signature patterns
A sticky table-of-contents rail uses amber text and a translucent highlighter strip for the current section instead of a bordered active pill.Inline important terms sit on a soft linear-gradient highlighter sweep that covers the lower half of the text without changing text color.Reading panels use borderless cream surface shifts and oversized whitespace gutters to imply regions without rules or card outlines.Code examples use a pale inset wash, mono labels, and thin amber line cues rather than dark terminal blocks or boxed borders.Focus states form a two-pixel amber outline with offset on controls and links, keeping accessibility visible but restrained.

Responsive three-zone reading grid: left contents rail, central 68ch article column, right annotation rail that collapses below tablet.

whitespace

Whitespace is the primary separator: 32-64px section gaps, wide outer margins, and paragraph rhythm tuned for long sessions.

guidance
do
  • Keep body text charcoal on near-white surfaces with ample line height.
  • Use the amber accent only for links, focus, active navigation, highlights, and code markers.
  • Let headings, spacing, and measure create hierarchy before adding surface changes.
  • Keep code blocks calm and readable with pale backgrounds and mono labels.
avoid
  • Do not add decorative multi-color accents or gradients beyond highlighter marks.
  • Do not box every region with borders, cards, or heavy shadows.
  • Do not stretch prose full width or reduce paragraph rhythm for dashboard density.
  • Do not use low-contrast gray for primary reading content.

# Quiet Annotated Reader

## Philosophy

A quiet, high-contrast technical reading language where the page recedes behind prose, code, annotations, and measured navigation for long-form knowledge work.

### Values

- sustained legibility over decorative novelty
- typographic hierarchy as the primary interface structure
- annotation and focus states that feel like careful highlighter marks
- wide breathing room with restrained density changes

### Anti-Values

- border-heavy cards and dashboard chrome
- multi-accent brand decoration
- full-width prose that tires the eye
- low-contrast gray body copy

### Visual Character

- Use a near-white page background with a slightly warmer reading column surface and charcoal text at high contrast.
- Constrain prose blocks to a 68ch measure while metadata, table of contents, and annotations sit in quiet side rails.
- Replace visible card borders with spacing, soft background temperature shifts, and typography-first section breaks.
- Apply one muted amber highlighter accent as translucent inline marks, focus rings, active nav, and selected key terms.
- Render code in calm inset panels with no hard outline, using mono type, pale wash backgrounds, and amber line markers.

- Inline important terms sit on a soft linear-gradient highlighter sweep that covers the lower half of the text without changing text color.
- Reading panels use borderless cream surface shifts and oversized whitespace gutters to imply regions without rules or card outlines.
- Code examples use a pale inset wash, mono labels, and thin amber line cues rather than dark terminal blocks or boxed borders.
- Focus states form a two-pixel amber outline with offset on controls and links, keeping accessibility visible but restrained.

## Guidance

### Do

- Keep body text charcoal on near-white surfaces with ample line height.
- Use the amber accent only for links, focus, active navigation, highlights, and code markers.

# Quiet Annotated Reader

## Overview

A quiet, high-contrast technical reading language where the page recedes behind prose, code, annotations, and measured navigation for long-form knowledge work.

### Values

- sustained legibility over decorative novelty
- typographic hierarchy as the primary interface structure
- annotation and focus states that feel like careful highlighter marks
- wide breathing room with restrained density changes

### Anti-Values

- border-heavy cards and dashboard chrome
- multi-accent brand decoration
- full-width prose that tires the eye
- low-contrast gray body copy

### Visual Character

- Use a near-white page background with a slightly warmer reading column surface and charcoal text at high contrast.
- Constrain prose blocks to a 68ch measure while metadata, table of contents, and annotations sit in quiet side rails.
- Replace visible card borders with spacing, soft background temperature shifts, and typography-first section breaks.
- Apply one muted amber highlighter accent as translucent inline marks, focus rings, active nav, and selected key terms.
- Render code in calm inset panels with no hard outline, using mono type, pale wash backgrounds, and amber line markers.

## Colors

Use the YAML color tokens as the normative palette. The prose below names the roles agents should preserve when generating UI.

| Token | Value |
|-------|-------|

## Components

### Composition

Compose every screen around a bounded reading measure with optional quiet rails; horizontal alignment and whitespace replace panels and outlines.

### Density

Comfortable long-form density with generous paragraph rhythm; compact density is allowed only for code, metadata, and small tables.

### Hierarchy

### Signature Patterns

- A sticky table-of-contents rail uses amber text and a translucent highlighter strip for the current section instead of a bordered active pill.
- Inline important terms sit on a soft linear-gradient highlighter sweep that covers the lower half of the text without changing text color.
- Reading panels use borderless cream surface shifts and oversized whitespace gutters to imply regions without rules or card outlines.

- Focus states form a two-pixel amber outline with offset on controls and links, keeping accessibility visible but restrained.

## 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-019ee326-5e31-7802-bc42-c49039a2297a/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 body text charcoal on near-white surfaces with ample line height.
- Do Use the amber accent only for links, focus, active navigation, highlights, and code markers.
- Do Let headings, spacing, and measure create hierarchy before adding surface changes.
- Do Keep code blocks calm and readable with pale backgrounds and mono labels.
- Don't Do not add decorative multi-color accents or gradients beyond highlighter marks.
- Don't Do not box every region with borders, cards, or heavy shadows.
- Don't Do not stretch prose full width or reduce paragraph rhythm for dashboard density.
- Don't Do not use low-contrast gray for primary reading content.

# Quiet Annotated Reader shadcn/ui Components

Artifact: `component-recipes-v1`
Author: `katagami-ui-projection`
Language ID: `en-019ee326-5e31-7802-bc42-c49039a2297a`
Slug: `quiet-annotated-reader`

## Intent

A quiet, high-contrast technical reading language where the page recedes behind prose, code, annotations, and measured navigation for long-form knowledge work.

## 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": "#C8933A",
  "background": "#FAFAF7",
  "border": "#E6E0D3",
  "error": "#A0473D",
  "info": "#4E6F8F",
  "muted": "#78746A",
  "primary": "#262521",
  "secondary": "#6F6A5F",
  "success": "#4F7A55",
  "surface": "#FFFFFF",
  "text": "#24231F",
  "warning": "#B9822E"
}

Typography:

{
  "base_size": "17px",
  "body_font": "Atkinson Hyperlegible",
  "google_fonts_url": "https://fonts.googleapis.com/css2?family=Atkinson+Hyperlegible:wght@400;700&family=IBM+Plex+Mono:wght@400;500;600&family=Literata:wght@500;600;700&display=swap",
  "heading_font": "Literata",
  "letter_spacing": "-0.01em",
  "line_height": 1.68,
  "mono_font": "IBM Plex Mono",
  "scale_ratio": 1.22
}

## Visual character to preserve

- Use a near-white page background with a slightly warmer reading column surface and charcoal text at high contrast.
- Constrain prose blocks to a 68ch measure while metadata, table of contents, and annotations sit in quiet side rails.
- Replace visible card borders with spacing, soft background temperature shifts, and typography-first section breaks.
- Apply one muted amber highlighter accent as translucent inline marks, focus rings, active nav, and selected key terms.
- Render code in calm inset panels with no hard outline, using mono type, pale wash backgrounds, and amber line markers.

## ShadSync visual profile

{
  "family": "brutalist",
  "material": "ink",
  "contour": "pebble",
  "border": "solid",
  "underlay": true,
  "grain": false,
  "stickerBadges": false,
  "motion": "still",
  "density": "balanced",
  "accents": [
    "primary",
    "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/quiet-annotated-reader/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 body text charcoal on near-white surfaces with ample line height.; Use the amber accent only for links, focus, active navigation, highlights, and code markers.; Let headings, spacing, and measure create hierarchy before adding surface changes.; Keep code blocks calm and readable with pale backgrounds and mono labels.
- Do not: Do not add decorative multi-color accents or gradients beyond highlighter marks.; Do not box every region with borders, cards, or heavy shadows.; Do not stretch prose full width or reduce paragraph rhythm for dashboard density.; Do not use low-contrast gray for primary reading content.

## Copy-paste component example

This generated starter proves the import shape. Production Katagami agents should replace it with a language-specific product composition.
