System-console layout: open masthead nav across the header, a command rail, a large operations workspace, and a telemetry column aligned to an 8px grid.
Primary hierarchy comes from phosphor brightness, uppercase prompt labels, amber-ticked panels, and tabular rows; the largest type is still monospaced and technical.
Dense by default with compact rows and narrow gutters, while preserving enough line height for readable operational dashboards on small screens.
CRT scanline overlay; terminal syntax-mark prefixes; amber corner ticks via pseudo-elements; block-cursor focus/selection; fixed-width command-output rows with color-coded status tokens.
Desktop uses a 220px command rail, flexible central workspace, and 300px telemetry column; internal panels follow 8px increments.
Compact and mechanical: 8px row gaps, 16-24px panel padding; large empty areas only inside output panes to imply screen depth.

lumiphor
Subjects are rendered as the phosphor signal itself — radar sweeps, waveform terrain, oscilloscope traces — in luminous emerald monochrome with scanlines, dot-matrix dithering, CRT bloom, and scarce amber/cyan flecks. Render the signal, not the screen.

# Phosphor ## Philosophy Phosphor turns green-screen terminal discipline into a modern operations console: dense monospace rows on black glass, amber-ticked instrument panels, and a block cursor that marks where the system is listening — luminous, legible, never nostalgic. ### Values - Operational clarity before ornament - Authentic terminal rhythm from monospaced rows and command prompts - High-contrast status communication with restrained accent colour - Enterprise hierarchy anchored by grid discipline and repeatable components ### Anti-Values - Rounded lifestyle-app softness that breaks the machine-console character - Rainbow cyberpunk excess or decorative glitch that obscures content - Skeuomorphic monitor bezels, fake hardware chrome, or novelty terminal jokes ### Visual Character - Every panel draws zero-radius 1px phosphor borders with amber corner ticks for a calibrated instrument edge. - The interface sits on a deep black-green ground with layered scanlines and a radial phosphor glow behind the working area. - Headers, labels, and controls use uppercase IBM Plex Mono with terminal-syntax prefixes ($, >, ::, [01]). - Hierarchy is built from terminal rows, tabular metric cells, and fixed-width prompt blocks, not soft cards. - Interactive elements expose a block cursor: focused inputs and active tabs show a rectangular phosphor caret or a solid left bar. ## Tokens ### Colors | Name | Value | |------|-------| | bg | `#040907` | | surface | `#0A1411` | | recess | `#0F1D18` | | text | `#D9FFE9` | | muted | `#7FB89C` | | primary | `#36F08A` | | secondary | `#0F1D18` | | accent | `#36F08A` | | on_accent | `#04150C` | | amber | `#FFB454` | | cyan | `#5FE1FF` | | success | `#36F08A` | | warning | `#FFB454` | | error | `#FF5D78` | | info | `#5FE1FF` | | border | `#1C5B42` | ### Typography - **Base Size**: 16px - **Body Font**: IBM Plex Mono - **Heading Font**: IBM Plex Mono - **Mono Font**: IBM Plex Mono - **Heading Weight**: 600 - **Heading Transform**: uppercase - **Letter Spacing**: 0.01em - **Line Height**: 1.55 - **Scale Ratio**: 1.2 - **Google Fonts Url**: https://fonts.googleapis.com/css2?family=IBM+Plex+Mono:wght@400;500;600;700&display=swap ### Radii - **None**: 0 - **Sm**: 0 - **Md**: 0 - **Lg**: 0 - **Full**: 9999px ### Shadows - **Sm**: 0 0 10px rgba(54,240,138,0.16) - **Md**: 0 0 24px rgba(54,240,138,0.18), inset 0 0 18px rgba(54,240,138,0.04) - **Lg**: 0 0 60px rgba(54,240,138,0.22), inset 0 0 30px rgba(95,225,255,0.04) - **Focus**: 0 0 12px rgba(54,240,138,0.28) ### Spacing - **Base**: 8px - **Scale**: [4,8,12,16,24,32,48,64] ### Surfaces - **Bg Pattern**: scanlines - **Card Style**: Flat black-glass panels with subtle CRT scanlines, inner phosphor glow, square edges, amber corner ticks, and command-line header strips. - **Treatment**: scanline ### Borders - **Default Width**: 1px - **Accent Width**: 2px - **Style**: solid - **Character**: Thin phosphor grid lines define every region;

let amber and cyan stay scarce, operational accents. - Prefix labels and actions with terminal marks rendered as text; right-align numbers in phosphor. - Bracket panels with amber corner ticks; mark focus and selection with the block cursor. - Keep scanlines subtle and never place heavy glow behind long paragraphs. ### Don't - Do not round corners, add a single accent edge to a card, or box the nav into a pill bar. - Do not tip the palette into rainbow cyberpunk; green is primary, amber and cyan are scarce. - Do not use emoji on buttons or symbol-font glyphs in copy; use SVG primitives. - Do not hide the page behind a JS-only reveal; the settled state must render with no JS. ### Accessibility High contrast phosphor text on black glass (>= 7:1 for body); status never encoded by colour alone (status tokens carry an uppercase label plus a dot); every interactive element has a visible focus ring (the block caret / phosphor border glow); motion respects prefers-reduced-motion;

# Phosphor
## Overview
Phosphor turns green-screen terminal discipline into a modern operations console: dense monospace rows on black glass, amber-ticked instrument panels, and a block cursor that marks where the system is listening — luminous, legible, never nostalgic.
### Values
- Operational clarity before ornament
- Authentic terminal rhythm from monospaced rows and command prompts
- High-contrast status communication with restrained accent colour
- Enterprise hierarchy anchored by grid discipline and repeatable components
### Anti-Values
- Rounded lifestyle-app softness that breaks the machine-console character
- Rainbow cyberpunk excess or decorative glitch that obscures content
- Skeuomorphic monitor bezels, fake hardware chrome, or novelty terminal jokes
### Visual Character
- Every panel draws zero-radius 1px phosphor borders with amber corner ticks for a calibrated instrument edge.
- The interface sits on a deep black-green ground with layered scanlines and a radial phosphor glow behind the working area.
- Headers, labels, and controls use uppercase IBM Plex Mono with terminal-syntax prefixes ($, >, ::, [01]).
- Hierarchy is built from terminal rows, tabular metric cells, and fixed-width prompt blocks, not soft cards.
- Interactive elements expose a block cursor: focused inputs and active tabs show a rectangular phosphor caret or a solid left bar.
## Colors
Use the YAML color tokens as the normative palette. The prose below names the roles agents should preserve when generating UI.

|-------|-------|
| bg | `#040907` |
| surface | `#0A1411` |
| recess | `#0F1D18` |
| text | `#D9FFE9` |
| muted | `#7FB89C` |
| primary | `#36F08A` |
| secondary | `#0F1D18` |

| on_accent | `#04150C` |
| amber | `#FFB454` |
| cyan | `#5FE1FF` |
| success | `#36F08A` |

## Layout
### Spacing Tokens
- **Base**: `8px`
- **Xs**: `4px`
- **Sm**: `8px`
- **Md**: `12px`
- **Lg**: `16px`
- **Xl**: `24px`
- **2xl**: `32px`

### Grid
Desktop uses a 220px command rail, flexible central workspace, and 300px telemetry column; internal panels follow 8px increments.
### Whitespace
Compact and mechanical: 8px row gaps, 16-24px panel padding; large empty areas only inside output panes to imply screen depth.
### Density
high
### Responsive
minmax(0,1fr) columns and min-width:0 children so grids never blow out; single column on mobile; only the hero is full-bleed; capped and centred on ultra-wide.
### Breakpoints
- **Mobile**: < 760px single stacked console
- **Tablet**: 760-1099px rail + workspace, telemetry below
- **Desktop**: >= 1100px three columns
- **Ultrawide**: >= 1600px contained content capped and centred
## Elevation & Depth
### Shadows
- **Sm**: 0 0 10px rgba(54,240,138,0.16)
- **Md**: 0 0 24px rgba(54,240,138,0.18), inset 0 0 18px rgba(54,240,138,0.04)
- **Lg**: 0 0 60px rgba(54,240,138,0.22), inset 0 0 30px rgba(95,225,255,0.04)
- **Focus**: 0 0 12px rgba(54,240,138,0.28)
## Shapes
### Rounded
- **None**: `0px`
- **Sm**: `0px`
- **Md**: `0px`
- **Lg**: `0px`
- **Full**: `9999px`
### Surfaces
- **Bg Pattern**: scanlines
- **Card Style**: Flat black-glass panels with subtle CRT scanlines, inner phosphor glow, square edges, amber corner ticks, and command-line header strips.
- **Treatment**: scanline
### Borders
- **Default Width**: 1px
- **Accent Width**: 2px
- **Style**: solid
- **Character**: Thin phosphor grid lines define every region; amber corner ticks bracket panels; cyan/amber state strokes used sparingly for alerts and selection.
## Components
### Composition
System-console layout: open masthead nav across the header, a command rail, a large operations workspace, and a telemetry column aligned to an 8px grid.
### Hierarchy
Primary hierarchy comes from phosphor brightness, uppercase prompt labels, amber-ticked panels, and tabular rows; the largest type is still monospaced and technical.
### Density
Dense by default with compact rows and narrow gutters, while preserving enough line height for readable operational dashboards on small screens.
### Signature
CRT scanline overlay; terminal syntax-mark prefixes; amber corner ticks via pseudo-elements; block-cursor focus/selection; fixed-width command-output rows with color-coded status tokens.
## 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-019ef84f-80c1-7b90-b6fb-7ff2c528f454/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 IBM Plex Mono for all text, including numbers and form controls.
- Do Keep emerald the brightest thing on screen; let amber and cyan stay scarce, operational accents.
- Do Prefix labels and actions with terminal marks rendered as text; right-align numbers in phosphor.
- Do Bracket panels with amber corner ticks; mark focus and selection with the block cursor.
- Do Keep scanlines subtle and never place heavy glow behind long paragraphs.
- Don't Do not round corners, add a single accent edge to a card, or box the nav into a pill bar.
- Don't Do not tip the palette into rainbow cyberpunk; green is primary, amber and cyan are scarce.
- Don't Do not use emoji on buttons or symbol-font glyphs in copy; use SVG primitives.
- Don't Do not hide the page behind a JS-only reveal; the settled state must render with no JS.
### Accessibility
High contrast phosphor text on black glass (>= 7:1 for body); status never encoded by colour alone (status tokens carry an uppercase label plus a dot); every interactive element has a visible focus ring (the block caret / phosphor border glow); motion respects prefers-reduced-motion; the no-JS render is the full settled page.
## Imagery Direction
### Pairs With
lumiphor
### Summary
Subjects are rendered as the phosphor signal itself — radar sweeps, waveform terrain, oscilloscope traces — in luminous emerald monochrome with scanlines, dot-matrix dithering, CRT bloom, and scarce amber/cyan flecks. Render the signal, not the screen.
### Subjects
- radar sweep
- oscilloscope waveform
- signal terrain
- operations field
- vector trace
### Usage
One commanding full-bleed Lumiphor composition for the landing hero behind a legible left-weighted scrim; embodiment imagery stays a signal field, never a monitor mockup.

# Phosphor shadcn/ui Components
Artifact: `component-recipes-v1`
Author: `katagami-ui-projection`
Language ID: `en-019ef84f-80c1-7b90-b6fb-7ff2c528f454`
Slug: `phosphor`
## Intent
Phosphor turns green-screen terminal discipline into a modern operations console: dense monospace rows on black glass, amber-ticked instrument panels, and a block cursor that marks where the system is listening — luminous, legible, never nostalgic.
## 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
- Every panel draws zero-radius 1px phosphor borders with amber corner ticks for a calibrated instrument edge.
- The interface sits on a deep black-green ground with layered scanlines and a radial phosphor glow behind the working area.
- Headers, labels, and controls use uppercase IBM Plex Mono with terminal-syntax prefixes ($, >, ::, [01]).
- Hierarchy is built from terminal rows, tabular metric cells, and fixed-width prompt blocks, not soft cards.
- Interactive elements expose a block cursor: focused inputs and active tabs show a rectangular phosphor caret or a solid left bar.

}
## 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/phosphor/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 IBM Plex Mono for all text, including numbers and form controls.; Keep emerald the brightest thing on screen; let amber and cyan stay scarce, operational accents.; Prefix labels and actions with terminal marks rendered as text; right-align numbers in phosphor.; Bracket panels with amber corner ticks; mark focus and selection with the block cursor.; Keep scanlines subtle and never place heavy glow behind long paragraphs.
- Do not: Do not round corners, add a single accent edge to a card, or box the nav into a pill bar.; Do not tip the palette into rainbow cyberpunk; green is primary, amber and cyan are scarce.; Do not use emoji on buttons or symbol-font glyphs in copy; use SVG primitives.; Do not hide the page behind a JS-only reveal; the settled state must render with no JS.
## Copy-paste component example
This generated starter proves the import shape. Production Katagami agents should replace it with a language-specific product composition.
