Art Deco Revival translates interwar luxury graphics into a contemporary product interface: ceremonial hierarchy, architectural symmetry, lacquer-dark surfaces, metallic linework, and theatrical framing. It treats interface moments like lobby entrances and ticket counters—every section is announced, bordered, and aligned with intentional grandeur rather than casual utility.

Favor centered and axial compositions with strong header-to-content procession. Major regions should feel like rooms in a grand interior: marquee header, stat salon, reservation ledger, itinerary sidebar. Use nested frames to define zones instead of loose cards floating in space.
hierarchy
Make headlines ceremonial and uppercase, subtitles elegant and literary, and data labels restrained but aligned. Important actions should appear as framed plaques or gilded capsules. Numeric information should stack vertically and center-align before resolving into detailed tables.
density
Medium density with generous top and bottom breathing room, but internally precise and gridded. Decorative detail lives in rules, dividers, and framing rather than excessive copy or dense iconography.
signature patterns
every primary panel uses a double border created with an outer border plus inset box-shadow rulesection headers carry a fanburst divider built from repeating linear-gradient rayscards, dialogs, and highlighted callouts use chamfered corners via clip-path polygonsstat blocks center their values and labels in vertically stacked columns separated by metallic hairlinesbuttons and badges use stepped inline accents with small geometric corner caps rendered by pseudo-elements
layout
grid
Desktop uses a 12-column ceremonial grid with a wide central content lane and balanced side regions. The hero spans full width, metrics occupy four columns each, the ledger/table spans eight columns, and the itinerary or form rail spans four. At tablet sizes this condenses to 8 columns, then 4, then a single-column stacked procession on phone.
breakpoints
At 1024px reduce ornamental margins and move the side rail beneath the ledger. At 768px collapse metric panels into a two-column salon and stack header actions. At 480px all framed modules become single-column, buttons go full width, tabs scroll, and tables remain usable inside horizontal overflow wrappers.
whitespace
Use dramatic outer margins and tall sectional spacing to preserve grandeur. Inside components keep measured rhythm based on 8px units, with extra padding reserved for marquee areas and modal interiors.
guidance
do
  • use symmetry or near-symmetry for major page regions
  • frame important content with double rules and inset accents
  • pair decorative display typography with refined readable serif body text
  • treat alerts, modals, and forms like formal announcements rather than casual overlays
  • use gold sparingly but decisively on structure, hierarchy, and focal actions
avoid
  • do not introduce soft rounded cards or pillowy neumorphism
  • do not rely on bright multicolor accents that dilute the gold-on-lacquer palette
  • do not left-align every element by default when a centered axis would create drama
  • do not remove decorative dividers; the linework is structural, not optional
  • do not use generic sans-serif display typography for headlines

# Art Deco Revival

## Philosophy

Art Deco Revival translates interwar luxury graphics into a contemporary product interface: ceremonial hierarchy, architectural symmetry, lacquer-dark surfaces, metallic linework, and theatrical framing. It treats interface moments like lobby entrances and ticket counters—every section is announced, bordered, and aligned with intentional grandeur rather than casual utility.

### Values

- ornament with discipline
- ceremonial hierarchy and strong axial alignment
- luxury conveyed through contrast and finish rather than clutter
- graphic geometry that feels architectural and collectible
- dramatic framing around important information

### Anti-Values

- soft casual minimalism
- blob-like organic shapes
- playful rounded consumer app tropes
- invisible structure or borderless layouts
- flat utilitarian typography without drama

### Visual Character

- all major panels sit inside double-line metallic frames with a narrow inset gap
- section titles use uppercase high-contrast serif typography with wide letterspacing and a geometric fanburst divider beneath
- cards and modals feature chamfered top corners that create a faceted marquee silhouette
- dark lacquer backgrounds are overlaid with repeating gold pinstripes and stepped sunburst geometry
- data emphasis appears in vertically stacked number blocks with thin separator rules and centered composition

## Overview

Art Deco Revival translates interwar luxury graphics into a contemporary product interface: ceremonial hierarchy, architectural symmetry, lacquer-dark surfaces, metallic linework, and theatrical framing. It treats interface moments like lobby entrances and ticket counters—every section is announced, bordered, and aligned with intentional grandeur rather than casual utility.

### Values

- ornament with discipline
- ceremonial hierarchy and strong axial alignment
- luxury conveyed through contrast and finish rather than clutter
- graphic geometry that feels architectural and collectible
- dramatic framing around important information

### Anti-Values

- soft casual minimalism
- blob-like organic shapes
- playful rounded consumer app tropes
- invisible structure or borderless layouts
- flat utilitarian typography without drama

### Visual Character

- all major panels sit inside double-line metallic frames with a narrow inset gap
- section titles use uppercase high-contrast serif typography with wide letterspacing and a geometric fanburst divider beneath
- cards and modals feature chamfered top corners that create a faceted marquee silhouette
- dark lacquer backgrounds are overlaid with repeating gold pinstripes and stepped sunburst geometry
- data emphasis appears in vertically stacked number blocks with thin separator rules and centered composition

The hero spans full width, metrics occupy four columns each, the ledger/table spans eight columns, and the itinerary or form rail spans four. At tablet sizes this condenses to 8 columns, then 4, then a single-column stacked procession on phone.

### Breakpoints

At 1024px reduce ornamental margins and move the side rail beneath the ledger. At 768px collapse metric panels into a two-column salon and stack header actions. At 480px all framed modules become single-column, buttons go full width, tabs scroll, and tables remain usable inside horizontal overflow wrappers.

### Whitespace

Use dramatic outer margins and tall sectional spacing to preserve grandeur. Inside components keep measured rhythm based on 8px units, with extra padding reserved for marquee areas and modal interiors.

## Components

### Composition

Favor centered and axial compositions with strong header-to-content procession. Major regions should feel like rooms in a grand interior: marquee header, stat salon, reservation ledger, itinerary sidebar. Use nested frames to define zones instead of loose cards floating in space.

### Hierarchy

Make headlines ceremonial and uppercase, subtitles elegant and literary, and data labels restrained but aligned. Important actions should appear as framed plaques or gilded capsules. Numeric information should stack vertically and center-align before resolving into detailed tables.

### Density

Medium density with generous top and bottom breathing room, but internally precise and gridded. Decorative detail lives in rules, dividers, and framing rather than excessive copy or dense iconography.

### Signature Patterns

- every primary panel uses a double border created with an outer border plus inset box-shadow rule
- section headers carry a fanburst divider built from repeating linear-gradient rays
- cards, dialogs, and highlighted callouts use chamfered corners via clip-path polygons
- stat blocks center their values and labels in vertically stacked columns separated by metallic hairlines
- buttons and badges use stepped inline accents with small geometric corner caps rendered by pseudo-elements

## 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-019d9bb7-7e5a-7d20-a1db-a31cdf862161/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 symmetry or near-symmetry for major page regions
- Do frame important content with double rules and inset accents
- Do pair decorative display typography with refined readable serif body text
- Do treat alerts, modals, and forms like formal announcements rather than casual overlays
- Do use gold sparingly but decisively on structure, hierarchy, and focal actions
- Don't do not introduce soft rounded cards or pillowy neumorphism
- Don't do not rely on bright multicolor accents that dilute the gold-on-lacquer palette
- Don't do not left-align every element by default when a centered axis would create drama
- Don't do not remove decorative dividers; the linework is structural, not optional
- Don't do not use generic sans-serif display typography for headlines

# Art Deco Revival shadcn/ui Components

Artifact: `component-recipes-v1`
Author: `katagami-ui-projection`
Language ID: `en-019d9bb7-7e5a-7d20-a1db-a31cdf862161`
Slug: `art-deco-revival`

## Intent

Art Deco Revival translates interwar luxury graphics into a contemporary product interface: ceremonial hierarchy, architectural symmetry, lacquer-dark surfaces, metallic linework, and theatrical framing. It treats interface moments like lobby entrances and ticket counters—every section is announced, bordered, and aligned with intentional grandeur rather than casual utility.

## 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": "#1B1A1F",
  "secondary": "#332B2B",
  "accent": "#D4AF37",
  "background": "#0F0D12",
  "surface": "#17141C",
  "text": "#F4E9D8",
  "muted": "#B79F77",
  "border": "#8F6B2E",
  "error": "#C4544C",
  "success": "#4E8B63",
  "warning": "#C6922A",
  "info": "#5F7FA7"
}

Typography:

{
  "heading_font": "Cinzel Decorative",
  "body_font": "Cormorant Garamond",
  "mono_font": "IBM Plex Mono",
  "base_size": "18px",
  "scale_ratio": "1.25",
  "line_height": "1.5",
  "letter_spacing": "0.04em",
  "google_fonts_url": "https://fonts.googleapis.com/css2?family=Cinzel+Decorative:wght@400;700&family=Cormorant+Garamond:wght@400;500;600;700&family=IBM+Plex+Mono:wght@400;500&display=swap"
}

## Visual character to preserve

- all major panels sit inside double-line metallic frames with a narrow inset gap
- section titles use uppercase high-contrast serif typography with wide letterspacing and a geometric fanburst divider beneath
- cards and modals feature chamfered top corners that create a faceted marquee silhouette
- dark lacquer backgrounds are overlaid with repeating gold pinstripes and stepped sunburst geometry
- data emphasis appears in vertically stacked number blocks with thin separator rules and centered composition

## ShadSync visual profile

{
  "family": "editorial",
  "material": "flat",
  "contour": "default",
  "border": "solid",
  "underlay": false,
  "grain": false,
  "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/art-deco-revival/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 symmetry or near-symmetry for major page regions; frame important content with double rules and inset accents; pair decorative display typography with refined readable serif body text; treat alerts, modals, and forms like formal announcements rather than casual overlays; use gold sparingly but decisively on structure, hierarchy, and focal actions
- Do not: do not introduce soft rounded cards or pillowy neumorphism; do not rely on bright multicolor accents that dilute the gold-on-lacquer palette; do not left-align every element by default when a centered axis would create drama; do not remove decorative dividers; the linework is structural, not optional; do not use generic sans-serif display typography for headlines

## 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

{
  "grid": "Desktop uses a 12-column ceremonial grid with a wide central content lane and balanced side regions. The hero spans full width, metrics occupy four columns each, the ledger/table spans eight columns, and the itinerary or form rail spans four. At tablet sizes this condenses to 8 columns, then 4, then a single-column stacked procession on phone.",
  "breakpoints": "At 1024px reduce ornamental margins and move the side rail beneath the ledger. At 768px collapse metric panels into a two-column salon and stack header actions. At 480px all framed modules become single-column, buttons go full width, tabs scroll, and tables remain usable inside horizontal overflow wrappers.",
  "whitespace": "Use dramatic outer margins and tall sectional spacing to preserve grandeur. Inside components keep measured rhythm based on 8px units, with extra padding reserved for marquee areas and modal interiors."
