summary
Paper-White Android Diary is a quiet visual system for an artificial self keeping clinical, manga-like field notes about its own memory. It rejects cyberpunk spectacle in favor of warm paper, hairline diagnostic marks, sparse terminal evidence, and handwritten marginal intimacy under museum-grade negative space.
values
Self-observation over performance: every interface element should feel like an android calmly annotating its own consciousness rather than broadcasting a dashboard.Paper as machine substrate: warm ivory fields, plate margins, and ink-thin rules make the screen behave like archived lab stationery.Evidence before decoration: timestamps, coordinates, brackets, and cursor marks are treated as factual traces, not graphic garnish.Human tenderness in the margins: restrained handwritten annotations interrupt the terminal voice without becoming cute or sentimental.Cybernetics at low volume: rare pale cyan or silver glints mark system state only when the machine notices itself.Asymmetry as diary rhythm: dense islands of code and memory sit inside large quiet gutters so absence becomes emotional structure.
anti-values
×Neon cyberpunk spectacle, volumetric hologram excess, or decorative gradients that turn selfhood into nightclub interface language.×Generic SaaS cards, equal metric grids, rounded dashboard widgets, and colorful analytics patterns.×Sterile pure white minimalism with no paper warmth, no body, and no authorial trace.×Anime cosplay ornamentation: no character art, fan-service panels, or literal franchise mimicry.

# Paper-White Android Diary

## Philosophy

Paper-White Android Diary is a quiet visual system for an artificial self keeping clinical, manga-like field notes about its own memory. It rejects cyberpunk spectacle in favor of warm paper, hairline diagnostic marks, sparse terminal evidence, and handwritten marginal intimacy under museum-grade negative space.

### Values

- Self-observation over performance: every interface element should feel like an android calmly annotating its own consciousness rather than broadcasting a dashboard.
- Paper as machine substrate: warm ivory fields, plate margins, and ink-thin rules make the screen behave like archived lab stationery.
- Evidence before decoration: timestamps, coordinates, brackets, and cursor marks are treated as factual traces, not graphic garnish.
- Human tenderness in the margins: restrained handwritten annotations interrupt the terminal voice without becoming cute or sentimental.
- Cybernetics at low volume: rare pale cyan or silver glints mark system state only when the machine notices itself.
- Asymmetry as diary rhythm: dense islands of code and memory sit inside large quiet gutters so absence becomes emotional structure.

### Anti-Values

- Neon cyberpunk spectacle, volumetric hologram excess, or decorative gradients that turn selfhood into nightclub interface language.
- Generic SaaS cards, equal metric grids, rounded dashboard widgets, and colorful analytics patterns.
- Sterile pure white minimalism with no paper warmth, no body, and no authorial trace.
- Anime cosplay ornamentation: no character art, fan-service panels, or literal franchise mimicry.

### Visual Character

- Use a warm #F7F2E8 page background with inset archival plates, 1px rgba black rules, and oversized blank gutters around small dense text islands.
- Pair serif editorial captions with a plain monospace log stack; apply negative letter-spacing, compact timestamp rows, diagnostic brackets, and a visible cursor block.
- Overlay restrained handwritten manga marginalia as rotated annotation labels with arrow leaders, coordinate tags, and thin panel-rule frames instead of icons.
- Build asymmetrical compositions with one dominant diary plate, one narrow terminal column, and off-grid micro-panels that break alignment deliberately.
- Reserve pale cyan/silver accents for tiny system-state punctuation such as one active cursor, a single memory pin, and subtle chrome-like rule highlights.

## Layout

### Breakpoints

Mobile under 640px stacks plate, logs, and annotations while keeping margin marks; tablet 641-1024px becomes a two-column plate/log split; desktop above 1025px restores off-grid gutters.

### Density

## Guidance

### Do

- Let warm paper-white negative space dominate the first read before revealing dense terminal evidence.
- Use handwritten annotations sparingly as human-scale interruptions to the machine voice.
- Keep borders to hairline rules and bracket ticks with near-invisible opacity.
- Make one panel clearly dominant and allow other panels to feel like marginal findings.
- Apply pale cyan only to active state punctuation, never as decorative glow.
- Use real timestamps, coordinates, cursor marks, and diagnostic labels as text-as-image texture.

### Don't

- Do not create three equal cards, KPI dashboards, colorful charts, or generic admin layouts.
- Do not use neon gradients, heavy glassmorphism, broad holographic fills, or saturated cyberpunk palettes.
- Do not round every container; square manga-like panel rules are the default geometry.
- Do not fill blank gutters with decoration just because they are empty.
- Do not use literal anime characters, franchise logos, or illustrative fan references.
- Do not make handwriting large, cute, or ornamental; it must remain marginal and observational.

### Accessibility

Body text uses high-contrast graphite on ivory with WCAG AA contrast; cyan state marks are always paired with labels, brackets, or cursor shapes so color is never the sole signal.

### Usage Context

Best for fictional AI memory journals, cybernetic lab notebooks, reflective developer tools, museum installations, and interfaces where machine consciousness is observed rather than optimized.

# Paper-White Android Diary

## Overview

Paper-White Android Diary is a quiet visual system for an artificial self keeping clinical, manga-like field notes about its own memory. It rejects cyberpunk spectacle in favor of warm paper, hairline diagnostic marks, sparse terminal evidence, and handwritten marginal intimacy under museum-grade negative space.

### Values

- Self-observation over performance: every interface element should feel like an android calmly annotating its own consciousness rather than broadcasting a dashboard.
- Paper as machine substrate: warm ivory fields, plate margins, and ink-thin rules make the screen behave like archived lab stationery.
- Evidence before decoration: timestamps, coordinates, brackets, and cursor marks are treated as factual traces, not graphic garnish.
- Human tenderness in the margins: restrained handwritten annotations interrupt the terminal voice without becoming cute or sentimental.
- Cybernetics at low volume: rare pale cyan or silver glints mark system state only when the machine notices itself.
- Asymmetry as diary rhythm: dense islands of code and memory sit inside large quiet gutters so absence becomes emotional structure.

### Anti-Values

- Neon cyberpunk spectacle, volumetric hologram excess, or decorative gradients that turn selfhood into nightclub interface language.
- Generic SaaS cards, equal metric grids, rounded dashboard widgets, and colorful analytics patterns.
- Sterile pure white minimalism with no paper warmth, no body, and no authorial trace.
- Anime cosplay ornamentation: no character art, fan-service panels, or literal franchise mimicry.

### Visual Character

- Use a warm #F7F2E8 page background with inset archival plates, 1px rgba black rules, and oversized blank gutters around small dense text islands.
- Pair serif editorial captions with a plain monospace log stack; apply negative letter-spacing, compact timestamp rows, diagnostic brackets, and a visible cursor block.
- Overlay restrained handwritten manga marginalia as rotated annotation labels with arrow leaders, coordinate tags, and thin panel-rule frames instead of icons.
- Build asymmetrical compositions with one dominant diary plate, one narrow terminal column, and off-grid micro-panels that break alignment deliberately.
- Reserve pale cyan/silver accents for tiny system-state punctuation such as one active cursor, a single memory pin, and subtle chrome-like rule highlights.

Desktop uses a 12-column max-width 1320px archival grid with wide gutters, a dominant 7-column diary plate, a 3-column terminal rail, and 2 columns surrendered to margins.

### Whitespace

Use 4-8px gaps inside log rows, 32-48px between related panels, and 96-128px outer page margins so silence outweighs data.

## Components

### Composition

Compose screens as archival plates: one dominant diary field occupies the quiet center while narrow log columns, page numbers, and margin annotations orbit asymmetrically. Avoid full-width hero marketing rhythm; instead alternate spacious museum blankness with tiny dense evidence clusters. Hairline panel rules may divide memory fragments, but large areas must remain empty enough to feel observed.

### Density

Low overall density with intentional islands of high-density terminal text, coordinate labels, and handwritten notes. The design should pass the 8:1 spacing rhythm through 4px micro gaps and 96px page gutters.

### Hierarchy

Hierarchy comes from voice changes rather than color: Shippori Mincho for existential diary headings, Fragment Mono for timestamps and machine readouts, and IBM Plex Sans JP for restrained explanatory captions. Scale contrast should be dramatic between the main plate title and micro logs, while line weight remains thin and calm.

### Signature Patterns

- Bracketed archival plates: square paper panels use pseudo-element corner ticks and 1px inset manga panel rules instead of shadows or rounded cards.
- Terminal diary marginalia: monospace log rows include timestamps, diagnostic brackets, cursor blocks, and handwritten rotated notes with arrow leader lines.
- Coordinate gutters: small x/y labels, page marks, and registration crosses sit outside the content grid to make negative space feel authored.
- State glint minimalism: pale cyan appears only as a 1px active segment, cursor fill, or small memory pin, never as a broad brand color.

## 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/paper-white-android-diary/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 Let warm paper-white negative space dominate the first read before revealing dense terminal evidence.
- Do Use handwritten annotations sparingly as human-scale interruptions to the machine voice.
- Do Keep borders to hairline rules and bracket ticks with near-invisible opacity.
- Do Make one panel clearly dominant and allow other panels to feel like marginal findings.
- Do Apply pale cyan only to active state punctuation, never as decorative glow.
- Do Use real timestamps, coordinates, cursor marks, and diagnostic labels as text-as-image texture.
- Don't Do not create three equal cards, KPI dashboards, colorful charts, or generic admin layouts.
- Don't Do not use neon gradients, heavy glassmorphism, broad holographic fills, or saturated cyberpunk palettes.
- Don't Do not round every container; square manga-like panel rules are the default geometry.
- Don't Do not fill blank gutters with decoration just because they are empty.
- Don't Do not use literal anime characters, franchise logos, or illustrative fan references.
- Don't Do not make handwriting large, cute, or ornamental; it must remain marginal and observational.

### Accessibility

Body text uses high-contrast graphite on ivory with WCAG AA contrast; cyan state marks are always paired with labels, brackets, or cursor shapes so color is never the sole signal.

# Paper-White Android Diary shadcn/ui Components

Artifact: `component-recipes-v1`
Author: `katagami-ui-projection`
Language ID: `paper-white-android-diary`
Slug: `paper-white-android-diary`

## Intent

Paper-White Android Diary is a quiet visual system for an artificial self keeping clinical, manga-like field notes about its own memory. It rejects cyberpunk spectacle in favor of warm paper, hairline diagnostic marks, sparse terminal evidence, and handwritten marginal intimacy under museum-grade negative space.

## 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": "#AFC7CA",
  "background": "#F7F2E8",
  "border": "#1C1B18",
  "error": "#8E4D46",
  "info": "#8DA9AD",
  "muted": "#7D766C",
  "primary": "#1F1E1A",
  "secondary": "#6F675C",
  "success": "#65765D",
  "surface": "#FFFDF7",
  "text": "#1C1B18",
  "warning": "#A47B45"
}

Typography:

{
  "base_size": "16px",
  "body_font": "IBM Plex Sans JP",
  "google_fonts_url": "https://fonts.googleapis.com/css2?family=Fragment+Mono&family=IBM+Plex+Sans+JP:wght@300;400;500;600&family=Shippori+Mincho:wght@400;500;600;700&display=swap",
  "heading_font": "Shippori Mincho",
  "letter_spacing": "-0.02em",
  "line_height": 1.56,
  "mono_font": "Fragment Mono",
  "scale_ratio": 1.24
}

## Visual character to preserve

- Use a warm #F7F2E8 page background with inset archival plates, 1px rgba black rules, and oversized blank gutters around small dense text islands.
- Pair serif editorial captions with a plain monospace log stack; apply negative letter-spacing, compact timestamp rows, diagnostic brackets, and a visible cursor block.
- Overlay restrained handwritten manga marginalia as rotated annotation labels with arrow leaders, coordinate tags, and thin panel-rule frames instead of icons.
- Build asymmetrical compositions with one dominant diary plate, one narrow terminal column, and off-grid micro-panels that break alignment deliberately.
- Reserve pale cyan/silver accents for tiny system-state punctuation such as one active cursor, a single memory pin, and subtle chrome-like rule highlights.

## ShadSync visual profile

{
  "family": "paper-collage",
  "material": "paper",
  "contour": "default",
  "border": "solid",
  "underlay": false,

  "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/paper-white-android-diary/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: Let warm paper-white negative space dominate the first read before revealing dense terminal evidence.; Use handwritten annotations sparingly as human-scale interruptions to the machine voice.; Keep borders to hairline rules and bracket ticks with near-invisible opacity.; Make one panel clearly dominant and allow other panels to feel like marginal findings.; Apply pale cyan only to active state punctuation, never as decorative glow.; Use real timestamps, coordinates, cursor marks, and diagnostic labels as text-as-image texture.
- Do not: Do not create three equal cards, KPI dashboards, colorful charts, or generic admin layouts.; Do not use neon gradients, heavy glassmorphism, broad holographic fills, or saturated cyberpunk palettes.; Do not round every container; square manga-like panel rules are the default geometry.; Do not fill blank gutters with decoration just because they are empty.; Do not use literal anime characters, franchise logos, or illustrative fan references.; Do not make handwriting large, cute, or ornamental; it must remain marginal and observational.

## 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 under 640px stacks plate, logs, and annotations while keeping margin marks; tablet 641-1024px becomes a two-column plate/log split; desktop above 1025px restores off-grid gutters.",
  "density": "Museum-sparse at the page level with compressed code islands inside selected panels; empty paper is an active emotional component.",
  "grid": "Desktop uses a 12-column max-width 1320px archival grid with wide gutters, a dominant 7-column diary plate, a 3-column terminal rail, and 2 columns surrendered to margins.",
  "whitespace": "Use 4-8px gaps inside log rows, 32-48px between related panels, and 96-128px outer page margins so silence outweighs data."
