# Magnetic School Computer Club shadcn/ui Components

Artifact: `component-recipes-v1`
Author: `katagami-ui-projection`
Language ID: `magnetic-school-computer-club`
Slug: `magnetic-school-computer-club`

## Intent

Magnetic School Computer Club is a warm, low-stakes interface language for tools that feel maintained by an after-school computing club: cream ABS plastic windows, floppy label fields, manga worksheet gutters, BASIC-era prompts, blue ballpoint corrections, and quiet cybernetic questions written as marginal notes rather than alarms.

## 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": "#1F66A7",
  "background": "#F6EEDC",
  "border": "#20201C",
  "error": "#9B3D37",
  "info": "#6DAEB8",
  "muted": "#6F6A5D",
  "primary": "#20201C",
  "secondary": "#E7DCC5",
  "success": "#4F6B4A",
  "surface": "#FFF8E8",
  "text": "#20201C",
  "warning": "#A86D2A"
}

Typography:

{
  "base_size": "16px",
  "body_font": "BIZ UDPGothic",
  "google_fonts_url": "https://fonts.googleapis.com/css2?family=BIZ+UDPGothic:wght@400;700&family=Kiwi+Maru:wght@400;500&family=M+PLUS+1+Code:wght@400;500;700&display=swap",
  "heading_font": "Kiwi Maru",
  "letter_spacing": "-0.02em",
  "line_height": 1.55,
  "mono_font": "M PLUS 1 Code",
  "scale_ratio": 1.22
}

## Visual character to preserve

- Build primary containers as cream CRT bezel windows with 2px ink outlines, inset off-white highlights, square corner notches, and thick bottom label lips.
- Organize information in manga worksheet panels: uneven gutters, ruled paper baselines, screentone dot fills, blue correction circles, and taped marginal notes.
- Use floppy-disk label strips as navigation and metadata fields, with faded cyan label blocks, binder-tab red flags, and monospaced filename captions.
- Render terminal output as marginalia: tiny BASIC prompts, compile jokes, caret cursors, and graphite status readouts tucked into panel edges.
- Make annotations visibly hand-applied through blue ballpoint underlines, circled variables, diagonal arrows, and offset sticky-note rotations in CSS.

## ShadSync visual profile

{
  "family": "paper-collage",
  "material": "paper",
  "contour": "pebble",
  "border": "dashed",
  "underlay": true,
  "grain": true,
  "stickerBadges": false,
  "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/magnetic-school-computer-club/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: Lead with cream ABS plastic and aged paper; let near-black ink and blue ballpoint provide the recognizable structure.; Use uneven manga gutters, taped labels, ruled fields, and screentone as layout devices rather than decorative stickers.; Write interface copy as club artifacts: disk names, BASIC prompts, after-school times, parts checkout, and gentle compile jokes.; Keep red and cyan scarce: red only for binder tabs or urgent club notes, cyan only for floppy-label material.; Make the product scene specific, such as a lab checkout and BASIC practice console for a fictional school computer club.; Use square or notched corners on primary panels, reserving 16px/24px radii only for paper notes and correction circles.; Preserve visible focus states with blue pen outlines, dashed ink boxes, and text labels paired with all color states.
- Do not: Do not use green matrix rain, neon purple/cyan glow, or dark hacker dashboard backgrounds.; Do not arrange three equal cards in a row; one workbench or worksheet area must clearly dominate.; Do not introduce full anime characters, mascot fan art, or glossy robot illustrations.; Do not use generic analytics charts, CRM metrics, SaaS rounded cards, or icon-heavy product grids.; Do not over-distress textures; paper aging should be subtle enough for a polished product interface.; Do not choose chrome sci-fi display fonts or default system UI typography; keep the manuscript/mono contrast.; Do not rely on color alone for status; pair red tabs, blue circles, and green success with clear copy.

## 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": ">=1120px keeps the asymmetric workbench; 760px-1119px becomes a two-column worksheet with notes below; <760px stacks panels and preserves horizontal floppy labels as scroll-free rows.",
  "density": "Medium-high information density is localized: labels and prompts are compact, while the overall composition breathes with large clubroom-paper margins.",
  "grid": "Desktop uses a 12-column max-width 1320px worksheet grid with 24px gutters; the CRT workbench spans seven columns while notes and floppy trays occupy asymmetric side columns.",
