# Shoji Loom

## Philosophy

Shoji Loom is a restrained language for text-heavy AI context products: luminous warm paper planes, graphite typography, thread-like accents, and layered translucent panels that let context feel woven rather than dashboarded.

### Values

- quiet reading focus
- layered context without clutter
- warm precision
- progressive disclosure
- usable restraint

### Anti-Values

- neon glassmorphism
- analytics-first dashboard density
- decorative Japanese pastiche
- heavy cards and shadows

### Visual Character

- Use warm off-white page and panel layers with subtle linear-gradient paper grain and no pure white canvases.
- Build hierarchy from 1px translucent graphite seams and fine inset rules instead of boxed card borders everywhere.
- Place content on an 8px rhythm with a centered reading pane, a slim metadata rail, and secondary translucent paper slips.
- Represent active context as thin indigo or saffron threads, margin dots, underlines, and small chips under five percent of the viewport.
- Use soft rectangular radii and warm low-spread shadows only where panels physically overlap like sheets of washi.

### Values

- quiet reading focus
- layered context without clutter
- warm precision
- progressive disclosure

### Anti-Values

- neon glassmorphism
- analytics-first dashboard density

- Build hierarchy from 1px translucent graphite seams and fine inset rules instead of boxed card borders everywhere.
- Place content on an 8px rhythm with a centered reading pane, a slim metadata rail, and secondary translucent paper slips.
- Represent active context as thin indigo or saffron threads, margin dots, underlines, and small chips under five percent of the viewport.
- Use soft rectangular radii and warm low-spread shadows only where panels physically overlap like sheets of washi.

## 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-019ee039-4f65-7020-bea2-2d69cc76103d/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 graphite text on warm paper with human line heights for long reading sessions.
- Do Make every accent a thread, knot, underline, or small selection state with limited coverage.
- Do Let secondary context overlap as translucent paper slips with visible seams and depth.
- Don't Do not use blue neon blur, glossy glass, or frosted nightclub effects.
- Don't Do not turn the first screen into a dense analytics dashboard.
- Don't Do not paste ornamental Japanese motifs; express the reference through grid, paper, light, and restraint.

# Shoji Loom shadcn/ui Components

Artifact: `component-recipes-v1`
Author: `katagami-ui-projection`
Language ID: `en-019ee039-4f65-7020-bea2-2d69cc76103d`
Slug: `shoji-loom`

## Intent

Shoji Loom is a restrained language for text-heavy AI context products: luminous warm paper planes, graphite typography, thread-like accents, and layered translucent panels that let context feel woven rather than dashboarded.

## 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": "#C58A2A",
  "background": "#FFFCF5",
  "border": "#D8CDBB",
  "error": "#A24C3D",
  "info": "#42647A",
  "muted": "#6F6A61",
  "primary": "#2F4A60",
  "secondary": "#EFE7DA",
  "success": "#537A5A",
  "surface": "#F7F2E8",
  "text": "#262626",
  "warning": "#B57924"
}

Typography:

{
  "base_size": "16px",
  "body_font": "IBM Plex Sans",
  "google_fonts_url": "https://fonts.googleapis.com/css2?family=Fraunces:opsz,wght@9..144,500;9..144,600&family=IBM+Plex+Mono:wght@400;500&family=IBM+Plex+Sans:wght@400;450;500;600&display=swap",
  "heading_font": "Fraunces",
  "letter_spacing": "-0.01em",
  "line_height": 1.62,
  "mono_font": "IBM Plex Mono",
  "scale_ratio": 1.22
}

## Visual character to preserve

- Use warm off-white page and panel layers with subtle linear-gradient paper grain and no pure white canvases.
- Build hierarchy from 1px translucent graphite seams and fine inset rules instead of boxed card borders everywhere.
- Place content on an 8px rhythm with a centered reading pane, a slim metadata rail, and secondary translucent paper slips.
- Represent active context as thin indigo or saffron threads, margin dots, underlines, and small chips under five percent of the viewport.
- Use soft rectangular radii and warm low-spread shadows only where panels physically overlap like sheets of washi.

## ShadSync visual profile

{
  "family": "paper-collage",
  "material": "paper",
  "contour": "default",
  "border": "solid",
  "underlay": false,
  "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/shoji-loom/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 graphite text on warm paper with human line heights for long reading sessions.; Make every accent a thread, knot, underline, or small selection state with limited coverage.; Let secondary context overlap as translucent paper slips with visible seams and depth.
- Do not: Do not use blue neon blur, glossy glass, or frosted nightclub effects.; Do not turn the first screen into a dense analytics dashboard.; Do not paste ornamental Japanese motifs; express the reference through grid, paper, light, and restraint.

## Copy-paste component example

This generated starter proves the import shape. Production Katagami agents should replace it with a language-specific product composition.
