# Marginal Paper Rhythm shadcn/ui Components

Artifact: `component-recipes-v1`
Author: `katagami-ui-projection`
Language ID: `en-019edc15-ba9c-76b1-b08c-52daf29da43b`
Slug: `marginal-paper-rhythm`

## Intent

Marginal Paper Rhythm is a quiet product UI language for dense reading, review, and annotation workflows. It treats the central text column as the primary path, then layers metadata, sidenotes, and contextual controls into a stable margin system that feels paper-like without becoming decorative.

## 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": "#5B638F",
  "background": "#F4F0E7",
  "border": "#D8D0C1",
  "error": "#A45A4F",
  "info": "#566A8E",
  "muted": "#817A6E",
  "primary": "#35495F",
  "secondary": "#6F7B61",
  "success": "#5E7A59",
  "surface": "#FBF8F0",
  "text": "#2D2A24",
  "warning": "#A8793F"
}

Typography:

{
  "base_size": "16px",
  "body_font": "IBM Plex Sans",
  "google_fonts_url": "https://fonts.googleapis.com/css2?family=IBM+Plex+Mono:wght@400;500&family=IBM+Plex+Sans:wght@400;450;500;600&family=Noto+Sans+JP:wght@400;500;600&display=swap",
  "heading_font": "Noto Sans JP",
  "letter_spacing": "-0.01em",
  "line_height": 1.62,
  "mono_font": "IBM Plex Mono",
  "scale_ratio": 1.18
}

## Visual character to preserve

- A three-column reading grid uses a wide central measure with narrow muted marginal rails for metadata, timestamps, and annotation anchors.
- Surfaces use warm paper backgrounds with faint vertical grain and one-pixel rule lines instead of raised cards or glossy shadows.
- Typography is role-based: calm sans body text, small mono metadata, and restrained weight shifts rather than decorative headings.
- Annotation accents appear as desaturated indigo and moss side rules, bracket marks, and small numbered seals positioned outside the reading flow.

## ShadSync visual profile

{
  "family": "paper-collage",
  "material": "paper",
  "contour": "default",
  "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/marginal-paper-rhythm/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 body text between 62 and 78 characters per line and use line-height above 1.55 for reading-heavy views.; Place labels, timestamps, provenance, and counts in predictable marginal positions with muted color and mono type.; Use indigo for active annotations, moss for supportive context, and sepia rules for neutral structure.; Represent nested context with indentation, rules, and lower contrast before adding new cards.
- Do not: Do not use expressive hero headings, decorative kanji motifs, bright gradients, or large rounded SaaS cards.; Do not make every metadata item a pill badge; reserve seals and labels for scannable anchors only.; Do not interrupt the main reading path with modals or floating context unless the user explicitly enters edit mode.; Do not compress line-height below readability thresholds just to show more rows.

## 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 below 640px collapses rails into stacked context drawers; tablet 640-1024px keeps the left rail compact and moves sidenotes below active sections; desktop above 1100px uses full marginal rails.",
  "grid": "Desktop grid: 176px left index rail, minmax(560px, 760px) reading column, 248px right annotation rail with 24px gutters.",
  "whitespace": "Whitespace is rhythmic rather than large: 8px base tokens, 24px paragraph groups, 32px section breaks, and stable gutters that prevent metadata from touching body copy."
