rules
composition
Build screens as asymmetric archival spreads: one dominant j-card/cassette schematic, a narrow CLI evidence rail, taped note fragments, and a large quiet paper field. Avoid equal columns; use one grid break where a diagram crosses fold lines or escapes into the margin. Preserve strict alignment of labels, ticks, and coordinate marks even when paper panels are offset.
density
Alternate dense forensic clusters of 4-8px gaps with broad 64-96px archive whitespace so the system feels studied, not busy. Diagrams may be packed with callouts while surrounding vellum remains calm.
hierarchy
Display hierarchy comes from width, case, and instrument scale: oversized condensed headings act like anime title cards, serif body notes carry recovered testimony, and monospace labels provide tiny operational truth. Accent color marks active scan points only; primary reading order is black ink, brown tape mass, then luminous cursor.
signature patterns
J-card fold grid: panels use vertical spine strips, fold-rule lines, and rectangular inset windows that mimic cassette packaging rather than standard cards.Tape-path schematic: CSS circles, bars, and hairline connectors create visible cassette reel geometry that remains recognizable without the color palette.CLI annotation rail: a narrow right or bottom rail contains prompt symbols, coordinate labels, checksum codes, and blinking cursors aligned to scan ticks.Registration bracket overlay: corners, dashed crosshair lines, and numbered calibration dots sit above content as a precise machine-vision layer.Taped-in lab note fragments: small rotated but digitally aligned paper slips use mono hand numbers and serif observations to add archive warmth without clutter.
layout
breakpoints
Mobile under 640px stacks the schematic, notes, and CLI rail; tablet 640-1024px uses a 6-column spread; desktop above 1024px restores the asymmetric 12-column j-card layout.
density

Medium-high informational density inside diagrams and CLI rails, offset by large untouched paper margins to meet an archive-notebook rhythm.

grid
Desktop uses a 12-column max-width 1320px archival spread with 24px gutters; dominant schematic spans 7 columns, evidence rail spans 3, and margins carry callouts.
responsive

Preserve square cassette geometry with aspect-ratio, convert rails to horizontal command strips on mobile, and keep labels legible at 15px body scale.

whitespace

Whitespace should feel like blank vellum around evidence: 8px within callout clusters, 24-32px inside panels, and 64-96px between major archival sections.

guidance
do
  • Use squared paper panels, fold lines, cassette windows, and tape-path diagrams as the main structural vocabulary.
  • Keep luminous cyan or phosphor green accents sparse and functional: cursors, scan ticks, registration points, or active coordinates only.
  • Mix condensed industrial title typography with serif archive notes and tiny monospace catalog labels for three distinct voices.
  • Let black linework and brown oxide masses carry recognition before adding any accent color.
  • Create at least one asymmetric grid break where a diagram, rail, or taped note crosses the expected fold.
  • Use near-invisible borders and matte paper shadows instead of glossy cards or heavy elevation.
  • Name fictional products as archive tools, memory labs, cassette indexes, or signal-recovery instruments.
avoid
  • Do not use neon purple cyberpunk gradients, glassmorphism, chrome reflections, or club lighting.
  • Do not arrange three equal metric cards or generic dashboard widgets; every screen needs a scene and a dominant artifact.
  • Do not add distressed grunge textures so heavy that labels, diagrams, or registration overlays become illegible.
  • Do not use friendly rounded SaaS components, pill-heavy navigation, or stock app shells.
  • Do not let anime references become character illustration; keep references in title composition, terminal overlays, and precise linework.
  • Do not spend accent color on decoration when black, cream, and tape brown can solve hierarchy.
  • Do not use banned default AI fonts or default browser form styling.

# Cassette Cyberpunk Lab Notes

## Philosophy

Cassette Cyberpunk Lab Notes is a warm forensic interface language for recovering analog memory through machine vision: cream vellum, oxidized tape browns, hand-numbered cassette diagrams, and terminal annotations placed with exact registration discipline.

### Values

- Analog evidence first: every surface should feel like paper, tape stock, photocopy toner, or a handled archive sleeve rather than polished glass.
- Precision without coldness: digital overlays, scan brackets, calibration ticks, and CLI labels must align surgically while preserving quiet material warmth.
- Diagrammatic storytelling: interfaces explain themselves through numbered callouts, tape-path schematics, cassette-window frames, and small catalog codes.
- Restrained luminance: phosphor green or desaturated cyan appears only as an active cursor, scan point, or registration mark.
- Manga-line economy: black-and-white contour work carries form; color only stains the substrate or highlights machine-readable events.
- Existential archive calm: compositions should feel like recovered notes from a lab that treats memories as fragile evidence.

### Anti-Values

- Generic neon cyberpunk gradients, glossy panels, purple-blue nightclub palettes, or synthetic glow used as decoration.
- Rounded SaaS cards, equal dashboard widgets, soft pastel friendliness, and anonymous analytics layouts.
- Fake grunge overload: torn edges, splatter, heavy noise, and distressed type that obscures the forensic registration system.
- Anime pastiche without structure: decorative characters or fan-art references replacing cassette mechanics and interface logic.

### Visual Character

- Use cream paper backgrounds with subtle linear-rule and dot-grid pseudo-elements, overlaid by absolute-positioned scan brackets and calibration ticks in accent color.
- Construct primary panels as j-card fold rectangles: squared corners, thin photocopy-black borders, vertical spine labels, and taped-in inset windows offset from the grid.
- Render cassette mechanics with CSS-only line diagrams: two circular reel wells, horizontal tape paths, oxide-brown bars, and numbered mono callout tags.
- Combine sparse manga linework with digital registration overlays by pairing 1px black contour strokes with dashed cyan or phosphor guide lines placed above the paper layer.
- Set typography in condensed industrial headings, readable serif notes, and tiny monospace CLI annotations with negative tracking and hand-numbered catalog codes.

## Rules

### Composition

Build screens as asymmetric archival spreads: one dominant j-card/cassette schematic, a narrow CLI evidence rail, taped note fragments, and a large quiet paper field. Avoid equal columns; use one grid break where a diagram crosses fold lines or escapes into the margin. Preserve strict alignment of labels, ticks, and coordinate marks even when paper panels are offset.

### Density

Alternate dense forensic clusters of 4-8px gaps with broad 64-96px archive whitespace so the system feels studied, not busy. Diagrams may be packed with callouts while surrounding vellum remains calm.

### Hierarchy

Display hierarchy comes from width, case, and instrument scale: oversized condensed headings act like anime title cards, serif body notes carry recovered testimony, and monospace labels provide tiny operational truth. Accent color marks active scan points only; primary reading order is black ink, brown tape mass, then luminous cursor.

### Signature Patterns

- J-card fold grid: panels use vertical spine strips, fold-rule lines, and rectangular inset windows that mimic cassette packaging rather than standard cards.
- Tape-path schematic: CSS circles, bars, and hairline connectors create visible cassette reel geometry that remains recognizable without the color palette.
- CLI annotation rail: a narrow right or bottom rail contains prompt symbols, coordinate labels, checksum codes, and blinking cursors aligned to scan ticks.
- Registration bracket overlay: corners, dashed crosshair lines, and numbered calibration dots sit above content as a precise machine-vision layer.
- Taped-in lab note fragments: small rotated but digitally aligned paper slips use mono hand numbers and serif observations to add archive warmth without clutter.

## Layout

### Breakpoints

Mobile under 640px stacks the schematic, notes, and CLI rail; tablet 640-1024px uses a 6-column spread; desktop above 1024px restores the asymmetric 12-column j-card layout.

### Density

Medium-high informational density inside diagrams and CLI rails, offset by large untouched paper margins to meet an archive-notebook rhythm.

### Grid

Desktop uses a 12-column max-width 1320px archival spread with 24px gutters; dominant schematic spans 7 columns, evidence rail spans 3, and margins carry callouts.

### Responsive

Preserve square cassette geometry with aspect-ratio, convert rails to horizontal command strips on mobile, and keep labels legible at 15px body scale.

### Whitespace

Whitespace should feel like blank vellum around evidence: 8px within callout clusters, 24-32px inside panels, and 64-96px between major archival sections.

## Guidance

### Do

- Use squared paper panels, fold lines, cassette windows, and tape-path diagrams as the main structural vocabulary.
- Keep luminous cyan or phosphor green accents sparse and functional: cursors, scan ticks, registration points, or active coordinates only.
- Mix condensed industrial title typography with serif archive notes and tiny monospace catalog labels for three distinct voices.
- Let black linework and brown oxide masses carry recognition before adding any accent color.
- Create at least one asymmetric grid break where a diagram, rail, or taped note crosses the expected fold.
- Use near-invisible borders and matte paper shadows instead of glossy cards or heavy elevation.
- Name fictional products as archive tools, memory labs, cassette indexes, or signal-recovery instruments.

### Don't

- Do not use neon purple cyberpunk gradients, glassmorphism, chrome reflections, or club lighting.
- Do not arrange three equal metric cards or generic dashboard widgets; every screen needs a scene and a dominant artifact.
- Do not add distressed grunge textures so heavy that labels, diagrams, or registration overlays become illegible.
- Do not use friendly rounded SaaS components, pill-heavy navigation, or stock app shells.
- Do not let anime references become character illustration; keep references in title composition, terminal overlays, and precise linework.
- Do not spend accent color on decoration when black, cream, and tape brown can solve hierarchy.
- Do not use banned default AI fonts or default browser form styling.

### Accessibility

Maintain strong body contrast between #241711 and #F4E7C8, keep mono labels at 12px minimum, do not rely on cyan alone for status, and provide text labels for diagram states.

### Usage Context

Best for fictional archive tools, analog media recovery systems, terminal-assisted cataloging, cassette restoration labs, retro-future title screens, and narrative interfaces about memory preservation.

# Cassette Cyberpunk Lab Notes

## Overview

Cassette Cyberpunk Lab Notes is a warm forensic interface language for recovering analog memory through machine vision: cream vellum, oxidized tape browns, hand-numbered cassette diagrams, and terminal annotations placed with exact registration discipline.

### Values

- Analog evidence first: every surface should feel like paper, tape stock, photocopy toner, or a handled archive sleeve rather than polished glass.
- Precision without coldness: digital overlays, scan brackets, calibration ticks, and CLI labels must align surgically while preserving quiet material warmth.
- Diagrammatic storytelling: interfaces explain themselves through numbered callouts, tape-path schematics, cassette-window frames, and small catalog codes.
- Restrained luminance: phosphor green or desaturated cyan appears only as an active cursor, scan point, or registration mark.
- Manga-line economy: black-and-white contour work carries form; color only stains the substrate or highlights machine-readable events.
- Existential archive calm: compositions should feel like recovered notes from a lab that treats memories as fragile evidence.

### Anti-Values

- Generic neon cyberpunk gradients, glossy panels, purple-blue nightclub palettes, or synthetic glow used as decoration.
- Rounded SaaS cards, equal dashboard widgets, soft pastel friendliness, and anonymous analytics layouts.
- Fake grunge overload: torn edges, splatter, heavy noise, and distressed type that obscures the forensic registration system.
- Anime pastiche without structure: decorative characters or fan-art references replacing cassette mechanics and interface logic.

### Visual Character

- Use cream paper backgrounds with subtle linear-rule and dot-grid pseudo-elements, overlaid by absolute-positioned scan brackets and calibration ticks in accent color.
- Construct primary panels as j-card fold rectangles: squared corners, thin photocopy-black borders, vertical spine labels, and taped-in inset windows offset from the grid.
- Render cassette mechanics with CSS-only line diagrams: two circular reel wells, horizontal tape paths, oxide-brown bars, and numbered mono callout tags.
- Combine sparse manga linework with digital registration overlays by pairing 1px black contour strokes with dashed cyan or phosphor guide lines placed above the paper layer.
- Set typography in condensed industrial headings, readable serif notes, and tiny monospace CLI annotations with negative tracking and hand-numbered catalog codes.

Avoid equal columns; use one grid break where a diagram crosses fold lines or escapes into the margin. Preserve strict alignment of labels, ticks, and coordinate marks even when paper panels are offset.

Display hierarchy comes from width, case, and instrument scale: oversized condensed headings act like anime title cards, serif body notes carry recovered testimony, and monospace labels provide tiny operational truth. Accent color marks active scan points only; primary reading order is black ink, brown tape mass, then luminous cursor.

### Signature Patterns

- J-card fold grid: panels use vertical spine strips, fold-rule lines, and rectangular inset windows that mimic cassette packaging rather than standard cards.
- Tape-path schematic: CSS circles, bars, and hairline connectors create visible cassette reel geometry that remains recognizable without the color palette.
- CLI annotation rail: a narrow right or bottom rail contains prompt symbols, coordinate labels, checksum codes, and blinking cursors aligned to scan ticks.
- Registration bracket overlay: corners, dashed crosshair lines, and numbered calibration dots sit above content as a precise machine-vision layer.
- Taped-in lab note fragments: small rotated but digitally aligned paper slips use mono hand numbers and serif observations to add archive warmth without clutter.

## 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/cassette-cyberpunk-lab-notes/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.

# Cassette Cyberpunk Lab Notes shadcn/ui Components

Artifact: `component-recipes-v1`
Author: `katagami-ui-projection`
Language ID: `cassette-cyberpunk-lab-notes`
Slug: `cassette-cyberpunk-lab-notes`

## Intent

Cassette Cyberpunk Lab Notes is a warm forensic interface language for recovering analog memory through machine vision: cream vellum, oxidized tape browns, hand-numbered cassette diagrams, and terminal annotations placed with exact registration discipline.

## 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": "#8AAEA7",
  "background": "#F4E7C8",
  "border": "#2A1711",
  "error": "#9A4E2F",
  "info": "#4B7278",
  "muted": "#6E5848",
  "primary": "#5A3826",
  "secondary": "#2A1711",
  "success": "#4F6F58",
  "surface": "#D8C39A",
  "text": "#241711",
  "warning": "#7B4B22"
}

Typography:

{
  "base_size": "16px",
  "body_font": "IBM Plex Serif",
  "display_letter_spacing": "-0.04em",
  "google_fonts_url": "https://fonts.googleapis.com/css2?family=Teko:wght@400;500;600&family=IBM+Plex+Serif:wght@400;500;600&family=Share+Tech+Mono&display=swap",
  "heading_font": "Teko",
  "letter_spacing": "-0.02em",
  "line_height": 1.55,
  "mono_font": "Share Tech Mono",
  "scale_ratio": 1.22
}

## Visual character to preserve

- Use cream paper backgrounds with subtle linear-rule and dot-grid pseudo-elements, overlaid by absolute-positioned scan brackets and calibration ticks in accent color.
- Construct primary panels as j-card fold rectangles: squared corners, thin photocopy-black borders, vertical spine labels, and taped-in inset windows offset from the grid.
- Render cassette mechanics with CSS-only line diagrams: two circular reel wells, horizontal tape paths, oxide-brown bars, and numbered mono callout tags.
- Combine sparse manga linework with digital registration overlays by pairing 1px black contour strokes with dashed cyan or phosphor guide lines placed above the paper layer.
- Set typography in condensed industrial headings, readable serif notes, and tiny monospace CLI annotations with negative tracking and hand-numbered catalog codes.

## ShadSync visual profile

{
  "family": "paper-collage",
  "material": "paper",
  "contour": "default",
  "border": "dashed",
  "underlay": true,
  "grain": true,

  "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/cassette-cyberpunk-lab-notes/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 squared paper panels, fold lines, cassette windows, and tape-path diagrams as the main structural vocabulary.; Keep luminous cyan or phosphor green accents sparse and functional: cursors, scan ticks, registration points, or active coordinates only.; Mix condensed industrial title typography with serif archive notes and tiny monospace catalog labels for three distinct voices.; Let black linework and brown oxide masses carry recognition before adding any accent color.; Create at least one asymmetric grid break where a diagram, rail, or taped note crosses the expected fold.; Use near-invisible borders and matte paper shadows instead of glossy cards or heavy elevation.; Name fictional products as archive tools, memory labs, cassette indexes, or signal-recovery instruments.
- Do not: Do not use neon purple cyberpunk gradients, glassmorphism, chrome reflections, or club lighting.; Do not arrange three equal metric cards or generic dashboard widgets; every screen needs a scene and a dominant artifact.; Do not add distressed grunge textures so heavy that labels, diagrams, or registration overlays become illegible.; Do not use friendly rounded SaaS components, pill-heavy navigation, or stock app shells.; Do not let anime references become character illustration; keep references in title composition, terminal overlays, and precise linework.; Do not spend accent color on decoration when black, cream, and tape brown can solve hierarchy.; Do not use banned default AI fonts or default browser form styling.

## Layout notes

{
  "breakpoints": "Mobile under 640px stacks the schematic, notes, and CLI rail; tablet 640-1024px uses a 6-column spread; desktop above 1024px restores the asymmetric 12-column j-card layout.",
  "density": "Medium-high informational density inside diagrams and CLI rails, offset by large untouched paper margins to meet an archive-notebook rhythm.",
  "grid": "Desktop uses a 12-column max-width 1320px archival spread with 24px gutters; dominant schematic spans 7 columns, evidence rail spans 3, and margins carry callouts.",
  "responsive": "Preserve square cassette geometry with aspect-ratio, convert rails to horizontal command strips on mobile, and keep labels legible at 15px body scale.",
  "whitespace": "Whitespace should feel like blank vellum around evidence: 8px within callout clusters, 24-32px inside panels, and 64-96px between major archival sections."
