rules
composition
Use one dominant reading artifact: a document workspace with a central text rail and persistent marginal context. Side notes align to line groups, not to arbitrary cards, and at least one note crosses the grid as a bracketed annotation.
density
High information density remains light by keeping line length under 68ch, line height around 1.62, metadata at 12-13px, and spacing groups based on an 8px rhythm with large section gaps only between distinct reading tasks.
hierarchy
Primary hierarchy comes from role-based type: serif headings for document structure, Source Sans for interface text, mono for metadata and IDs. Size changes are modest; position, rule weight, and contrast do most of the work.
signature patterns
Marginal note columns align to paragraph anchors with thin indigo or moss connector rules, changing to inline paper slips below tablet widths.Ruled-paper surfaces use repeating-linear-gradient linework behind content blocks and stop at component boundaries so the rhythm is visible but not noisy.Metadata rails use tabular mono labels pinned to the top edge of records, with lower contrast and fixed widths to prevent chip clutter.Nested context stacks as stepped paper slips with 16px left indents, hairline bracket corners, and reduced type scale rather than additional cards.Interactive focus states draw a small bracket marker and darken the nearest rule, expressing annotation selection instead of generic glow or shadow.
layout
breakpoints
mobile <= 640px, tablet 641px-980px, desktop >= 981px; marginal columns become inline annotations on mobile.
grid
Desktop uses a 12-column workspace: 2 columns navigation, 6 columns reading rail, 3 columns marginal notes, and 1 column quiet metadata ticks. Tablet collapses notes beside the rail; mobile converts notes to inline slips after their anchors.
whitespace
Use tight 4-8px spacing inside labels and metadata, 16-24px between related reading groups, and 64px between major document sections so density has breathing room without becoming sparse.
guidance
- Keep the main reading rail uninterrupted and under 68ch.
- Place metadata in stable rails or headers with tabular numerals and muted contrast.
- Use indigo and moss only for rules, brackets, note indices, and quiet emphasis.
- Let vertical rhythm align paragraphs, annotations, and nested slips.
- Turn sidenotes into inline notes on small screens instead of hiding context.
- Do not use generic equal card dashboards or component inventory walls.
- Do not scatter badges, pills, or colorful chips through the main reading path.
- Do not add decorative shadows, gradients, or motif illustrations just to signal Japanese inspiration.
- Do not use oversized display typography or novelty fonts for dense product screens.
- Do not let annotations interrupt paragraphs; anchor them beside or after the relevant text.

# Quiet Marginal Codex ## Philosophy Quiet Marginal Codex is a paper-like product language for dense reading, nested context, and annotation-heavy workflows. It makes AYA feel calm by giving the main text an uninterrupted measure while metadata, provenance, and operator notes live in consistent marginal layers. ### Values - readable density before visual novelty - stable typographic roles over expressive display styling - context that supports the reading path without interrupting it - paper-like restraint with durable product controls - quiet hierarchy through measure, tone, and position ### Anti-Values - generic dashboard cards and decorative empty filler - semantic status colors used as the whole identity - large expressive display type that disrupts dense reading - floating metadata chips that scatter attention - ornamental Japanese motifs without structural utility ### Visual Character - A centered reading rail uses max-width text measures of 62ch with side columns sized in rem units for notes, making marginal context visibly secondary but always aligned to the paragraph rhythm. - Soft ruled paper lines are drawn with repeating-linear-gradient backgrounds and one-pixel inset borders so content blocks feel like annotated documents rather than rounded SaaS cards. - Metadata is rendered as compact small-caps labels with lower contrast, tabular numerals, and fixed placement above or beside the relevant object instead of becoming colorful badges. - Annotation accents use desaturated indigo and moss as thin left rules, bracket marks, and note indices; they never fill large surfaces or compete with primary text. - Nested context appears through indented paper slips, hairline connectors, and stepped inline notes with reduced font size, preserving one uninterrupted main reading column. ## Tokens ### Borders - **Accent Width**: 2px - **Character**: quiet document rules: low-contrast tan for structure, desaturated indigo or moss for annotation state - **Default Width**: 1px - **Style**: solid hairline rules with occasional bracket corners ### Colors | Name | Value | |------|-------| | accent | `#7B5F8A` | | background | `#F4F0E7` | | border | `#D8D0C1` | | error | `#9B4E45` | | info | `#53698B` | | muted | `#777568` | | primary | `#2F3F68` | | secondary | `#5A6B53` | | success | `#5F7554` | | surface | `#FBF8F0` | | text | `#282821` | | warning | `#A27845` | ### Motion - **Duration**: 160ms - **Easing**: cubic-bezier(.2,.0,.1,1) - **Philosophy**: Controls reveal focus by darkening rules and sliding a bracket mark 2px inward; no bounce, float, or generic opacity-only motion. ### Radii - **Full**: 9999px - **Lg**: 6px - **Md**: 4px - **None**: 0 - **Sm**: 2px ### Shadows - **Lg**: 0 18px 50px rgba(76,64,44,0.12) - **Md**: 0 8px 22px rgba(76,64,44,0.08) - **Sm**: 0 1px 0 rgba(40,40,33,0.06) ### Spacing - **Base**: 8px - **Scale**: [4,8,12,16,24,32,48,64] ### Surfaces - **Bg Pattern**: repeating-linear-gradient(to bottom, #F4F0E7 0, #F4F0E7 31px, rgba(216,208,193,.55) 32px) - **Card Style**: rectangular paper slips with 1px hairline borders, tiny radius, and inset annotation gutters - **Treatment**: warm paper fields with faint horizontal ruling and no glossy elevation ### Typography - **Base Size**: 16px - **Body Font**: Source Sans 3 - **Google Fonts Url**: https://fonts.googleapis.com/css2?family=Noto+Serif+JP:wght@500;600;700&family=Source+Sans+3:wght@400;500;600;700&family=IBM+Plex+Mono:wght@400;500;600&display=swap - **Heading Font**: Noto Serif JP - **Letter Spacing**: -0.01em - **Line Height**: 1.62 - **Mono Font**: IBM Plex Mono - **Scale Ratio**: 1.18 ## Rules ### Composition Use one dominant reading artifact: a document workspace with a central text rail and persistent marginal context.

# Quiet Marginal Codex
## Overview
Quiet Marginal Codex is a paper-like product language for dense reading, nested context, and annotation-heavy workflows. It makes AYA feel calm by giving the main text an uninterrupted measure while metadata, provenance, and operator notes live in consistent marginal layers.
### Values
- readable density before visual novelty
- stable typographic roles over expressive display styling
- context that supports the reading path without interrupting it
- paper-like restraint with durable product controls
- quiet hierarchy through measure, tone, and position
### Anti-Values
- generic dashboard cards and decorative empty filler
- semantic status colors used as the whole identity
- large expressive display type that disrupts dense reading
- floating metadata chips that scatter attention
- ornamental Japanese motifs without structural utility
### Visual Character
- A centered reading rail uses max-width text measures of 62ch with side columns sized in rem units for notes, making marginal context visibly secondary but always aligned to the paragraph rhythm.
- Soft ruled paper lines are drawn with repeating-linear-gradient backgrounds and one-pixel inset borders so content blocks feel like annotated documents rather than rounded SaaS cards.
- Metadata is rendered as compact small-caps labels with lower contrast, tabular numerals, and fixed placement above or beside the relevant object instead of becoming colorful badges.
- Annotation accents use desaturated indigo and moss as thin left rules, bracket marks, and note indices; they never fill large surfaces or compete with primary text.
- Nested context appears through indented paper slips, hairline connectors, and stepped inline notes with reduced font size, preserving one uninterrupted main reading column.
## Colors

## Components
### Composition
Use one dominant reading artifact: a document workspace with a central text rail and persistent marginal context. Side notes align to line groups, not to arbitrary cards, and at least one note crosses the grid as a bracketed annotation.
### Density
High information density remains light by keeping line length under 68ch, line height around 1.62, metadata at 12-13px, and spacing groups based on an 8px rhythm with large section gaps only between distinct reading tasks.
### Hierarchy
Primary hierarchy comes from role-based type: serif headings for document structure, Source Sans for interface text, mono for metadata and IDs. Size changes are modest; position, rule weight, and contrast do most of the work.
### Signature Patterns
- Marginal note columns align to paragraph anchors with thin indigo or moss connector rules, changing to inline paper slips below tablet widths.
- Ruled-paper surfaces use repeating-linear-gradient linework behind content blocks and stop at component boundaries so the rhythm is visible but not noisy.
- Metadata rails use tabular mono labels pinned to the top edge of records, with lower contrast and fixed widths to prevent chip clutter.
- Nested context stacks as stepped paper slips with 16px left indents, hairline bracket corners, and reduced type scale rather than additional cards.
- Interactive focus states draw a small bracket marker and darken the nearest rule, expressing annotation selection instead of generic glow or shadow.
## 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-019edc17-cc95-76e2-8c26-e3517a62f699/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 the main reading rail uninterrupted and under 68ch.
- Do Place metadata in stable rails or headers with tabular numerals and muted contrast.
- Do Use indigo and moss only for rules, brackets, note indices, and quiet emphasis.
- Do Let vertical rhythm align paragraphs, annotations, and nested slips.
- Do Turn sidenotes into inline notes on small screens instead of hiding context.
- Don't Do not use generic equal card dashboards or component inventory walls.
- Don't Do not scatter badges, pills, or colorful chips through the main reading path.
- Don't Do not add decorative shadows, gradients, or motif illustrations just to signal Japanese inspiration.
- Don't Do not use oversized display typography or novelty fonts for dense product screens.
- Don't Do not let annotations interrupt paragraphs; anchor them beside or after the relevant text.
### Accessibility
Maintain AA contrast for body and controls, never rely on accent color alone for status, keep marginal notes readable at 13px or larger, and preserve visible focus brackets plus semantic labels.
### Usage Context
Best for research products, policy review tools, literary annotation systems, support knowledge bases, and AI copilots that need to show source context without overwhelming the user.

# Quiet Marginal Codex shadcn/ui Components
Artifact: `component-recipes-v1`
Author: `katagami-ui-projection`
Language ID: `en-019edc17-cc95-76e2-8c26-e3517a62f699`
Slug: `quiet-marginal-codex`
## Intent
Quiet Marginal Codex is a paper-like product language for dense reading, nested context, and annotation-heavy workflows. It makes AYA feel calm by giving the main text an uninterrupted measure while metadata, provenance, and operator notes live in consistent marginal layers.
## 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
- A centered reading rail uses max-width text measures of 62ch with side columns sized in rem units for notes, making marginal context visibly secondary but always aligned to the paragraph rhythm.
- Soft ruled paper lines are drawn with repeating-linear-gradient backgrounds and one-pixel inset borders so content blocks feel like annotated documents rather than rounded SaaS cards.
- Metadata is rendered as compact small-caps labels with lower contrast, tabular numerals, and fixed placement above or beside the relevant object instead of becoming colorful badges.
- Annotation accents use desaturated indigo and moss as thin left rules, bracket marks, and note indices; they never fill large surfaces or compete with primary text.
- Nested context appears through indented paper slips, hairline connectors, and stepped inline notes with reduced font size, preserving one uninterrupted main reading column.
## ShadSync visual profile

"motion": "still",

]
}
## 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/quiet-marginal-codex/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 the main reading rail uninterrupted and under 68ch.; Place metadata in stable rails or headers with tabular numerals and muted contrast.; Use indigo and moss only for rules, brackets, note indices, and quiet emphasis.; Let vertical rhythm align paragraphs, annotations, and nested slips.; Turn sidenotes into inline notes on small screens instead of hiding context.
- Do not: Do not use generic equal card dashboards or component inventory walls.; Do not scatter badges, pills, or colorful chips through the main reading path.; Do not add decorative shadows, gradients, or motif illustrations just to signal Japanese inspiration.; Do not use oversized display typography or novelty fonts for dense product screens.; Do not let annotations interrupt paragraphs; anchor them beside or after the relevant text.
## 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; marginal columns become inline annotations on mobile.",
"grid": "Desktop uses a 12-column workspace: 2 columns navigation, 6 columns reading rail, 3 columns marginal notes, and 1 column quiet metadata ticks. Tablet collapses notes beside the rail; mobile converts notes to inline slips after their anchors.",
"whitespace": "Use tight 4-8px spacing inside labels and metadata, 16-24px between related reading groups, and 64px between major document sections so density has breathing room without becoming sparse."
