rules
composition

Compose screens like archival medical plates: dominant negative space, one primary diagnostic specimen, and peripheral metadata rails for operator context.

density

Low to medium density with compact readouts clustered in calibrated bands and broad quiet paper margins around the specimen.

hierarchy

Hierarchy comes from ruled labels, type weight, scale, and proximity; cyan appears only when a memory artifact or alarm exception needs attention.

signature patterns
Calibration corners use absolute-positioned crop marks and tiny baseline ticks around every major plate.Neurographic maps use thin SVG polylines, open circles, numeric callouts, and a single cyan filled node for evidence.Command strips mimic shell manuals with prompt arrows, bracketed flags, and ruled output rows instead of pill buttons.Alarm hierarchy is rendered as monochrome labels first, with cyan or muted red reserved for exceptional evidence states only.
layout
breakpoints

mobile 375px single-column stacked plates; tablet 768px two-band layout; desktop 1200px+ specimen plus right diagnostic rail

grid

12-column archival grid with a wide specimen field and narrow operator rail; modules snap to 8px calibration units.

whitespace

Large paper margins are functional breathing room; avoid filling empty space unless the operator needs comparison data.

guidance
do
  • Use paper-white, bone, graphite, and scanner gray as the default interface material.
  • Represent data as labeled traces, ruled rows, evidence pixels, and clinical captions.
  • Keep motion nearly absent and make all state changes readable in a static screenshot.
  • Let sparse cyan carry forensic or exception meaning, not brand decoration.
avoid
  • Do not use green matrix rain, neon cyberpunk palettes, or decorative glow.
  • Do not make generic rounded SaaS cards or marketing dashboards.
  • Do not add character art, fan-art manga faces, or illustrative scenes.
  • Do not depend on hover animation or color alone for comprehension.

# E-Ink Neurography Manuals

## Philosophy

E-Ink Neurography Manuals treats product interfaces as cold archival diagnostic plates for post-human medical consoles: pale optical surfaces, graphite neurographic routes, scanner calibration marks, and rare cyan memory pixels that appear only as evidence or exception state.

### Values

- legibility over motion
- clinical restraint
- operator task performance
- forensic traceability
- high negative space

### Anti-Values

- green matrix rain
- generic hacker dashboards
- neon cyberpunk glow
- SaaS card decoration
- character fan-art illustration

### Visual Character

- Paper-white full-bleed shell with hairline graphite borders, crop marks, registration ticks, and no decorative gradients or glow.
- Two-column diagnostic plate grid with sparse modules separated by calibration gutters rather than rounded SaaS cards.
- Neurographic SVG pathways drawn as thin graphite polylines with small numbered nodes and cyan pixels reserved for confirmed memory artifacts.
- Manual-style captions, command labels, and monospaced readouts aligned to scanner-gray baselines with compact uppercase metadata.

## 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/e-ink-neurography-manuals/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.

# E-Ink Neurography Manuals shadcn/ui Components

Artifact: `component-recipes-v1`
Author: `katagami-ui-projection`
Language ID: `e-ink-neurography-manuals`
Slug: `e-ink-neurography-manuals`

## Intent

E-Ink Neurography Manuals treats product interfaces as cold archival diagnostic plates for post-human medical consoles: pale optical surfaces, graphite neurographic routes, scanner calibration marks, and rare cyan memory pixels that appear only as evidence or exception state.

## 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": "#58D7E8",
  "background": "#FBFAF5",
  "border": "#B9C0C2",
  "error": "#B54A42",
  "info": "#58D7E8",
  "muted": "#7B8182",
  "primary": "#1D1E1C",
  "secondary": "#6D7475",
  "success": "#5B7565",
  "surface": "#F4F7F7",
  "text": "#1D1E1C",
  "warning": "#B08A3C"
}

Typography:

{
  "base_size": "16px",
  "body_font": "IBM Plex Serif",
  "google_fonts_url": "https://fonts.googleapis.com/css2?family=IBM+Plex+Mono:wght@400;500;600&family=IBM+Plex+Sans+Condensed:wght@500;600;700&family=IBM+Plex+Serif:wght@400;500;600&display=swap",
  "heading_font": "IBM Plex Sans Condensed",
  "letter_spacing": "-0.012em",
  "line_height": 1.48,
  "mono_font": "IBM Plex Mono",
  "scale_ratio": 1.2
}

## Visual character to preserve

- Paper-white full-bleed shell with hairline graphite borders, crop marks, registration ticks, and no decorative gradients or glow.
- Two-column diagnostic plate grid with sparse modules separated by calibration gutters rather than rounded SaaS cards.
- Neurographic SVG pathways drawn as thin graphite polylines with small numbered nodes and cyan pixels reserved for confirmed memory artifacts.
- Manual-style captions, command labels, and monospaced readouts aligned to scanner-gray baselines with compact uppercase metadata.

## ShadSync visual profile

  "family": "paper-collage",
  "material": "paper",
  "contour": "pebble",

  "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/e-ink-neurography-manuals/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 paper-white, bone, graphite, and scanner gray as the default interface material.; Represent data as labeled traces, ruled rows, evidence pixels, and clinical captions.; Keep motion nearly absent and make all state changes readable in a static screenshot.; Let sparse cyan carry forensic or exception meaning, not brand decoration.
- Do not: Do not use green matrix rain, neon cyberpunk palettes, or decorative glow.; Do not make generic rounded SaaS cards or marketing dashboards.; Do not add character art, fan-art manga faces, or illustrative scenes.; Do not depend on hover animation or color alone for comprehension.

## Copy-paste component example
