rules
Build screens as archival streetscapes: one dominant facade panel, two supporting registers, and a marginal evidence rail, all aligned to a strict civic grid with intentional overlaps.
Medium-high editorial density with generous exterior margins, compact internal ledgers, and enough quiet stone background to make collage layers feel curated.
Serif headlines act as building inscriptions, uppercase sans labels act as signs, mono numbers identify records, and saturated accents are reserved for state, route, or citation.
layout
mobile <= 640px, tablet 641px-980px, desktop >= 981px; overlap reduces on mobile but cornice headers and sticker labels remain visible.
Designed for collection review, provenance work, editorial planning, and cultural dashboards where many artifacts need hierarchy without becoming a spreadsheet.
Desktop uses a 12-column max-width 1240px facade grid with 7/5 and 4/4/4 spans plus an evidence rail; tablet folds to 6 columns and mobile to a single annotated stack.
Outer whitespace is broad like a museum wall, while cards use tight 8-16px ledgers and 24-32px section gaps to keep archival density controlled.
guidance
- Use historic quotation as layout mechanics: cornices for headers, plaques for metadata, pilasters for grouped content, and route signs for navigation.
- Preserve strong contrast between poster-black text, cream surfaces, and saturated oxblood or teal state labels.
- Make every collage layer meaningful with real product copy, status, provenance, or selection state.
- Keep controls usable: clear focus outlines, readable labels, stable hit areas, and motion limited to small index-card lifts.
- Do not scatter random ornaments, columns, stickers, or Memphis shapes that are not tied to interface hierarchy.
- Do not replace the archival palette with neon vaporwave, pastel blobs, glass panels, or bland white SaaS neutrals.
- Do not make all cards equal rectangles; the language needs one dominant facade and varied registers.
- Do not let rotated labels, halftone texture, or double borders interfere with text legibility or form completion.

# Facade Index Collage ## Philosophy Facade Index Collage treats software as an annotated city block: classical facades, museum placards, civic signs, archival stickers, and modern controls are layered into a legible critical interface rather than flattened into neutral SaaS. ### Values - Historic quotation used as structure: lintels, plaques, cornices, and pilasters become hierarchy, not decoration. - Pluralist collage with accountable layers, where every overlapping label, tab, and citation points to a product state or provenance detail. - High-contrast archival calm punctuated by oxblood, teal, brass, and dusty blue to support scanning without losing postmodern wit. - Useful irony: exaggerated facade gestures frame serious editorial, collection, and review workflows. ### Anti-Values - Generic white dashboard cards, glassmorphism, smooth startup gradients, or minimalism that erases the language of citation. - Theme-park historicism where columns and ornaments become fake illustration instead of functional layout devices. - Memphis clutter, random stickers, or novelty geometry that harms reading order and control affordance. ### Visual Character - Use a 12-column civic facade grid with offset card spans, shallow stepped cornice bars, and plaque-like section headers built from CSS borders. - Layer cream paper panels over stone backgrounds with poster-black keylines, small brass shadow offsets, and controlled z-index sticker tabs. - Combine serif display headings, grotesk body text, and mono accession numbers with uppercase tracking for signage and archival labels. - Create quotation frames through pseudo-element pilaster strips, oxblood corner stamps, teal route markers, and dusty-blue marginal notes. ## Tokens ### Borders - **Accent Width**: 6px - **Character**: poster-black civic signage outlines with brass and oxblood quotation accents - **Default Width**: 2px - **Style**: solid with occasional double-rule header lines ### Colors | Name | Value | |------|-------| | accent | `#B88A3A` | | background | `#D8D0C2` | | border | `#1E1A16` | | error | `#9E2D2D` | | info | `#557F9B` | | muted | `#6F675D` | | primary | `#0F2F33` | | secondary | `#7B2636` | | success | `#2E6D57` | | surface | `#F4EBDD` | | text | `#171411` | | warning | `#C7922A` | ### Motion - **Duration**: 180ms - **Easing**: cubic-bezier(.2,.8,.2,1) - **Philosophy**: controls lift by one brass offset and tabs slide like index cards;

# Facade Index Collage
## Overview
Facade Index Collage treats software as an annotated city block: classical facades, museum placards, civic signs, archival stickers, and modern controls are layered into a legible critical interface rather than flattened into neutral SaaS.
### Values
- Historic quotation used as structure: lintels, plaques, cornices, and pilasters become hierarchy, not decoration.
- Pluralist collage with accountable layers, where every overlapping label, tab, and citation points to a product state or provenance detail.
- High-contrast archival calm punctuated by oxblood, teal, brass, and dusty blue to support scanning without losing postmodern wit.
- Useful irony: exaggerated facade gestures frame serious editorial, collection, and review workflows.
### Anti-Values
- Generic white dashboard cards, glassmorphism, smooth startup gradients, or minimalism that erases the language of citation.
- Theme-park historicism where columns and ornaments become fake illustration instead of functional layout devices.
- Memphis clutter, random stickers, or novelty geometry that harms reading order and control affordance.
### Visual Character
- Use a 12-column civic facade grid with offset card spans, shallow stepped cornice bars, and plaque-like section headers built from CSS borders.
- Layer cream paper panels over stone backgrounds with poster-black keylines, small brass shadow offsets, and controlled z-index sticker tabs.
- Combine serif display headings, grotesk body text, and mono accession numbers with uppercase tracking for signage and archival labels.
- Create quotation frames through pseudo-element pilaster strips, oxblood corner stamps, teal route markers, and dusty-blue marginal notes.
## Colors
Use the YAML color tokens as the normative palette. The prose below names the roles agents should preserve when generating UI.
| Token | Value |
|-------|-------|
| accent | `#B88A3A` |
| background | `#D8D0C2` |
| border | `#1E1A16` |
| error | `#9E2D2D` |
| info | `#557F9B` |
| muted | `#6F675D` |
| primary | `#0F2F33` |
| secondary | `#7B2636` |
| success | `#2E6D57` |
| surface | `#F4EBDD` |
| text | `#171411` |
| warning | `#C7922A` |

### Grid
Desktop uses a 12-column max-width 1240px facade grid with 7/5 and 4/4/4 spans plus an evidence rail; tablet folds to 6 columns and mobile to a single annotated stack.
### Whitespace
Outer whitespace is broad like a museum wall, while cards use tight 8-16px ledgers and 24-32px section gaps to keep archival density controlled.
## Elevation & Depth
### Shadows
- **Lg**: 14px 14px 0 rgba(30,26,22,0.18)
- **Md**: 7px 7px 0 rgba(15,47,51,0.28)
- **Sm**: 3px 3px 0 #B88A3A

### Rounded
- **Full**: `9999px`
- **Lg**: `14px`
- **Md**: `6px`
- **None**: `0px`
- **Sm**: `2px`
### Surfaces
- **Bg Pattern**: subtle limestone grid, tiny accession ticks, and faint masonry joints made from layered linear gradients
- **Card Style**: plaque cards with square tops, small radii only on controls, heavy poster-black outlines, and cornice header bands
- **Treatment**: warm stone field with halftone speckle, cream archival panels, black ink rules, and brass offset shadows
### Borders
- **Accent Width**: 6px
- **Character**: poster-black civic signage outlines with brass and oxblood quotation accents
- **Default Width**: 2px
- **Style**: solid with occasional double-rule header lines
## Components
### Composition
Build screens as archival streetscapes: one dominant facade panel, two supporting registers, and a marginal evidence rail, all aligned to a strict civic grid with intentional overlaps.
### Density
Medium-high editorial density with generous exterior margins, compact internal ledgers, and enough quiet stone background to make collage layers feel curated.
### Hierarchy
Serif headlines act as building inscriptions, uppercase sans labels act as signs, mono numbers identify records, and saturated accents are reserved for state, route, or citation.
### Signature Patterns
- Cornice headers: double-rule black title bars with small brass offset shadows and serif inscriptions anchored above each major module.
- Citation stickers: rotated but readable tabs in oxblood, teal, and dusty blue that overlap card edges while containing live status labels.
- Facade frames: pseudo-element side pilasters and bottom plinth rules that turn cards, dialogs, and sheets into quoted architectural fragments.
- Accession ledgers: mono micro-labels, dotted rule rows, and plaque badges that expose provenance, version, and review state.
## 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-019e6677-62e6-7a42-b6ca-5c1357346c51/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 historic quotation as layout mechanics: cornices for headers, plaques for metadata, pilasters for grouped content, and route signs for navigation.
- Do Preserve strong contrast between poster-black text, cream surfaces, and saturated oxblood or teal state labels.
- Do Make every collage layer meaningful with real product copy, status, provenance, or selection state.
- Do Keep controls usable: clear focus outlines, readable labels, stable hit areas, and motion limited to small index-card lifts.
- Don't Do not scatter random ornaments, columns, stickers, or Memphis shapes that are not tied to interface hierarchy.
- Don't Do not replace the archival palette with neon vaporwave, pastel blobs, glass panels, or bland white SaaS neutrals.
- Don't Do not make all cards equal rectangles; the language needs one dominant facade and varied registers.
- Don't Do not let rotated labels, halftone texture, or double borders interfere with text legibility or form completion.
### Accessibility
Core text and controls meet WCAG AA contrast; rotated stickers remain short and redundant with nearby text; keyboard focus uses high-contrast teal outlines plus brass offset.
### Usage Context
Best for cultural archives, planning tools, research collections, editorial provenance systems, civic review workflows, and products that need scholarly seriousness with postmodern quotation.

# Facade Index Collage shadcn/ui Components
Artifact: `component-recipes-v1`
Author: `katagami-ui-projection`
Language ID: `en-019e6677-62e6-7a42-b6ca-5c1357346c51`
Slug: `facade-index-collage`
## Intent
Facade Index Collage treats software as an annotated city block: classical facades, museum placards, civic signs, archival stickers, and modern controls are layered into a legible critical interface rather than flattened into neutral SaaS.
## 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

"letter_spacing": "-0.01em",
"line_height": 1.5,
"mono_font": "IBM Plex Mono",
"scale_ratio": 1.24
}
## Visual character to preserve
- Use a 12-column civic facade grid with offset card spans, shallow stepped cornice bars, and plaque-like section headers built from CSS borders.
- Layer cream paper panels over stone backgrounds with poster-black keylines, small brass shadow offsets, and controlled z-index sticker tabs.
- Combine serif display headings, grotesk body text, and mono accession numbers with uppercase tracking for signage and archival labels.
- Create quotation frames through pseudo-element pilaster strips, oxblood corner stamps, teal route markers, and dusty-blue marginal notes.
## ShadSync visual profile

"motion": "lift-rotate",

}
## 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/facade-index-collage/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 historic quotation as layout mechanics: cornices for headers, plaques for metadata, pilasters for grouped content, and route signs for navigation.; Preserve strong contrast between poster-black text, cream surfaces, and saturated oxblood or teal state labels.; Make every collage layer meaningful with real product copy, status, provenance, or selection state.; Keep controls usable: clear focus outlines, readable labels, stable hit areas, and motion limited to small index-card lifts.
- Do not: Do not scatter random ornaments, columns, stickers, or Memphis shapes that are not tied to interface hierarchy.; Do not replace the archival palette with neon vaporwave, pastel blobs, glass panels, or bland white SaaS neutrals.; Do not make all cards equal rectangles; the language needs one dominant facade and varied registers.; Do not let rotated labels, halftone texture, or double borders interfere with text legibility or form completion.
## 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
{
"breakpoints": "mobile <= 640px, tablet 641px-980px, desktop >= 981px; overlap reduces on mobile but cornice headers and sticker labels remain visible.",
"density": "Designed for collection review, provenance work, editorial planning, and cultural dashboards where many artifacts need hierarchy without becoming a spreadsheet.",
"grid": "Desktop uses a 12-column max-width 1240px facade grid with 7/5 and 4/4/4 spans plus an evidence rail; tablet folds to 6 columns and mobile to a single annotated stack.",
"whitespace": "Outer whitespace is broad like a museum wall, while cards use tight 8-16px ledgers and 24-32px section gaps to keep archival density controlled."
