rules
composition
Use catalogue-spread asymmetry: one dominant record, one narrow taxonomy rail, one open paper field, and a few dense annotation clusters. Keep full-width moments rare, vary section weight, and let dry-brush rules define reading direction instead of boxy dashboards.
density

Overall density is low to medium: spacious paper fields dominate, but archive rows and provenance tables can become compact when adjacent to a large quiet void.

hierarchy
Display hierarchy comes from scale, empty field, and metadata precision: large serif title at 56-88px desktop, small uppercase mono accessions, 16px body annotations, and seal-red marks only for verified authorship or selected states.
signature patterns
A pressure rail uses layered linear-gradients with variable thickness and opacity to mimic dry-to-wet brush force along a metadata column.Catalogue plates carry xuan-fiber texture through pseudo-elements combining repeating-linear-gradients and radial ink blooms clipped to the surface.Vermilion seal squares are semantic UI punctuation: selected object, verified provenance, or authorship marker, never a decorative icon set.Object records use an asymmetric void grid where the artwork silhouette sits off-center and captions align to narrow scholarly rails.Hover and focus states deepen ink halos and sharpen accession labels, suggesting absorption and attention without adding new colors.
layout
breakpoints

mobile <= 640px, tablet 641px-1024px, desktop >= 1025px; rails collapse above content on mobile and plates stack with preserved void margins.

density

Low-density primary screens with dense scholarly clusters only in rails, footnotes, accession lists, and filter taxonomies.

grid

Desktop uses a 14-column grid: 2 columns for collection rail, 7 for dominant plate/void, 3 for annotations, and 2 held empty; gutters 24px, max-width 1520px.

responsive
At tablet widths the annotation rail moves below the hero plate; at mobile widths seal marks remain small, brush rails become horizontal, and long headings wrap at 1.1 line-height.
whitespace
Whitespace is a material field, not leftover space: 4-12px inside metadata clusters, 48-128px between interpretive sections, and deliberately blank plate areas around artwork records.
guidance
do
  • Use warm paper whites and layered ink blacks, with texture subtle enough that long scholarly text remains readable.
  • Reserve vermilion for provenance, authorship, active selection, or critical annotation markers only.
  • Build layouts around one dominant catalogue object and at least one large quiet negative field.
  • Represent brush pressure through CSS stroke structure, irregular rules, opacity, and edge behavior rather than literal calligraphy decoration.
  • Pair object titles, dynasty/artist metadata, medium, accession numbers, and interpretive notes like a credible museum archive.
  • Keep corners mostly square, borders hairline-light, and shadows soft enough to read as paper lift rather than app chrome.
  • Use mono labels for accession and taxonomy codes to distinguish scholarship from interpretive prose.
  • Maintain accessible contrast by placing all body copy on calmer paper surfaces, not over heavy ink blooms.
avoid
  • Do not use bamboo, dragons, lanterns, fans, chopstick imagery, or generic red-circle Asian branding.
  • Do not use brush-script fonts or fake handwritten titles to imply calligraphy.
  • Do not make red a broad brand color; repeated red buttons or red borders cheapen the seal logic.
  • Do not fill the screen with equal cards or analytics widgets; this is an archive and catalogue system, not a dashboard.
  • Do not use high-saturation neon accents, glossy gradients, or friendly rounded SaaS components.
  • Do not let texture become grunge; xuan fibers should be almost tactile, not dirty.
  • Do not center every element; disciplined off-center placement is part of the ink composition.
  • Do not flatten all records into uniform list rows when a featured plate needs slow looking time.

## Philosophy

A scholarly gallery interface language for contemporary Chinese ink and calligraphic abstraction, translating brush pressure, xuan-paper absorption, seal discipline, and catalogue scholarship into a quiet production-ready product system. It treats ink as evidence of force and time rather than decoration: wide paper fields, dry-to-wet tonal layers, measured archive metadata, and a single vermilion provenance mark organize the experience without resorting to tourist calligraphy or generic East Asian motifs.

### Values

- material specificity: xuan-paper fibers, ink absorption, pressure variation, and dry brush edges become structural UI decisions
- scholarly restraint with enough expressive gesture to feel like contemporary art rather than a sterile database
- negative space as active composition, giving each object record room to breathe like an album leaf or catalogue plate
- seal vermilion used only for authorship, state, or provenance moments, never as broad decorative color
- institutional credibility through precise taxonomy, measured captions, accessible contrast, and calm interaction states
- non-orientalist cultural specificity grounded in calligraphy criticism, archive practice, and contemporary ink abstraction

### Anti-Values

- bamboo, dragon, lantern, fan, or souvenir-calligraphy motifs used as shorthand for culture
- shallow black-red minimalism where a red accent is expected rather than semantically earned
- brush-script display fonts that mimic handwriting without typographic discipline
- busy dashboard density, equal card rows, or generic SaaS charts that erase the art-object context
- decorative texture that reduces legibility or makes scholarship feel like packaging

### Visual Character

- Warm off-white page backgrounds use layered radial and linear gradients plus low-opacity noise to simulate xuan-paper fibers without image assets.
- Large asymmetrical catalogue plates place one dominant artwork record beside narrow vertical metadata rails and expansive empty paper fields.
- Dry-brush dividers are CSS gradient strokes with irregular opacity stops, tapering widths, and blur-filtered edges rather than solid rules.
- Seal vermilion appears as tiny square stamps, status dots, and provenance ticks only at authorship or verification points.
- Typography pairs sober Chinese-supporting serif display with quiet sans text and mono accession labels, all tightly tracked and carefully led.

## Rules

### Composition

Use catalogue-spread asymmetry: one dominant record, one narrow taxonomy rail, one open paper field, and a few dense annotation clusters. Keep full-width moments rare, vary section weight, and let dry-brush rules define reading direction instead of boxy dashboards.

### Density

Overall density is low to medium: spacious paper fields dominate, but archive rows and provenance tables can become compact when adjacent to a large quiet void.

### Hierarchy

Display hierarchy comes from scale, empty field, and metadata precision: large serif title at 56-88px desktop, small uppercase mono accessions, 16px body annotations, and seal-red marks only for verified authorship or selected states.

### Signature Patterns

- A pressure rail uses layered linear-gradients with variable thickness and opacity to mimic dry-to-wet brush force along a metadata column.
- Catalogue plates carry xuan-fiber texture through pseudo-elements combining repeating-linear-gradients and radial ink blooms clipped to the surface.
- Vermilion seal squares are semantic UI punctuation: selected object, verified provenance, or authorship marker, never a decorative icon set.
- Object records use an asymmetric void grid where the artwork silhouette sits off-center and captions align to narrow scholarly rails.
- Hover and focus states deepen ink halos and sharpen accession labels, suggesting absorption and attention without adding new colors.

## Layout

### Breakpoints

mobile <= 640px, tablet 641px-1024px, desktop >= 1025px; rails collapse above content on mobile and plates stack with preserved void margins.

### Density

Low-density primary screens with dense scholarly clusters only in rails, footnotes, accession lists, and filter taxonomies.

### Grid

Desktop uses a 14-column grid: 2 columns for collection rail, 7 for dominant plate/void, 3 for annotations, and 2 held empty; gutters 24px, max-width 1520px.

### Responsive

At tablet widths the annotation rail moves below the hero plate; at mobile widths seal marks remain small, brush rails become horizontal, and long headings wrap at 1.1 line-height.

### Whitespace

Whitespace is a material field, not leftover space: 4-12px inside metadata clusters, 48-128px between interpretive sections, and deliberately blank plate areas around artwork records.

## Guidance

### Do

- Use warm paper whites and layered ink blacks, with texture subtle enough that long scholarly text remains readable.
- Reserve vermilion for provenance, authorship, active selection, or critical annotation markers only.
- Build layouts around one dominant catalogue object and at least one large quiet negative field.
- Represent brush pressure through CSS stroke structure, irregular rules, opacity, and edge behavior rather than literal calligraphy decoration.
- Pair object titles, dynasty/artist metadata, medium, accession numbers, and interpretive notes like a credible museum archive.
- Keep corners mostly square, borders hairline-light, and shadows soft enough to read as paper lift rather than app chrome.
- Use mono labels for accession and taxonomy codes to distinguish scholarship from interpretive prose.
- Maintain accessible contrast by placing all body copy on calmer paper surfaces, not over heavy ink blooms.

### Don't

- Do not use bamboo, dragons, lanterns, fans, chopstick imagery, or generic red-circle Asian branding.
- Do not use brush-script fonts or fake handwritten titles to imply calligraphy.
- Do not make red a broad brand color; repeated red buttons or red borders cheapen the seal logic.
- Do not fill the screen with equal cards or analytics widgets; this is an archive and catalogue system, not a dashboard.
- Do not use high-saturation neon accents, glossy gradients, or friendly rounded SaaS components.
- Do not let texture become grunge; xuan fibers should be almost tactile, not dirty.
- Do not center every element; disciplined off-center placement is part of the ink composition.
- Do not flatten all records into uniform list rows when a featured plate needs slow looking time.

### Accessibility

Body text uses high-contrast near-black on warm paper, focus states combine outline and seal mark, red is never the sole status signal, and texture opacity stays below legibility thresholds.

### Usage Context

Best for museum collection interfaces, contemporary ink exhibition microsites, scholarly catalogue tools, archival object records, and premium cultural institution product systems.

# Xuan Archive Ink Catalogue

## Overview

A scholarly gallery interface language for contemporary Chinese ink and calligraphic abstraction, translating brush pressure, xuan-paper absorption, seal discipline, and catalogue scholarship into a quiet production-ready product system. It treats ink as evidence of force and time rather than decoration: wide paper fields, dry-to-wet tonal layers, measured archive metadata, and a single vermilion provenance mark organize the experience without resorting to tourist calligraphy or generic East Asian motifs.

### Values

- material specificity: xuan-paper fibers, ink absorption, pressure variation, and dry brush edges become structural UI decisions
- scholarly restraint with enough expressive gesture to feel like contemporary art rather than a sterile database
- negative space as active composition, giving each object record room to breathe like an album leaf or catalogue plate
- seal vermilion used only for authorship, state, or provenance moments, never as broad decorative color
- institutional credibility through precise taxonomy, measured captions, accessible contrast, and calm interaction states
- non-orientalist cultural specificity grounded in calligraphy criticism, archive practice, and contemporary ink abstraction

### Anti-Values

- bamboo, dragon, lantern, fan, or souvenir-calligraphy motifs used as shorthand for culture
- shallow black-red minimalism where a red accent is expected rather than semantically earned
- brush-script display fonts that mimic handwriting without typographic discipline
- busy dashboard density, equal card rows, or generic SaaS charts that erase the art-object context
- decorative texture that reduces legibility or makes scholarship feel like packaging

### Visual Character

- Warm off-white page backgrounds use layered radial and linear gradients plus low-opacity noise to simulate xuan-paper fibers without image assets.
- Large asymmetrical catalogue plates place one dominant artwork record beside narrow vertical metadata rails and expansive empty paper fields.
- Dry-brush dividers are CSS gradient strokes with irregular opacity stops, tapering widths, and blur-filtered edges rather than solid rules.
- Seal vermilion appears as tiny square stamps, status dots, and provenance ticks only at authorship or verification points.
- Typography pairs sober Chinese-supporting serif display with quiet sans text and mono accession labels, all tightly tracked and carefully led.

## 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/xuan-archive-ink-catalogue/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 paper whites and layered ink blacks, with texture subtle enough that long scholarly text remains readable.
- Do Reserve vermilion for provenance, authorship, active selection, or critical annotation markers only.
- Do Build layouts around one dominant catalogue object and at least one large quiet negative field.
- Do Represent brush pressure through CSS stroke structure, irregular rules, opacity, and edge behavior rather than literal calligraphy decoration.
- Do Pair object titles, dynasty/artist metadata, medium, accession numbers, and interpretive notes like a credible museum archive.
- Do Keep corners mostly square, borders hairline-light, and shadows soft enough to read as paper lift rather than app chrome.
- Do Use mono labels for accession and taxonomy codes to distinguish scholarship from interpretive prose.

# Xuan Archive Ink Catalogue shadcn/ui Components

Artifact: `component-recipes-v1`
Author: `katagami-ui-projection`
Language ID: `xuan-archive-ink-catalogue`
Slug: `xuan-archive-ink-catalogue`

## Intent

A scholarly gallery interface language for contemporary Chinese ink and calligraphic abstraction, translating brush pressure, xuan-paper absorption, seal discipline, and catalogue scholarship into a quiet production-ready product system. It treats ink as evidence of force and time rather than decoration: wide paper fields, dry-to-wet tonal layers, measured archive metadata, and a single vermilion provenance mark organize the experience without resorting to tourist calligraphy or generic East Asian motifs.

## 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": "#A73524",
  "background": "#F4F0E6",
  "border": "#1D1A1614",
  "error": "#9F3A2F",
  "info": "#4E6670",
  "muted": "#7B7468",
  "primary": "#1D1A16",
  "secondary": "#6F675B",
  "success": "#596F55",
  "surface": "#FBF8EF",
  "text": "#171411",
  "warning": "#A77D3A"
}

Typography:

{
  "base_size": "16px",
  "body_font": "Noto Sans SC",
  "google_fonts_url": "https://fonts.googleapis.com/css2?family=Azeret+Mono:wght@400;500;600&family=Noto+Sans+SC:wght@400;500;600;700&family=Noto+Serif+SC:wght@500;600;700&display=swap",
  "heading_font": "Noto Serif SC",
  "letter_spacing": "-0.02em",
  "line_height": 1.56,
  "mono_font": "Azeret Mono",
  "scale_ratio": 1.26
}

## Visual character to preserve

- Warm off-white page backgrounds use layered radial and linear gradients plus low-opacity noise to simulate xuan-paper fibers without image assets.
- Large asymmetrical catalogue plates place one dominant artwork record beside narrow vertical metadata rails and expansive empty paper fields.
- Dry-brush dividers are CSS gradient strokes with irregular opacity stops, tapering widths, and blur-filtered edges rather than solid rules.
- Seal vermilion appears as tiny square stamps, status dots, and provenance ticks only at authorship or verification points.
- Typography pairs sober Chinese-supporting serif display with quiet sans text and mono accession labels, all tightly tracked and carefully led.

## ShadSync visual profile

{
  "family": "paper-collage",
  "material": "paper",
  "contour": "blob",
  "border": "solid",
  "underlay": true,
  "grain": true,
  "stickerBadges": true,
  "motion": "still",
  "density": "balanced",
  "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/xuan-archive-ink-catalogue/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 paper whites and layered ink blacks, with texture subtle enough that long scholarly text remains readable.; Reserve vermilion for provenance, authorship, active selection, or critical annotation markers only.; Build layouts around one dominant catalogue object and at least one large quiet negative field.; Represent brush pressure through CSS stroke structure, irregular rules, opacity, and edge behavior rather than literal calligraphy decoration.; Pair object titles, dynasty/artist metadata, medium, accession numbers, and interpretive notes like a credible museum archive.; Keep corners mostly square, borders hairline-light, and shadows soft enough to read as paper lift rather than app chrome.; Use mono labels for accession and taxonomy codes to distinguish scholarship from interpretive prose.; Maintain accessible contrast by placing all body copy on calmer paper surfaces, not over heavy ink blooms.
- Do not: Do not use bamboo, dragons, lanterns, fans, chopstick imagery, or generic red-circle Asian branding.; Do not use brush-script fonts or fake handwritten titles to imply calligraphy.; Do not make red a broad brand color; repeated red buttons or red borders cheapen the seal logic.; Do not fill the screen with equal cards or analytics widgets; this is an archive and catalogue system, not a dashboard.; Do not use high-saturation neon accents, glossy gradients, or friendly rounded SaaS components.; Do not let texture become grunge; xuan fibers should be almost tactile, not dirty.; Do not center every element; disciplined off-center placement is part of the ink composition.; Do not flatten all records into uniform list rows when a featured plate needs slow looking time.

## Layout notes

{
  "breakpoints": "mobile <= 640px, tablet 641px-1024px, desktop >= 1025px; rails collapse above content on mobile and plates stack with preserved void margins.",
  "density": "Low-density primary screens with dense scholarly clusters only in rails, footnotes, accession lists, and filter taxonomies.",
  "grid": "Desktop uses a 14-column grid: 2 columns for collection rail, 7 for dominant plate/void, 3 for annotations, and 2 held empty; gutters 24px, max-width 1520px.",
  "responsive": "At tablet widths the annotation rail moves below the hero plate; at mobile widths seal marks remain small, brush rails become horizontal, and long headings wrap at 1.1 line-height.",
  "whitespace": "Whitespace is a material field, not leftover space: 4-12px inside metadata clusters, 48-128px between interpretive sections, and deliberately blank plate areas around artwork records."
