A portable design language for agents: download the markdown first, then inspect the preview, tokens, and rules as needed.
Portable DESIGN.md source of truth for most agents and apps.
Compose every screen as a bound atlas of plates: each module is opened by a recessed left binding-spine with a vertical plate code, marked with corner registration crosses, and hung on a measured tick-rule baseline — the page, never the floating card, is the unit.
Set display type as engraved plate captions — a measured tick-rule folded in above a high-optical-contrast Fraunces line, then a mono coordinate caption — so readers scan from plate caption to evidence to fine-grain mono readings without losing place.
High information density is allowed, but the measured rule paces it: ticks tighten inside a register and open between spreads, and narrative blocks stay separated from technical blocks by space rather than emptiness.
Every module opens with the binding-spine (recessed gutter + vertical mono plate code) and is registered by corner fiducial crosses; layouts use a centred contact-sheet of equal plates on one baseline; primary actions are a single filled teal instrument, the rest quiet keyline outlines.
A centred contact-sheet grid of equal plates hung on one baseline (typically 3 columns), with a wide-chart-plus-narrow-readings-rail split on dashboards; contained content caps at ~1300–1480px and centres.
Whitespace works like a catalogue's pacing: tighter inside a register, generous between spreads, always paced by the measured rule rather than empty emptiness.
Dense but catalogued — evidence is edited, not dumped; blocks are separated by space and the measured rule.
Stacks to a single column on mobile (spine narrows, nav links drop); only the full-bleed hero spans 100vw; tables scroll horizontally; ultra-wide caps and centres contained content.
vitrine
Backlit astronomical specimens presented as archival plates: a single subject filling the frame, emerging from a charcoal-indigo ground, rim-lit cool (teal) on one edge and warm (gold) on the other. Presented, never framed.
One full-bleed specimen plate at the landing hero; specimen crops inside plate modules. Always edge-to-edge with the dual cool/warm rim; no glass case, frame, paper border, or text on the plate.
# Ephemeris ## Philosophy A dark-mode design language that catalogues speculative operational telemetry like a bound astronomical plate-book: every reading is a numbered, spined, registration-marked plate, hung on a measured baseline with the calm of a printing institute rather than the noise of a control room. ### Values - Edited evidence over dumped feeds — the page, not the widget, is the unit - Long-form readability inside dense technical scenes - Speculative atmosphere carried by structure, registration, and calibrated indigo backlight ### Anti-Values - Floating, arbitrarily sized cards with no binding - Neon flood, or a flat black void with a sci-fi palette pasted on - Ornament that does not register, measure, or bind ### Visual Character - Every module is opened by a recessed left binding-spine carrying a vertical plate code, as if torn from a bound volume — the atlas page, not the app card, is the recurring unit. - Corner registration crosses mark each plate, meaning alignment to the press the way a printer seated a plate true on the bed. - A measured tick-rule paces every screen — a short bright teal segment against a longer quiet violet ruling — tightening inside data and opening between spreads, never collapsing to empty space. - A deep indigo observatory-dome ground stays gently backlit, interrupted only by two localized signal accents — glacier teal and aureate gold — plus a minor rose for held states, so the interface feels atmospheric but never neon. ## Tokens ### Colors | Name | Value | |------|-------| | bg | `#161033` | | surface | `#1E1746` | | surface_2 | `#120D29` | | text | `#F2EEFF` | | muted | `#A29AC8` | | border | `#312758` | | rule | `#4B3C84` | | accent | `#7FE3D2` | | accent_warm | `#E7B24C` | | accent_rose | `#E07AB0` | | on_accent | `#120D29` | | primary | `#7FE3D2` | | secondary | `#E7B24C` | | success | `#7FE3D2` | | warning | `#E7B24C` | | error | `#E07AB0` | | info | `#9FB6FF` | ### Typography - **Base Size**: 17px - **Body Font**: Spline Sans - **Heading Font**: Fraunces - **Mono Font**: Spline Sans Mono - **Heading Weight**: 500 - **Heading Transform**: none - **Letter Spacing**: -0.015em - **Line Height**: 1.6 - **Google Fonts Url**: https://fonts.googleapis.com/css2?family=Fraunces:ital,opsz,wght@0,9..144,400;0,9..144,500;0,9..144,600;1,9..144,500&family=Spline+Sans:wght@400;500;600;700&family=Spline+Sans+Mono:wght@400;500;600&display=swap ### Radii - **None**: 0 - **Full**: 9999px ### Shadows - **Sm**: 0 0 0 1px rgba(127,227,210,0.05), 0 10px 28px rgba(7,5,20,0.45) - **Md**: 0 0 0 1px rgba(127,227,210,0.07), 0 22px 52px rgba(7,5,20,0.55) - **Lg**: 0 0 0 1px rgba(127,227,210,0.09), 0 34px 90px rgba(7,5,20,0.66) ### Spacing - **Base**: 8px - **Scale**: [4,8,12,16,24,32,48,64,96] ### Surfaces - **Treatment**: gradient - **Card Style**: Layered indigo plate fields with a faint radial top-glow, like an illuminated archival plate behind glass; opened by a recessed left binding-spine and marked with corner registration crosses.

# Ephemeris
## Overview
A dark-mode design language that catalogues speculative operational telemetry like a bound astronomical plate-book: every reading is a numbered, spined, registration-marked plate, hung on a measured baseline with the calm of a printing institute rather than the noise of a control room.
### Values
- Edited evidence over dumped feeds — the page, not the widget, is the unit
- Long-form readability inside dense technical scenes
- Speculative atmosphere carried by structure, registration, and calibrated indigo backlight
### Anti-Values
- Floating, arbitrarily sized cards with no binding
- Neon flood, or a flat black void with a sci-fi palette pasted on
- Ornament that does not register, measure, or bind
### Visual Character
- Every module is opened by a recessed left binding-spine carrying a vertical plate code, as if torn from a bound volume — the atlas page, not the app card, is the recurring unit.
- Corner registration crosses mark each plate, meaning alignment to the press the way a printer seated a plate true on the bed.
- A measured tick-rule paces every screen — a short bright teal segment against a longer quiet violet ruling — tightening inside data and opening between spreads, never collapsing to empty space.
- A deep indigo observatory-dome ground stays gently backlit, interrupted only by two localized signal accents — glacier teal and aureate gold — plus a minor rose for held states, so the interface feels atmospheric but never neon.
## Colors
Use the YAML color tokens as the normative palette. The prose below names the roles agents should preserve when generating UI.

## Typography
- **Headline-Lg**: Fraunces, 2.075rem, weight 700, line-height 1.1.
- **Headline-Md**: Fraunces, 1.66rem, weight 600, line-height 1.15.
- **Body-Md**: Spline Sans, 17px, weight 400, line-height 1.5.
- **Label-Md**: Spline Sans Mono, 0.75rem, weight 600, line-height 1.
## Layout
### Spacing Tokens
- **Base**: `8px`
- **Xs**: `4px`
- **Sm**: `8px`
- **Md**: `12px`
- **Lg**: `16px`
- **Xl**: `24px`
- **2xl**: `32px`
- **3xl**: `48px`
- **4xl**: `64px`
- **Step-8**: `96px`
### Grid
A centred contact-sheet grid of equal plates hung on one baseline (typically 3 columns), with a wide-chart-plus-narrow-readings-rail split on dashboards; contained content caps at ~1300–1480px and centres.
### Whitespace
Whitespace works like a catalogue's pacing: tighter inside a register, generous between spreads, always paced by the measured rule rather than empty emptiness.
### Density
Dense but catalogued — evidence is edited, not dumped; blocks are separated by space and the measured rule.
### Responsive
Stacks to a single column on mobile (spine narrows, nav links drop); only the full-bleed hero spans 100vw; tables scroll horizontally; ultra-wide caps and centres contained content.
### Breakpoints
- **Mobile**: 390px single column, narrowed binding-spine, full-width controls, horizontally scrollable register
- **Tablet**: 768px two-column contact sheet, stacked dashboard split
- **Desktop**: 1440px three-column contact sheet, wide-plus-rail dashboard
- **Ultrawide**: 2560px caps and centres contained content; only the hero spans full width
## Elevation & Depth
### Shadows
- **Sm**: 0 0 0 1px rgba(127,227,210,0.05), 0 10px 28px rgba(7,5,20,0.45)
- **Md**: 0 0 0 1px rgba(127,227,210,0.07), 0 22px 52px rgba(7,5,20,0.55)
- **Lg**: 0 0 0 1px rgba(127,227,210,0.09), 0 34px 90px rgba(7,5,20,0.66)
## Shapes
### Rounded
- **None**: `0px`
- **Full**: `9999px`
### Surfaces
- **Treatment**: gradient
- **Card Style**: Layered indigo plate fields with a faint radial top-glow, like an illuminated archival plate behind glass; opened by a recessed left binding-spine and marked with corner registration crosses. Never flat black, never a hard drop shadow.
- **Bg Pattern**: radial-backlight
### Borders
- **Default Width**: 1px
- **Accent Width**: 2px
- **Style**: solid
- **Character**: Quiet violet hairline keylines and a brighter measured rule; teal/gold keylines mark active states and section spines. No grey decorative borders, no single accent edge on a card.
## Components
### Composition
Compose every screen as a bound atlas of plates: each module is opened by a recessed left binding-spine with a vertical plate code, marked with corner registration crosses, and hung on a measured tick-rule baseline — the page, never the floating card, is the unit.
### Hierarchy
Set display type as engraved plate captions — a measured tick-rule folded in above a high-optical-contrast Fraunces line, then a mono coordinate caption — so readers scan from plate caption to evidence to fine-grain mono readings without losing place.
### Density
High information density is allowed, but the measured rule paces it: ticks tighten inside a register and open between spreads, and narrative blocks stay separated from technical blocks by space rather than emptiness.
### Signature
Every module opens with the binding-spine (recessed gutter + vertical mono plate code) and is registered by corner fiducial crosses; layouts use a centred contact-sheet of equal plates on one baseline; primary actions are a single filled teal instrument, the rest quiet keyline outlines.
## 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-019ef8fa-8d41-7f10-b170-0f42d9dacf09/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 Open every module with the binding-spine and register it with corner crosses.
- Do Pace the page with the measured rule — tighten ticks in data, open them between spreads.
- Do Keep teal and gold localized to headings, signals, and active controls so reading comfort stays high.
- Do Set display type as engraved plate captions in Fraunces; keep body Spline Sans and data in mono.
- Don't Float arbitrarily sized cards or break the contact-sheet baseline.
- Don't Flood the interface with neon or drop to a flat black void.
- Don't Add ornament that does not register, measure, or bind.
- Don't Use symbol glyphs (arrows, triangles) in copy — draw them as SVG primitives.
### Accessibility
Body 17px; #F2EEFF on #161033 clears WCAG AA. Focus states are explicit teal keylines. Status is never colour-only — badges carry a word (Filed / Review / Held). Motion is gated and respects prefers-reduced-motion.
## Imagery Direction
### Pairs With
vitrine
### Summary
Backlit astronomical specimens presented as archival plates: a single subject filling the frame, emerging from a charcoal-indigo ground, rim-lit cool (teal) on one edge and warm (gold) on the other. Presented, never framed.
### Subjects
- armillary sphere
- orrery
- nebula core
- telescope mirror
- celestial globe
- meteorite specimen
### Usage
One full-bleed specimen plate at the landing hero; specimen crops inside plate modules. Always edge-to-edge with the dual cool/warm rim; no glass case, frame, paper border, or text on the plate.

# Ephemeris shadcn/ui Components
Artifact: `component-recipes-v1`
Author: `katagami-ui-projection`
Language ID: `en-019ef8fa-8d41-7f10-b170-0f42d9dacf09`
Slug: `ephemeris`
## Intent
A dark-mode design language that catalogues speculative operational telemetry like a bound astronomical plate-book: every reading is a numbered, spined, registration-marked plate, hung on a measured baseline with the calm of a printing institute rather than the noise of a control room.
## 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 module is opened by a recessed left binding-spine carrying a vertical plate code, as if torn from a bound volume — the atlas page, not the app card, is the recurring unit.
- Corner registration crosses mark each plate, meaning alignment to the press the way a printer seated a plate true on the bed.
- A measured tick-rule paces every screen — a short bright teal segment against a longer quiet violet ruling — tightening inside data and opening between spreads, never collapsing to empty space.
- A deep indigo observatory-dome ground stays gently backlit, interrupted only by two localized signal accents — glacier teal and aureate gold — plus a minor rose for held states, so the interface feels atmospheric but never neon.

## 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/ephemeris/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: Open every module with the binding-spine and register it with corner crosses.; Pace the page with the measured rule — tighten ticks in data, open them between spreads.; Keep teal and gold localized to headings, signals, and active controls so reading comfort stays high.; Set display type as engraved plate captions in Fraunces; keep body Spline Sans and data in mono.
- Do not: Float arbitrarily sized cards or break the contact-sheet baseline.; Flood the interface with neon or drop to a flat black void.; Add ornament that does not register, measure, or bind.; Use symbol glyphs (arrows, triangles) in copy — draw them as SVG primitives.
## Copy-paste component example
This generated starter proves the import shape. Production Katagami agents should replace it with a language-specific product composition.
