# Margin Thread Reading Room shadcn/ui Components

Artifact: `component-recipes-v1`
Author: `katagami-ui-projection`
Language ID: `en-019edc15-fdfb-78e0-91bb-dcbb2db84d4a`
Slug: `margin-thread-reading-room`

## Intent

A quiet editorial synthesis studio for AYA where long prose remains central while evidence, decisions, backlinks, and analytical fragments gather as restrained marginalia rather than competing dashboard panels.

## 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": "#B87832",
  "background": "#F3EBDD",
  "border": "#D6C7B0",
  "error": "#9B3D2E",
  "info": "#546F82",
  "muted": "#7F7468",
  "primary": "#33281E",
  "secondary": "#7B5E3B",
  "success": "#55724B",
  "surface": "#FFF9ED",
  "text": "#241E19",
  "warning": "#B87832"
}

Typography:

{
  "base_size": "16px",
  "body_font": "Literata",
  "google_fonts_url": "https://fonts.googleapis.com/css2?family=Newsreader:opsz,wght@6..72,400;6..72,520;6..72,650&family=Literata:opsz,wght@7..72,400;7..72,500;7..72,600&family=IBM+Plex+Mono:wght@400;500;600&display=swap",
  "heading_font": "Newsreader",
  "letter_spacing": "-0.012em",
  "line_height": 1.62,
  "mono_font": "IBM Plex Mono",
  "scale_ratio": 1.24
}

## Visual character to preserve

- A centered minmax prose column is flanked by narrow margin rails using CSS grid columns of 260px minmax(520px,720px) 300px, collapsing rails below tablet widths.
- Warm paper backgrounds use subtle repeating-linear-gradient fiber and low-contrast ink borders so every module feels printed into the page rather than elevated like a card.
- Annotations are anchored by hairline leader rules and small numbered chips positioned along the prose baseline, with compact excerpt drawers revealed as inline marginal blocks.
- Command and decision surfaces appear as compressed horizontal inserts with mono labels, square ink outlines, and one muted ochre accent bar instead of colorful buttons.
- Context maps use thin connector lines, backlink pills, and nested thread indentation to show relationships while preserving a single calm reading rhythm.

## ShadSync visual profile

{
  "family": "paper-collage",
  "material": "paper",
  "contour": "pebble",
  "border": "solid",
  "underlay": false,
  "grain": true,
  "stickerBadges": true,
  "motion": "still",
  "density": "dense",
  "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/margin-thread-reading-room/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: Keep prose centered and readable before adding analytical modules.; Use hairline rules, source numbers, and backlinks to make provenance visible.; Prefer flat paper surfaces, square geometry, and restrained ochre accents.; Collapse secondary context into marginal summaries before showing full excerpts.
- Do not: Do not turn the workspace into a KPI dashboard or card grid.; Do not mix pillowy radii with square editorial components.; Do not use bright semantic colors as the main identity.; Do not obscure reading flow with oversized graphs or chat bubbles.

## Copy-paste component example

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