summary
Lineplate Atelier translates the tension of editorial ink drawing into a digital fine-art workspace: precise black linework, pressure-sensitive marks, stippled atmospheres, and sparse luminous overlays behave like curated interventions rather than decorative effects.
values
Drawing remains the primary medium; every surface should feel constructed from line, hatch, brush drag, and negative space.Digital enhancement is treated as institutional new-media lighting: controlled, documented, and secondary to the ink foundation.Editorial clarity matters; captions, metadata, and specimen records create a serious art-publication rhythm.Contrast is structural, using black rules and off-white paper fields before relying on color.Imperfection is preserved through grain, irregular edge masks, and handmade brush texture inside disciplined grids.Interfaces should feel like a plate proofing table where curators compare marks, editions, and digital overlays.
anti-values
×No glossy gradient spectacle, rainbow cyber surfaces, or generic futurist neon unrelated to the ink system.×No soft SaaS cards, rounded dashboard sameness, or default browser controls that erase the editorial print lineage.×No ornamental illustration pasted on top; linework must organize layout, hierarchy, and interaction states.×No low-contrast gray minimalism that weakens the black-and-paper discipline.

rules
composition
Use an editorial proofing grid: a left curatorial rail, a central artwork plate, and a right metadata column on desktop. Align actions to caption rules rather than floating them in generic cards. Crop marks and plate labels should frame content, while mobile collapses into stacked proof sheets with the rail becoming a top index.
hierarchy
Lead with large condensed serif plate titles, then smaller serif dek text, then mono metadata labels. Buttons and form labels use mono uppercase for institutional precision. Artwork titles and table entries keep generous line-height so dense ink texture does not crowd the reading surface.
density
Medium-high editorial density is acceptable when divided by rules, marginal notes, and negative paper gutters; never pack controls without a caption or plate boundary.
signature patterns
Crosshatch fields are built with two opposing repeating-linear-gradients clipped to panels and page background.Artwork and modal surfaces use stipple-dot radial gradients plus a brush-smear pseudo-element as controlled digital mixed media texture.Interactive focus states add vermilion rule shifts and a thin cyan-violet glow that reads as a digital overlay registration layer.Cards carry crop-mark corner pseudo-elements and offset black registration shadows instead of soft elevation.Tables and accordions use numbered plate gutters, vertical captions, and interrupted ink rules to preserve editorial illustration structure.
layout
density

Medium-high density with proofing-room discipline: details are visible, but every cluster has a rule, caption, or paper gutter to maintain legibility.

grid

Desktop uses a 12-column max-width 1380px grid with 24px gutters: 2 columns for index, 7 for the artwork plate, 3 for metadata and actions.

breakpoints

1440px full proofing desk, 900px two-column tablet with metadata below plate, 640px single-column mobile with horizontal tab navigation and stacked panels.

whitespace

Whitespace acts like unprinted paper margins; keep 24-48px gutters around major plates and smaller 8-12px intervals inside caption mechanics.

responsive
At tablet width the right rail moves below the plate and dense tables scroll horizontally. At mobile width crop marks shrink, captions become top labels, and controls stack with full-width touch targets.
guidance
do
  • Use black linework, hatching, stippling, and brush texture as structural layout devices.
  • Keep accent color scarce: vermilion for selection or warning, luminous cyan-violet only for digital layer inspection.
  • Write UI copy like an editorial art catalog with plate numbers, edition metadata, and curatorial notes.
  • Style every form control with hard ink borders, mono labels, and clear focus states.
  • Use zero-radius panels and offset registration shadows consistently across cards, modals, and alerts.
  • Let negative paper space separate dense information rather than relying on pale gray dividers.
avoid
  • Do not use generic dashboard cards, pill-heavy SaaS controls, or arbitrary rounded corners.
  • Do not make gradients the main identity; they must appear as small digital fine-art interventions.
  • Do not flatten the ink textures into decorative backgrounds that ignore hierarchy.
  • Do not combine many accent colors or allow neon to overpower monochrome drawing foundations.
  • Do not leave native selects, checkboxes, radios, or inputs unstyled.
  • Do not crowd mobile screens with three-column proofing logic; recompose the editorial stack.

## Philosophy

Lineplate Atelier translates the tension of editorial ink drawing into a digital fine-art workspace: precise black linework, pressure-sensitive marks, stippled atmospheres, and sparse luminous overlays behave like curated interventions rather than decorative effects.

### Values

- Drawing remains the primary medium; every surface should feel constructed from line, hatch, brush drag, and negative space.
- Digital enhancement is treated as institutional new-media lighting: controlled, documented, and secondary to the ink foundation.
- Editorial clarity matters; captions, metadata, and specimen records create a serious art-publication rhythm.
- Contrast is structural, using black rules and off-white paper fields before relying on color.
- Imperfection is preserved through grain, irregular edge masks, and handmade brush texture inside disciplined grids.
- Interfaces should feel like a plate proofing table where curators compare marks, editions, and digital overlays.

### Anti-Values

- No glossy gradient spectacle, rainbow cyber surfaces, or generic futurist neon unrelated to the ink system.
- No soft SaaS cards, rounded dashboard sameness, or default browser controls that erase the editorial print lineage.
- No ornamental illustration pasted on top; linework must organize layout, hierarchy, and interaction states.
- No low-contrast gray minimalism that weakens the black-and-paper discipline.

### Visual Character

- Use hard rectangular paper panels with zero-radius corners, double-rule borders, and offset black registration shadows.
- Build backgrounds from layered CSS hatching, stipple radial dots, and brush-grain masks rather than flat fills.
- Set compressed editorial serif headings against calm humanist sans body text with tight tracking and plate-number metadata.
- Reserve one restrained vermilion accent and occasional cyan-violet digital glows for active states and artwork overlays.
- Segment dense UI with vertical figure labels, caption rules, and marginal notes that mimic gallery catalog annotations.

### Usage Context

Best for digital fine-art archives, editorial illustration review tools, gallery publishing systems, new-media acquisition boards, and mixed-media proofing workflows.

### Accessibility

Maintain AA contrast through dark ink text on warm paper, visible keyboard focus using vermilion plus glow, semantic buttons and labels, and texture opacity low enough not to disrupt reading.

# Lineplate Atelier

## Overview

Lineplate Atelier translates the tension of editorial ink drawing into a digital fine-art workspace: precise black linework, pressure-sensitive marks, stippled atmospheres, and sparse luminous overlays behave like curated interventions rather than decorative effects.

### Values

- Drawing remains the primary medium; every surface should feel constructed from line, hatch, brush drag, and negative space.
- Digital enhancement is treated as institutional new-media lighting: controlled, documented, and secondary to the ink foundation.
- Editorial clarity matters; captions, metadata, and specimen records create a serious art-publication rhythm.
- Contrast is structural, using black rules and off-white paper fields before relying on color.
- Imperfection is preserved through grain, irregular edge masks, and handmade brush texture inside disciplined grids.
- Interfaces should feel like a plate proofing table where curators compare marks, editions, and digital overlays.

### Anti-Values

- No glossy gradient spectacle, rainbow cyber surfaces, or generic futurist neon unrelated to the ink system.
- No soft SaaS cards, rounded dashboard sameness, or default browser controls that erase the editorial print lineage.
- No ornamental illustration pasted on top; linework must organize layout, hierarchy, and interaction states.
- No low-contrast gray minimalism that weakens the black-and-paper discipline.

### Visual Character

- Use hard rectangular paper panels with zero-radius corners, double-rule borders, and offset black registration shadows.
- Build backgrounds from layered CSS hatching, stipple radial dots, and brush-grain masks rather than flat fills.
- Set compressed editorial serif headings against calm humanist sans body text with tight tracking and plate-number metadata.
- Reserve one restrained vermilion accent and occasional cyan-violet digital glows for active states and artwork overlays.
- Segment dense UI with vertical figure labels, caption rules, and marginal notes that mimic gallery catalog annotations.

### Density

Medium-high density with proofing-room discipline: details are visible, but every cluster has a rule, caption, or paper gutter to maintain legibility.

### Grid

Desktop uses a 12-column max-width 1380px grid with 24px gutters: 2 columns for index, 7 for the artwork plate, 3 for metadata and actions.

### Breakpoints

1440px full proofing desk, 900px two-column tablet with metadata below plate, 640px single-column mobile with horizontal tab navigation and stacked panels.

### Whitespace

Whitespace acts like unprinted paper margins; keep 24-48px gutters around major plates and smaller 8-12px intervals inside caption mechanics.

### Responsive

At tablet width the right rail moves below the plate and dense tables scroll horizontally. At mobile width crop marks shrink, captions become top labels, and controls stack with full-width touch targets.

### Surfaces

- **Treatment**: Warm paper grounds with fine repeating hatch lines, stippled dot veils, and masked brush-smudge overlays at low opacity.
- **Card Style**: Sharp-corner proof cards with double borders, inner caption rails, and offset registration shadows.
- **Bg Pattern**: Cross-hatched linear gradients layered with sparse radial stipple dots and one restrained luminous overlay per composition.

### Borders

- **Default Width**: 1px
- **Accent Width**: 3px
- **Style**: solid plus inset double-rule construction
- **Character**: Ink-black editorial rules, crop marks, registration ticks, and interrupted caption dividers.

## Components

### Composition

Use an editorial proofing grid: a left curatorial rail, a central artwork plate, and a right metadata column on desktop. Align actions to caption rules rather than floating them in generic cards. Crop marks and plate labels should frame content, while mobile collapses into stacked proof sheets with the rail becoming a top index.

### Hierarchy

Lead with large condensed serif plate titles, then smaller serif dek text, then mono metadata labels. Buttons and form labels use mono uppercase for institutional precision. Artwork titles and table entries keep generous line-height so dense ink texture does not crowd the reading surface.

### Density

Medium-high editorial density is acceptable when divided by rules, marginal notes, and negative paper gutters; never pack controls without a caption or plate boundary.

### Signature Patterns

- Crosshatch fields are built with two opposing repeating-linear-gradients clipped to panels and page background.
- Artwork and modal surfaces use stipple-dot radial gradients plus a brush-smear pseudo-element as controlled digital mixed media texture.
- Interactive focus states add vermilion rule shifts and a thin cyan-violet glow that reads as a digital overlay registration layer.
- Cards carry crop-mark corner pseudo-elements and offset black registration shadows instead of soft elevation.
- Tables and accordions use numbered plate gutters, vertical captions, and interrupted ink rules to preserve editorial illustration structure.

## 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-019ddbdd-1766-76e1-b4ba-ff129d11637e/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 black linework, hatching, stippling, and brush texture as structural layout devices.
- Do Keep accent color scarce: vermilion for selection or warning, luminous cyan-violet only for digital layer inspection.
- Do Write UI copy like an editorial art catalog with plate numbers, edition metadata, and curatorial notes.
- Do Style every form control with hard ink borders, mono labels, and clear focus states.
- Do Use zero-radius panels and offset registration shadows consistently across cards, modals, and alerts.
- Do Let negative paper space separate dense information rather than relying on pale gray dividers.
- Don't Do not use generic dashboard cards, pill-heavy SaaS controls, or arbitrary rounded corners.
- Don't Do not make gradients the main identity; they must appear as small digital fine-art interventions.
- Don't Do not flatten the ink textures into decorative backgrounds that ignore hierarchy.
- Don't Do not combine many accent colors or allow neon to overpower monochrome drawing foundations.
- Don't Do not leave native selects, checkboxes, radios, or inputs unstyled.
- Don't Do not crowd mobile screens with three-column proofing logic; recompose the editorial stack.

### Usage Context

Best for digital fine-art archives, editorial illustration review tools, gallery publishing systems, new-media acquisition boards, and mixed-media proofing workflows.

### Accessibility

Maintain AA contrast through dark ink text on warm paper, visible keyboard focus using vermilion plus glow, semantic buttons and labels, and texture opacity low enough not to disrupt reading.

# Lineplate Atelier shadcn/ui Components

Artifact: `component-recipes-v1`
Author: `katagami-ui-projection`
Language ID: `en-019ddbdd-1766-76e1-b4ba-ff129d11637e`
Slug: `lineplate-atelier`

## Intent

Lineplate Atelier translates the tension of editorial ink drawing into a digital fine-art workspace: precise black linework, pressure-sensitive marks, stippled atmospheres, and sparse luminous overlays behave like curated interventions rather than decorative effects.

## 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:

{
  "primary": "#11100E",
  "secondary": "#F2EBDD",
  "accent": "#B33524",
  "background": "#E8DDC9",
  "surface": "#FFF8E8",
  "text": "#14110D",
  "muted": "#6D6253",
  "border": "#201B16",
  "error": "#9B1C1C",
  "success": "#2F6B45",
  "warning": "#A66A12",
  "info": "#365C8D"
}

Typography:

{
  "heading_font": "Libre Caslon Condensed",
  "body_font": "Newsreader",
  "mono_font": "IBM Plex Mono",
  "base_size": "16px",
  "scale_ratio": 1.22,
  "line_height": 1.52,
  "letter_spacing": "-0.02em",
  "google_fonts_url": "https://fonts.googleapis.com/css2?family=IBM+Plex+Mono:wght@400;500;600&family=Libre+Caslon+Condensed:wght@400;600;700&family=Newsreader:opsz,wght@6..72,400;6..72,500;6..72,700&display=swap"
}

## Visual character to preserve

- Use hard rectangular paper panels with zero-radius corners, double-rule borders, and offset black registration shadows.
- Build backgrounds from layered CSS hatching, stipple radial dots, and brush-grain masks rather than flat fills.
- Set compressed editorial serif headings against calm humanist sans body text with tight tracking and plate-number metadata.
- Reserve one restrained vermilion accent and occasional cyan-violet digital glows for active states and artwork overlays.
- Segment dense UI with vertical figure labels, caption rules, and marginal notes that mimic gallery catalog annotations.

## ShadSync visual profile

{
  "family": "paper-collage",
  "material": "paper",
  "contour": "default",
  "border": "solid",
  "underlay": true,
  "grain": true,
  "stickerBadges": false,
  "motion": "lift",
  "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/lineplate-atelier/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 black linework, hatching, stippling, and brush texture as structural layout devices.; Keep accent color scarce: vermilion for selection or warning, luminous cyan-violet only for digital layer inspection.; Write UI copy like an editorial art catalog with plate numbers, edition metadata, and curatorial notes.; Style every form control with hard ink borders, mono labels, and clear focus states.; Use zero-radius panels and offset registration shadows consistently across cards, modals, and alerts.; Let negative paper space separate dense information rather than relying on pale gray dividers.
- Do not: Do not use generic dashboard cards, pill-heavy SaaS controls, or arbitrary rounded corners.; Do not make gradients the main identity; they must appear as small digital fine-art interventions.; Do not flatten the ink textures into decorative backgrounds that ignore hierarchy.; Do not combine many accent colors or allow neon to overpower monochrome drawing foundations.; Do not leave native selects, checkboxes, radios, or inputs unstyled.; Do not crowd mobile screens with three-column proofing logic; recompose the editorial stack.

## 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

{
  "density": "Medium-high density with proofing-room discipline: details are visible, but every cluster has a rule, caption, or paper gutter to maintain legibility.",
  "grid": "Desktop uses a 12-column max-width 1380px grid with 24px gutters: 2 columns for index, 7 for the artwork plate, 3 for metadata and actions.",
  "breakpoints": "1440px full proofing desk, 900px two-column tablet with metadata below plate, 640px single-column mobile with horizontal tab navigation and stacked panels.",
  "whitespace": "Whitespace acts like unprinted paper margins; keep 24-48px gutters around major plates and smaller 8-12px intervals inside caption mechanics.",
  "responsive": "At tablet width the right rail moves below the plate and dense tables scroll horizontally. At mobile width crop marks shrink, captions become top labels, and controls stack with full-width touch targets."
