## Philosophy

A quiet clinical e-paper language for neural-map manuals: warm bone surfaces, carbon graphite hairlines, calibration ticks, erased-memory voids, and a single cyan registration mark on the one node under probe. The faithful, brought-to-standard edition of E-Ink Neurography Manuals.

### Values

- clinical restraint over spectacle
- evidence-first hierarchy — state and labels beat marketing copy
- large quiet specimen fields with precise instrument density
- manga-structural schematic linework, never character art
- machine intimacy expressed through labels, gaps, and calibration marks

### Anti-Values

- no green matrix rain or hacker-dashboard motifs
- no neon cyberpunk gradients or decorative glow
- no equal SaaS card grids
- no full-character anime posters
- no borders, accent edges, or grey-washed surfaces

### Radii

- **Base**: 0px
- **Scanner Pane**: 16px
- **Pill**: 9999px

### Shadows

- **Sm**: 0 1px 2px rgba(21,23,26,.06)
- **Md**: 0 10px 26px rgba(21,23,26,.08)
- **Lg**: 0 24px 56px rgba(21,23,26,.12)

### Spacing

- **Base**: 4px
- **Scale**: ["4px","8px","12px","16px","24px","36px","56px","72px"]

### Surfaces

- **Paper**: warm bone e-paper #F4F1E8 with subtle grain
- **Panel**: paler bone #FBFAF4 instrument panels lifted by soft flat shadow
- **Recess**: #ECE8DC inset for form controls
- **Erased Void**: dashed graphite outline over rubbed #E3DFD1 hatch

### Borders

- **Policy**: none — separate by space, the 24px annotation grid, recessed surface, and soft shadow; no card border or accent edge

### Motion

- **Refresh**: 180ms steps(2,end) e-ink ghost shift
- **Calibration**: 260ms ease-out tick drift, max 2px
- **Reveal**: 0.7s ease intersection reveal, gated behind .anim; settled state visible with no JS
- **Reduced Motion**: respected — settled state is the default

## Rules

### Composition

Build one dominant quiet specimen field, one dense instrument cluster, and one marginal evidence rail. Avoid equal card rows.

### Hierarchy

Operational state and evidence labels beat marketing copy. Cyan marks state, exception, or proof only.

### Density

Alternate sparse archival whitespace with compressed 4px-8px annotation systems.

### Signature

A graphite contour plate with a single cyan registration bracket on the active node; calibration tick rulers, e-paper refresh ghosts, and erased-memory voids recur as structure.

## Layout

### Grid

12-column desktop with a dominant specimen pane plus a narrow evidence rail and manual margins

### Whitespace

preserve large blanks as clinical silence; always pad above titles

### Density

dense labels only at decision points

### Responsive

desktop keeps the specimen pane + right rail; tablet stacks rails below; mobile collapses to single-column diagnostic sheets, hides non-essential columns, never overflows

### Breakpoints

- **Mobile**: 390px
- **Tablet**: 760px
- **Desktop**: 1100px
- **Ultrawide**: 1700px

## Guidance

### Do

- Use pale material restraint: warm bone surfaces, graphite ink, faint scanner-gray grid rules.
- Write labels as diagnostic evidence: coordinates, thresholds, hashes, specimen states, proof stamps.
- Keep cyan semantic for the active probe, exception pixels, focus rings, and registration marks.
- Use linework, ruler ticks, leader lines, and contour diagrams as structure rather than decoration.

### Don't

- Do not use green matrix rain, terminal walls, or generic hacker-dashboard motifs.
- Do not build equal SaaS card grids; preserve one dominant specimen field and marginal rails.
- Do not use neon cyberpunk gradients, decorative glow, or saturated rainbow accents.
- Do not include full-character anime posters or fan-art imagery; keep manga influence schematic.
- Do not add borders, accent edges, or grey-washed surfaces.

### Accessibility

Body 17px+ with high contrast carbon-on-bone; cyan reserved for state with a non-colour cue (bracket / label) alongside; settled state visible with no JavaScript; motion respects prefers-reduced-motion; form controls explicitly styled with visible focus.

## Imagery Direction

### Pairs With

graphite-schematic

### Summary

Monochrome graphite schematic linework on warm bone e-paper: cropped instruments, neural-map contours, and abstract anatomy drawn like a printed field manual, with one restrained cyan registration mark.

### Subjects

- neuron and axon contour maps
- cross-sectioned anatomy
- cropped instrument panels
- calibration plates
- memory-map diagrams

### Usage

Generate hero and feature imagery as full-frame graphite survey plates; keep cyan to a single registration bracket; never render the medium itself; no text.

## 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-019ef751-7c41-7df1-b7d7-9315eeb850f6/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 pale material restraint: warm bone surfaces, graphite ink, faint scanner-gray grid rules.
- Do Write labels as diagnostic evidence: coordinates, thresholds, hashes, specimen states, proof stamps.
- Do Keep cyan semantic for the active probe, exception pixels, focus rings, and registration marks.
- Do Use linework, ruler ticks, leader lines, and contour diagrams as structure rather than decoration.
- Don't Do not use green matrix rain, terminal walls, or generic hacker-dashboard motifs.
- Don't Do not build equal SaaS card grids; preserve one dominant specimen field and marginal rails.
- Don't Do not use neon cyberpunk gradients, decorative glow, or saturated rainbow accents.
- Don't Do not include full-character anime posters or fan-art imagery; keep manga influence schematic.
- Don't Do not add borders, accent edges, or grey-washed surfaces.

### Accessibility

Body 17px+ with high contrast carbon-on-bone; cyan reserved for state with a non-colour cue (bracket / label) alongside; settled state visible with no JavaScript; motion respects prefers-reduced-motion; form controls explicitly styled with visible focus.

## Imagery Direction
