rules
Compose screens as reading rooms, not dashboards: one primary text stream, one woven context rail, and compact data surfaces nested as evidence rather than hero metrics.
High information density is allowed when line-height, gutters, and grouping rules preserve a calm scan path across long text and tabular evidence.
Use type weight, rule placement, paragraph measure, and sparse accent stitches to establish order; reserve large titles for page identity and keep labels small but high contrast.
layout
mobile 375px stacks rail controls above content; tablet 768px uses two columns with context below summary; desktop 1200px+ enables full reading room layout.
Desktop uses a 12-column content grid with a 72px left navigation rail, a 7-column reading span, and a 4-column context loom; panels may offset by 8-16px to interlace.
Whitespace is narrow but deliberate: 16px between text groups, 24px between modules, and longer 48px pauses only where a user changes task mode.
guidance
- Use real editorial product copy: decisions, source notes, entity mentions, confidence language, and revision history.
- Keep body text at 15-16px with generous line height and high ink contrast on warm off-white surfaces.
- Make craft references structural through thread rules, stencil breaks, repeat systems, and asymmetry rather than imagery.
- Use indigo or persimmon sparingly for active state, focus, one count, or one alert family per screen.
- Test dense screens at mobile widths so the reading column remains first and secondary context becomes collapsible or stacked.
- Do not create a metric-tile dashboard as the primary scene or make charts the hero of the language.
- Do not use decorative Japanese icons, paper textures that reduce contrast, brush fonts, or ornamental pattern walls.
- Do not rely on low-contrast gray text, pill overload, generic rounded cards, or colorful badge taxonomies.
- Do not fill buttons or headers with indigo unless the action is singular and primary.
- Do not center long-form product text or break reading measure beyond approximately 72 characters.

# Threadline Reading Loom ## Philosophy Threadline Reading Loom is a light, text-first SaaS language for AYA: many strands of context are woven into calm reading surfaces through hairline rules, staggered modules, and one disciplined accent. It references katagami and Japanese weaving as systems of negative space, repeat, and interruption rather than as decorative motifs. ### Values - Calm comprehension before display spectacle: long text, notes, decisions, and state changes stay readable at dense enterprise scale. - Craft as structure: thread lines, stencil voids, and modular repeats become alignment, grouping, and progressive disclosure. - Restrained hierarchy: importance is shown by position, rhythm, line weight, and small accent marks rather than heavy cards or loud color. - Asymmetric order: the interface feels composed by a thoughtful editor, with small offsets that prevent dashboard monotony. ### Anti-Values - No faux-Japanese clichés, brush calligraphy, red sun symbols, origami icons, or ornamental patterns pasted behind content. - No glossy dashboard chrome, saturated metric tiles, heavy shadows, or rounded SaaS default cards. - No low-contrast gray paragraphs or decorative density that harms scanning and accessibility. ### Visual Character - Use a warm off-white body ground with translucent paper surfaces separated by 1px gray thread rules and almost no drop shadow. - Build modules on a 12-column grid with selective 8px column offsets so text panels interlace rather than align as equal dashboard cards. - Apply repeating-linear-gradient thread backgrounds at 12px and 32px intervals only inside margins, rails, and quiet header bands. - Use one restrained indigo accent as 2px vertical stitches, small square bullets, focus rings, and sparse status marks, never as large fills. - Create katagami-like stencil apertures with clipped corner notches, inset rule frames, and negative-space labels embedded in borders. ## Tokens ### Borders - **Accent Width**: 2px - **Character**: fine gray thread rules with indigo stitch accents and occasional inset double-lines - **Default Width**: 1px - **Style**: solid ### Colors | Name | Value | |------|-------| | accent | `#34558B` | | background | `#F7F2E8` | | border | `#D8D2C7` | | error | `#9B3D32` | | info | `#34558B` | | muted | `#77746E` | | primary | `#26384F` | | secondary | `#6E6357` | | success | `#426B4D` | | surface | `#FFFDF7` | | text | `#1F2326` | | warning | `#9A6A26` | ### Motion - **Duration**: 160ms - **Easing**: cubic-bezier(0.2, 0, 0.1, 1) - **Philosophy**: quiet state confirmation: focus stitches sharpen, rows tint lightly, no bouncing or ornamental motion ### Radii - **Full**: 9999px - **Lg**: 8px - **Md**: 4px - **None**: 0 - **Sm**: 2px ### Shadows - **Lg**: 0 18px 42px rgba(38,56,79,0.10) - **Md**: 0 10px 24px rgba(38,56,79,0.07) - **Sm**: 0 1px 0 rgba(31,35,38,0.05) ### Spacing - **Base**: 8px - **Scale**: [4,8,12,16,24,32,48,64] ### Surfaces - **Bg Pattern**: two-layer repeating-linear-gradient using transparent gray thread lines at 12px and 32px intervals - **Card Style**: flat ivory panels with 1px thread border, inset accent stitch, and clipped/notched metadata corners - **Treatment**: warm paper fields with faint woven thread gradients in rails and headers ### Typography - **Base Size**: 16px - **Body Font**: IBM Plex Sans JP - **Google Fonts Url**: https://fonts.googleapis.com/css2?family=IBM+Plex+Sans+JP:wght@400;500;600&family=IBM+Plex+Mono:wght@400;500&family=Literata:opsz,wght@7..72,500;7..72,600&display=swap - **Heading Font**: Literata - **Letter Spacing**: -0.012em - **Line Height**: 1.58 - **Mono Font**: IBM Plex Mono - **Scale Ratio**: 1.18 ## Rules ### Composition Compose screens as reading rooms, not dashboards: one primary text stream, one woven context rail, and compact data surfaces nested as evidence rather than hero metrics. ### Density High information density is allowed when line-height, gutters, and grouping rules preserve a calm scan path across long text and tabular evidence. ### Hierarchy Use type weight, rule placement, paragraph measure, and sparse accent stitches to establish order; reserve large titles for page identity and keep labels small but high contrast. ### Signature Patterns - Thread rails: vertical or horizontal 1px rule clusters generated with repeating-linear-gradient and used to connect related notes across modules. - Stitched emphasis: a 2px indigo border segment or square marker identifies the current item, selected tab, focus state, or latest decision without filling the component. - Stencil labels: section labels sit inside small negative-space breaks in borders, creating a katagami aperture effect while keeping the content surface plain. - Interlaced offsets: secondary panels shift by one spacing unit or one grid column so context strands weave around the main reading column instead of forming equal cards. - Quiet evidence strips: table rows and status logs use alternating hairlines, mono timestamps, and tiny accent ticks to show system activity without dashboard framing. ## Layout ### Breakpoints mobile 375px stacks rail controls above content;

# Threadline Reading Loom
## Overview
Threadline Reading Loom is a light, text-first SaaS language for AYA: many strands of context are woven into calm reading surfaces through hairline rules, staggered modules, and one disciplined accent. It references katagami and Japanese weaving as systems of negative space, repeat, and interruption rather than as decorative motifs.
### Values
- Calm comprehension before display spectacle: long text, notes, decisions, and state changes stay readable at dense enterprise scale.
- Craft as structure: thread lines, stencil voids, and modular repeats become alignment, grouping, and progressive disclosure.
- Restrained hierarchy: importance is shown by position, rhythm, line weight, and small accent marks rather than heavy cards or loud color.
- Asymmetric order: the interface feels composed by a thoughtful editor, with small offsets that prevent dashboard monotony.
### Anti-Values
- No faux-Japanese clichés, brush calligraphy, red sun symbols, origami icons, or ornamental patterns pasted behind content.
- No glossy dashboard chrome, saturated metric tiles, heavy shadows, or rounded SaaS default cards.
- No low-contrast gray paragraphs or decorative density that harms scanning and accessibility.
### Visual Character
- Use a warm off-white body ground with translucent paper surfaces separated by 1px gray thread rules and almost no drop shadow.
- Build modules on a 12-column grid with selective 8px column offsets so text panels interlace rather than align as equal dashboard cards.
- Apply repeating-linear-gradient thread backgrounds at 12px and 32px intervals only inside margins, rails, and quiet header bands.
- Use one restrained indigo accent as 2px vertical stitches, small square bullets, focus rings, and sparse status marks, never as large fills.
- Create katagami-like stencil apertures with clipped corner notches, inset rule frames, and negative-space labels embedded in borders.
## 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 | `#34558B` |
| background | `#F7F2E8` |
| border | `#D8D2C7` |
| error | `#9B3D32` |
| info | `#34558B` |
| muted | `#77746E` |
| primary | `#26384F` |
| secondary | `#6E6357` |
| success | `#426B4D` |
| surface | `#FFFDF7` |
| text | `#1F2326` |
| warning | `#9A6A26` |

### Whitespace
Whitespace is narrow but deliberate: 16px between text groups, 24px between modules, and longer 48px pauses only where a user changes task mode.
## Elevation & Depth

## Shapes
### Rounded
- **Full**: `9999px`
- **Lg**: `8px`
- **Md**: `4px`
- **None**: `0px`
- **Sm**: `2px`
### Surfaces

- **Card Style**: flat ivory panels with 1px thread border, inset accent stitch, and clipped/notched metadata corners
- **Treatment**: warm paper fields with faint woven thread gradients in rails and headers
### Borders
- **Accent Width**: 2px
- **Character**: fine gray thread rules with indigo stitch accents and occasional inset double-lines
- **Default Width**: 1px
- **Style**: solid
## Components
### Composition
Compose screens as reading rooms, not dashboards: one primary text stream, one woven context rail, and compact data surfaces nested as evidence rather than hero metrics.
### Density
High information density is allowed when line-height, gutters, and grouping rules preserve a calm scan path across long text and tabular evidence.
### Hierarchy
Use type weight, rule placement, paragraph measure, and sparse accent stitches to establish order; reserve large titles for page identity and keep labels small but high contrast.
### Signature Patterns
- Thread rails: vertical or horizontal 1px rule clusters generated with repeating-linear-gradient and used to connect related notes across modules.
- Stitched emphasis: a 2px indigo border segment or square marker identifies the current item, selected tab, focus state, or latest decision without filling the component.
- Stencil labels: section labels sit inside small negative-space breaks in borders, creating a katagami aperture effect while keeping the content surface plain.
- Interlaced offsets: secondary panels shift by one spacing unit or one grid column so context strands weave around the main reading column instead of forming equal cards.
- Quiet evidence strips: table rows and status logs use alternating hairlines, mono timestamps, and tiny accent ticks to show system activity without dashboard framing.
## 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-019edab2-cc74-74d3-94a9-6eb31a4fc571/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 real editorial product copy: decisions, source notes, entity mentions, confidence language, and revision history.
- Do Keep body text at 15-16px with generous line height and high ink contrast on warm off-white surfaces.
- Do Make craft references structural through thread rules, stencil breaks, repeat systems, and asymmetry rather than imagery.
- Do Use indigo or persimmon sparingly for active state, focus, one count, or one alert family per screen.
- Do Test dense screens at mobile widths so the reading column remains first and secondary context becomes collapsible or stacked.
- Don't Do not create a metric-tile dashboard as the primary scene or make charts the hero of the language.
- Don't Do not use decorative Japanese icons, paper textures that reduce contrast, brush fonts, or ornamental pattern walls.
- Don't Do not rely on low-contrast gray text, pill overload, generic rounded cards, or colorful badge taxonomies.
- Don't Do not fill buttons or headers with indigo unless the action is singular and primary.
- Don't Do not center long-form product text or break reading measure beyond approximately 72 characters.
### Accessibility
Maintain WCAG AA contrast, visible indigo focus rings, semantic button and form states, and non-color indicators such as stitches, labels, and row rules.

# Threadline Reading Loom shadcn/ui Components
Artifact: `component-recipes-v1`
Author: `katagami-ui-projection`
Language ID: `en-019edab2-cc74-74d3-94a9-6eb31a4fc571`
Slug: `threadline-reading-loom`
## Intent
Threadline Reading Loom is a light, text-first SaaS language for AYA: many strands of context are woven into calm reading surfaces through hairline rules, staggered modules, and one disciplined accent. It references katagami and Japanese weaving as systems of negative space, repeat, and interruption rather than as decorative 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`.

}
## Visual character to preserve
- Use a warm off-white body ground with translucent paper surfaces separated by 1px gray thread rules and almost no drop shadow.
- Build modules on a 12-column grid with selective 8px column offsets so text panels interlace rather than align as equal dashboard cards.
- Apply repeating-linear-gradient thread backgrounds at 12px and 32px intervals only inside margins, rails, and quiet header bands.
- Use one restrained indigo accent as 2px vertical stitches, small square bullets, focus rings, and sparse status marks, never as large fills.
- Create katagami-like stencil apertures with clipped corner notches, inset rule frames, and negative-space labels embedded in borders.

}
## 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/threadline-reading-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 real editorial product copy: decisions, source notes, entity mentions, confidence language, and revision history.; Keep body text at 15-16px with generous line height and high ink contrast on warm off-white surfaces.; Make craft references structural through thread rules, stencil breaks, repeat systems, and asymmetry rather than imagery.; Use indigo or persimmon sparingly for active state, focus, one count, or one alert family per screen.; Test dense screens at mobile widths so the reading column remains first and secondary context becomes collapsible or stacked.
- Do not: Do not create a metric-tile dashboard as the primary scene or make charts the hero of the language.; Do not use decorative Japanese icons, paper textures that reduce contrast, brush fonts, or ornamental pattern walls.; Do not rely on low-contrast gray text, pill overload, generic rounded cards, or colorful badge taxonomies.; Do not fill buttons or headers with indigo unless the action is singular and primary.; Do not center long-form product text or break reading measure beyond approximately 72 characters.
## 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 375px stacks rail controls above content; tablet 768px uses two columns with context below summary; desktop 1200px+ enables full reading room layout.",
"grid": "Desktop uses a 12-column content grid with a 72px left navigation rail, a 7-column reading span, and a 4-column context loom; panels may offset by 8-16px to interlace.",
"whitespace": "Whitespace is narrow but deliberate: 16px between text groups, 24px between modules, and longer 48px pauses only where a user changes task mode."
