# AYA Quiet Thread Color System

## Philosophy

AYA Quiet Thread Color System is a light, warm-neutral interface language for dense reading and calm knowledge work, using ink-like text, quiet thread lines, and restrained aizome indigo accents.

### Values

- calm legibility
- threaded continuity
- restrained semantic color
- dense but breathable reading
- artifact-ready production polish

### Anti-Values

- loud gradients
- decorative noise
- browser-default controls
- low-contrast gray text
- placeholder artifact states

### Visual Character

- warm gray paper surfaces crossed by hairline thread dividers
- aizome indigo and muted clay accents reserved for active state and semantic emphasis
- compact editorial cards, reading rails, and verification ledgers with clear hierarchy
- soft square radii and thin borders that feel stitched rather than boxed in

# AYA Quiet Thread Color System

## Overview

AYA Quiet Thread Color System is a light, warm-neutral interface language for dense reading and calm knowledge work, using ink-like text, quiet thread lines, and restrained aizome indigo accents.

### Values

- calm legibility
- threaded continuity
- restrained semantic color
- dense but breathable reading
- artifact-ready production polish

### Anti-Values

- loud gradients
- decorative noise
- browser-default controls
- low-contrast gray text
- placeholder artifact states

### Visual Character

- warm gray paper surfaces crossed by hairline thread dividers
- aizome indigo and muted clay accents reserved for active state and semantic emphasis
- compact editorial cards, reading rails, and verification ledgers with clear hierarchy
- soft square radii and thin borders that feel stitched rather than boxed in

## 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 | `#3E5F8A` |
| background | `#F6F1E8` |
| border | `#D8CDBB` |

## 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-019edc15-f3c9-78e2-a52b-486ae38f7a7a/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 warm neutral surfaces and ink text
- Do show real verification and artifact state
- Do keep controls custom and visibly styled
- Do use indigo accents sparingly
- Don't use saturated rainbow palettes
- Don't ship empty placeholders
- Don't hide artifact readiness
- Don't rely on default form styling

# AYA Quiet Thread Color System shadcn/ui Components

Artifact: `component-recipes-v1`
Author: `katagami-ui-projection`
Language ID: `en-019edc15-f3c9-78e2-a52b-486ae38f7a7a`
Slug: `aya-quiet-thread-color-system`

## Intent

AYA Quiet Thread Color System is a light, warm-neutral interface language for dense reading and calm knowledge work, using ink-like text, quiet thread lines, and restrained aizome indigo accents.

## 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": "#3E5F8A",
  "background": "#F6F1E8",
  "border": "#D8CDBB",
  "error": "#A0443E",
  "info": "#3E5F8A",
  "muted": "#6D746F",
  "primary": "#2F4F73",
  "secondary": "#8B6F47",
  "success": "#3D7653",
  "surface": "#FFFCF6",
  "surface_alt": "#EFE7D8",
  "text": "#1F2528",
  "warning": "#A76E2B"
}

Typography:

{
  "base_size": "16px",
  "body_font": "Inter",
  "google_fonts_url": "https://fonts.googleapis.com/css2?family=Inter:wght@400;500;600;700;800&family=IBM+Plex+Mono:wght@500;600&display=swap",
  "heading_font": "Inter",
  "letter_spacing": "-0.01em",
  "line_height": 1.55,
  "mono_font": "IBM Plex Mono",
  "scale_ratio": 1.2
}

## Visual character to preserve

- warm gray paper surfaces crossed by hairline thread dividers
- aizome indigo and muted clay accents reserved for active state and semantic emphasis
- compact editorial cards, reading rails, and verification ledgers with clear hierarchy
- soft square radii and thin borders that feel stitched rather than boxed in

## ShadSync visual profile

{
  "family": "paper-collage",
  "material": "paper",
  "contour": "default",
  "border": "dashed",
  "underlay": false,
  "grain": true,
  "stickerBadges": false,
  "motion": "still",
  "density": "dense",
  "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/aya-quiet-thread-color-system/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 warm neutral surfaces and ink text; show real verification and artifact state; keep controls custom and visibly styled; use indigo accents sparingly
- Do not: use saturated rainbow palettes; ship empty placeholders; hide artifact readiness; rely on default form styling

## Copy-paste component example

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