a strict 8px rhythm, metadata is compact, and secondary context is visually recessed.

hierarchy

Use type scale, weight, line length, rule placement, and spacing before using color; titles are serif, body is sans, metadata is mono.

signature patterns
Margin-note rails place secondary context in 22ch side columns with 11px muted type and short vertical rules.Context ladders use nested left borders, hanging labels, and progressive disclosure counts to show depth without new cards.Metadata sutras are single-line mono rows with dotted separators, tabular numerals, and tiny uppercase labels.Reading panels use generous line-height with 62ch max measure while surrounding controls compress to preserve calm space.
layout
breakpoints

mobile <= 640px, tablet 641px-980px, desktop >= 981px; annotation rail becomes inline indented notes below its parent section.

density

Information density is high but softened by predictable measure, flat surfaces, and quiet secondary type.

grid

Desktop uses a 12-column grid with a 7-column reading area, 3-column annotation rail, and 2-column operations strip; tablet uses 8 columns, mobile one column.

whitespace

Outer page spacing is 32-56px while internal text rhythm uses 8px steps; dense metadata can use 4px gaps only inside a row.

guidance
do
  • Keep main reading text between 56ch and 68ch with line-height near 1.6 for long contextual passages.
  • Use annotation rails, indents, and left rules for secondary information instead of extra saturated panels.
  • Compress metadata into mono rows with consistent separators and tabular numerals.
  • Let one sumi-blue accent mark active focus, links, or selected disclosure states.
avoid
  • Do not rely on bright status colors, gradients, or multiple accent hues to create hierarchy.
  • Do not turn every contextual fragment into a shadowed card or rounded SaaS widget.
  • Do not use center-aligned text blocks, wide measures, or loose inconsistent spacing for dense content.
  • Do not make annotations decorative; every note must clarify provenance, confidence, history, or next action.

# AYA Margin Script

## Philosophy

AYA Margin Script is a quiet Japanese-inspired product language for text-heavy context systems: it treats the main record as a calm reading column and every supporting detail as a disciplined margin note, rule, chip, or nested disclosure rather than decorative UI chrome.

### Values

- readable density
- annotation as structure
- quiet hierarchy
- calm vertical rhythm
- progressive context

### Anti-Values

- ornamental minimalism
- color-coded clutter
- dashboard card sameness
- floating chrome and heavy shadows

### Visual Character

- A warm off-white page with ivory panels, one hairline ink border, and no filled color blocks except tiny status accents.
- A two-measure layout uses a 62ch primary text column plus a 22ch annotation rail that collapses into indented notes on small screens.
- Metadata is compressed into 11px letterspaced rows with dotted separators, tabular numerals, and muted ink so dense context stays calm.
- Nested context appears as soft left rules, small disclosure counters, and hanging-label indents rather than separate raised cards.
- Hierarchy relies on restrained type size, weight, line-height, and spacing tokens, with color reserved for a single sumi-blue focus accent.

## Tokens

### Borders

- **Accent Width**: 2px
- **Character**: ink-thin rules, left annotation bars, and square corners with only tiny radius on controls
- **Default Width**: 1px
- **Style**: solid hairline with dotted metadata separators

| text | `#202624` |
| warning | `#A46C2B` |

### Motion

- **Duration**: 140ms

## Rules

### Composition

Anchor each screen with a readable central measure and a subordinate annotation rail; avoid equal card grids unless the content is truly parallel.

### Density

High density is allowed when rows share a strict 8px rhythm, metadata is compact, and secondary context is visually recessed.

### Hierarchy

Use type scale, weight, line length, rule placement, and spacing before using color; titles are serif, body is sans, metadata is mono.

### Signature Patterns

- Margin-note rails place secondary context in 22ch side columns with 11px muted type and short vertical rules.
- Context ladders use nested left borders, hanging labels, and progressive disclosure counts to show depth without new cards.
- Metadata sutras are single-line mono rows with dotted separators, tabular numerals, and tiny uppercase labels.
- Reading panels use generous line-height with 62ch max measure while surrounding controls compress to preserve calm space.

## Layout

### Breakpoints

mobile <= 640px, tablet 641px-980px, desktop >= 981px; annotation rail becomes inline indented notes below its parent section.

### Density

Information density is high but softened by predictable measure, flat surfaces, and quiet secondary type.

### Grid

Desktop uses a 12-column grid with a 7-column reading area, 3-column annotation rail, and 2-column operations strip; tablet uses 8 columns, mobile one column.

### Whitespace

Outer page spacing is 32-56px while internal text rhythm uses 8px steps; dense metadata can use 4px gaps only inside a row.

## Guidance

### Do

- Keep main reading text between 56ch and 68ch with line-height near 1.6 for long contextual passages.
- Use annotation rails, indents, and left rules for secondary information instead of extra saturated panels.
- Compress metadata into mono rows with consistent separators and tabular numerals.
- Let one sumi-blue accent mark active focus, links, or selected disclosure states.

### Don't

- Do not rely on bright status colors, gradients, or multiple accent hues to create hierarchy.
- Do not turn every contextual fragment into a shadowed card or rounded SaaS widget.
- Do not use center-aligned text blocks, wide measures, or loose inconsistent spacing for dense content.
- Do not make annotations decorative; every note must clarify provenance, confidence, history, or next action.

### Accessibility

Maintain AA contrast, keep annotation text at least 12px where it carries meaning, provide visible focus with a 2px blue outline, and never encode state by color alone.

### Usage Context

Best for research assistants, knowledge bases, editorial review tools, clinical notes, legal context work, and any product where layered text must remain readable.

# AYA Margin Script

## Overview

AYA Margin Script is a quiet Japanese-inspired product language for text-heavy context systems: it treats the main record as a calm reading column and every supporting detail as a disciplined margin note, rule, chip, or nested disclosure rather than decorative UI chrome.

### Values

- readable density
- annotation as structure
- quiet hierarchy
- calm vertical rhythm
- progressive context

### Anti-Values

- ornamental minimalism
- color-coded clutter
- dashboard card sameness
- floating chrome and heavy shadows

### Visual Character

- A warm off-white page with ivory panels, one hairline ink border, and no filled color blocks except tiny status accents.
- A two-measure layout uses a 62ch primary text column plus a 22ch annotation rail that collapses into indented notes on small screens.
- Metadata is compressed into 11px letterspaced rows with dotted separators, tabular numerals, and muted ink so dense context stays calm.
- Nested context appears as soft left rules, small disclosure counters, and hanging-label indents rather than separate raised cards.
- Hierarchy relies on restrained type size, weight, line-height, and spacing tokens, with color reserved for a single sumi-blue focus accent.

## 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 | `#315F7C` |
| background | `#F7F4EC` |
| border | `#D8D1C2` |
| error | `#9A3B32` |
| info | `#315F7C` |

- **Lg**: `8px`
- **Md**: `4px`
- **None**: `0px`

- **Character**: ink-thin rules, left annotation bars, and square corners with only tiny radius on controls
- **Default Width**: 1px
- **Style**: solid hairline with dotted metadata separators

## Components

High density is allowed when rows share a strict 8px rhythm, metadata is compact, and secondary context is visually recessed.

### Hierarchy

Use type scale, weight, line length, rule placement, and spacing before using color; titles are serif, body is sans, metadata is mono.

### Signature Patterns

- Margin-note rails place secondary context in 22ch side columns with 11px muted type and short vertical rules.
- Context ladders use nested left borders, hanging labels, and progressive disclosure counts to show depth without new cards.

- Reading panels use generous line-height with 62ch max measure while surrounding controls compress to preserve calm space.

## 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-019edab2-9a29-7a93-84b3-f71453f577c1/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 Keep main reading text between 56ch and 68ch with line-height near 1.6 for long contextual passages.
- Do Use annotation rails, indents, and left rules for secondary information instead of extra saturated panels.
- Do Compress metadata into mono rows with consistent separators and tabular numerals.
- Do Let one sumi-blue accent mark active focus, links, or selected disclosure states.
- Don't Do not rely on bright status colors, gradients, or multiple accent hues to create hierarchy.
- Don't Do not turn every contextual fragment into a shadowed card or rounded SaaS widget.
- Don't Do not use center-aligned text blocks, wide measures, or loose inconsistent spacing for dense content.
- Don't Do not make annotations decorative; every note must clarify provenance, confidence, history, or next action.

### Accessibility

Maintain AA contrast, keep annotation text at least 12px where it carries meaning, provide visible focus with a 2px blue outline, and never encode state by color alone.

### Usage Context

Best for research assistants, knowledge bases, editorial review tools, clinical notes, legal context work, and any product where layered text must remain readable.

# AYA Margin Script shadcn/ui Components

Artifact: `component-recipes-v1`
Author: `katagami-ui-projection`
Language ID: `en-019edab2-9a29-7a93-84b3-f71453f577c1`
Slug: `aya-margin-script`

## Intent

AYA Margin Script is a quiet Japanese-inspired product language for text-heavy context systems: it treats the main record as a calm reading column and every supporting detail as a disciplined margin note, rule, chip, or nested disclosure rather than decorative UI chrome.

## 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": "#315F7C",
  "background": "#F7F4EC",
  "border": "#D8D1C2",
  "error": "#9A3B32",
  "info": "#315F7C",
  "muted": "#7E8580",
  "primary": "#1F2A2A",
  "secondary": "#6D746F",
  "success": "#4D6A45",
  "surface": "#FFFCF4",
  "text": "#202624",
  "warning": "#A46C2B"
}

Typography:

{
  "base_size": "16px",
  "body_font": "Noto Sans JP",
  "google_fonts_url": "https://fonts.googleapis.com/css2?family=IBM+Plex+Mono:wght@400;500&family=Noto+Sans+JP:wght@400;500;600&family=Shippori+Mincho:wght@500;600&display=swap",
  "heading_font": "Shippori Mincho",
  "letter_spacing": "-0.01em",
  "line_height": 1.62,
  "mono_font": "IBM Plex Mono",
  "scale_ratio": 1.18
}

## Visual character to preserve

- A warm off-white page with ivory panels, one hairline ink border, and no filled color blocks except tiny status accents.
- A two-measure layout uses a 62ch primary text column plus a 22ch annotation rail that collapses into indented notes on small screens.
- Metadata is compressed into 11px letterspaced rows with dotted separators, tabular numerals, and muted ink so dense context stays calm.
- Nested context appears as soft left rules, small disclosure counters, and hanging-label indents rather than separate raised cards.
- Hierarchy relies on restrained type size, weight, line-height, and spacing tokens, with color reserved for a single sumi-blue focus accent.

## ShadSync visual profile

    "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/aya-margin-script/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: Keep main reading text between 56ch and 68ch with line-height near 1.6 for long contextual passages.; Use annotation rails, indents, and left rules for secondary information instead of extra saturated panels.; Compress metadata into mono rows with consistent separators and tabular numerals.; Let one sumi-blue accent mark active focus, links, or selected disclosure states.
- Do not: Do not rely on bright status colors, gradients, or multiple accent hues to create hierarchy.; Do not turn every contextual fragment into a shadowed card or rounded SaaS widget.; Do not use center-aligned text blocks, wide measures, or loose inconsistent spacing for dense content.; Do not make annotations decorative; every note must clarify provenance, confidence, history, or next action.

## 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 <= 640px, tablet 641px-980px, desktop >= 981px; annotation rail becomes inline indented notes below its parent section.",
  "density": "Information density is high but softened by predictable measure, flat surfaces, and quiet secondary type.",
  "grid": "Desktop uses a 12-column grid with a 7-column reading area, 3-column annotation rail, and 2-column operations strip; tablet uses 8 columns, mobile one column.",
  "whitespace": "Outer page spacing is 32-56px while internal text rhythm uses 8px steps; dense metadata can use 4px gaps only inside a row."
