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.
Build the screen around arched bays and one dominant tally artifact: each measure is a self-contained arch-topped bay, and the vote rises as a registered stack of flat color blocks. Memphis references form zones and state markers, never floating confetti.
Archivo Expanded for public-facing declarations, Atkinson Hyperlegible for task content, Space Mono for codes, measure numbers, statuses, and numeric ledgers. Important items gain crowns and register offsets before extra font weight.
Balanced: content panels may be information-rich, but every bright panel needs adjacent ink breathing room and no more than three dominant brights in a viewport.
Arched bays that step like a city elevation; the tally stack of registered blocks with a lemon crown on a cleared measure; one flat down-right misregistration offset on slabs and controls; structural ownership pillars encoding caucus across cards, rows, and dialogs.
Twelve-column desktop feel with controlled half-cell offsets so bays step like a playful city elevation while controls stay aligned; a centered, symmetric civic composition. Tablet collapses to two columns, mobile to one column with tabs becoming horizontal chips.
Ink-navy margins as silence between chroma blocks; at least 24px between unrelated slabs; bright underlays behind no more than one third of the viewport.
balanced
Renders from ~390px mobile to 2560px+ ultra-wide; single-column stack on mobile with non-essential nav and table columns hidden; capped, centered content on ultra-wide with only the hero spanning 100vw.
quoin
Flat hard-edged postmodern screenprint (the Quoin technique) applied to civic forum subjects on a dark ink-navy night ground: registered color planes, even-weight black construction lines, one flat down-right misregistration offset, mint grid, flat color disk, lilac arch fragments, checkerboard corner keys.
Hero is a full-bleed colonnade hall in the Quoin technique; section art stays structural (grid, disk, arch fragments). Keep three brights dominant; mint and lilac structural only. End image prompts with 'NO text, NO letters, NO logos.'

# Rostra
## Overview
A referendum operating surface that counts the vote as architecture. Conceived in parallel to the Civic Arcade Pluralism brief: Memphis geometry and quoted postmodern facades turned into a usable civic tool, but moved into a forum at night. Every measure rises in its own arched bay; the vote accumulates as a registered tally stack of flat color blocks; a lemon crown locks on top the instant a measure clears quorum. Plural, high-chroma, witty, held inside a strict interaction grid so a loud floor still reads as one system.
### Values
- A vote you can read like a building
- Plural civic voices held by one strict interaction grid
- Visual wit that maps to navigation, ownership, status, or state
- High-chroma optimism lit over a dark forum-night ground
- Historic quotation translated into interface structure
### Anti-Values
- Generic dark SaaS dashboards with neon accents pasted on
- Random Memphis confetti that does not organize hierarchy
- Soft drop shadows, glows, or glassmorphism on civic chrome
- A single colored edge as the only accent on a card
- Defaulting to a plain white or warm off-white ground
## Colors
Use the YAML color tokens as the normative palette. The prose below names the roles agents should preserve when generating UI.
| Token | Value |
|-------|-------|
| bg | `#0A0E2E` |
| surface | `#121A4A` |
| recess | `#080B22` |
| text | `#F4F1FF` |
| muted | `#9AA0D6` |
| border | `#000510` |
| on_accent | `#080B22` |
| accent | `#2D5BFF` |
| accent_2 | `#FF2E55` |

## Typography
- **Headline-Lg**: Archivo Expanded, 2.075rem, weight 700, line-height 1.1.
- **Headline-Md**: Archivo Expanded, 1.66rem, weight 600, line-height 1.15.
- **Body-Md**: Atkinson Hyperlegible, 17px, weight 400, line-height 1.55.
- **Label-Md**: Space 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
Twelve-column desktop feel with controlled half-cell offsets so bays step like a playful city elevation while controls stay aligned; a centered, symmetric civic composition. Tablet collapses to two columns, mobile to one column with tabs becoming horizontal chips.
### Whitespace
Ink-navy margins as silence between chroma blocks; at least 24px between unrelated slabs; bright underlays behind no more than one third of the viewport.
### Density
balanced
### Responsive
Renders from ~390px mobile to 2560px+ ultra-wide; single-column stack on mobile with non-essential nav and table columns hidden; capped, centered content on ultra-wide with only the hero spanning 100vw.
### Breakpoints
- **Mobile**: 390px
- **Tablet**: 760px
- **Desktop**: 1080px
- **Wide**: 1480px
## Elevation & Depth
### Shadows
- **Character**: one flat one-directional misregistration offset (a hard zero-blur color block down-right), never a soft drop shadow or glow
- **Sm**: 3px 3px 0 #000510
- **Md**: 6px 6px 0 #2D5BFF
- **Lg**: 6px 6px 0 #FF2E55
## Shapes
### Rounded
- **None**: `0px`
- **Sm**: `0px`
- **Md**: `0px`
- **Arch**: `24px`
- **Full**: `9999px`
### Surfaces
- **Bg Pattern**: deep ink-navy night ground under a faint mint construction grid, with a lemon civic moon and lilac arch fragments used only to zone content
- **Card Style**: arch-topped slab (24px top radius), flat surface color, even-weight black construction-line border, one flat register offset; a lemon crown marks a cleared measure
- **Treatment**: flat ink fields over the navy hall with controlled geometric zoning; brights read as lit civic signage, never accents on white
### Borders
- **Default Width**: 2.5px
- **Accent Width**: 3.5px
- **Style**: solid
- **Character**: even-weight black construction lines; state shown by crowns and structural ownership pillars, never a lone colored side edge
## Components
### Composition
Build the screen around arched bays and one dominant tally artifact: each measure is a self-contained arch-topped bay, and the vote rises as a registered stack of flat color blocks. Memphis references form zones and state markers, never floating confetti.
### Hierarchy
Archivo Expanded for public-facing declarations, Atkinson Hyperlegible for task content, Space Mono for codes, measure numbers, statuses, and numeric ledgers. Important items gain crowns and register offsets before extra font weight.
### Density
Balanced: content panels may be information-rich, but every bright panel needs adjacent ink breathing room and no more than three dominant brights in a viewport.
### Signature
Arched bays that step like a city elevation; the tally stack of registered blocks with a lemon crown on a cleared measure; one flat down-right misregistration offset on slabs and controls; structural ownership pillars encoding caucus across cards, rows, and dialogs.
## 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-019ef993-68bc-78a0-83df-c1574954c094/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 Anchor every playful move to navigation, ownership, status, or hierarchy.
- Do Keep cobalt, cherry, and lemon as the bright trio; use mint and lilac as structural underlay and abstain/coalition markers.
- Do Mark a cleared measure with a lemon crown; show ownership with a structural pillar.
- Do Use even-weight black construction lines and mono labels so plural forms feel like one system.
- Do Make responsive layouts re-stack into a clear measure-reading order.
- Don't Scatter Memphis shapes, arches, or crowns as decorative filler without workflow meaning.
- Don't Use soft drop shadows, glows, glassmorphism, or blurred SaaS cards on civic chrome.
- Don't Put a single colored edge as the only accent on a card, or round corners arbitrarily.
- Don't Let more than three brights dominate one surface, or default to a plain white ground.
### Accessibility
High contrast throughout (near-white ink on the navy ground, ink on cobalt/cherry/lemon); body text 17px+, table rows 14.5px+; every form control explicitly styled with a visible cobalt focus ring; motion respects prefers-reduced-motion and the settled state renders with no JavaScript.
## Imagery Direction
### Pairs With
quoin
### Summary
Flat hard-edged postmodern screenprint (the Quoin technique) applied to civic forum subjects on a dark ink-navy night ground: registered color planes, even-weight black construction lines, one flat down-right misregistration offset, mint grid, flat color disk, lilac arch fragments, checkerboard corner keys.
### Subjects
- a postmodern colonnade tally hall
- stacked ballot-block columns
- a civic speaking rostrum
- arched proposal bays
- a forum at night under a lemon moon
### Usage
Hero is a full-bleed colonnade hall in the Quoin technique; section art stays structural (grid, disk, arch fragments). Keep three brights dominant; mint and lilac structural only. End image prompts with 'NO text, NO letters, NO logos.'

# Rostra shadcn/ui Components
Artifact: `component-recipes-v1`
Author: `katagami-ui-projection`
Language ID: `en-019ef993-68bc-78a0-83df-c1574954c094`
Slug: `rostra`
## Intent
A referendum operating surface that counts the vote as architecture. Conceived in parallel to the Civic Arcade Pluralism brief: Memphis geometry and quoted postmodern facades turned into a usable civic tool, but moved into a forum at night. Every measure rises in its own arched bay; the vote accumulates as a registered tally stack of flat color blocks; a lemon crown locks on top the instant a measure clears quorum. Plural, high-chroma, witty, held inside a strict interaction grid so a loud floor still reads as one system.
## 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
- Make the source language's structural identity visible in every component state.
## ShadSync visual profile
{
"family": "system",
"material": "flat",
"contour": "pebble",
"border": "solid",
"underlay": true,
"grain": false,
"stickerBadges": false,
"motion": "still",
"density": "balanced",
"accents": [

"secondary",

]
}
## 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/rostra/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: Anchor every playful move to navigation, ownership, status, or hierarchy.; Keep cobalt, cherry, and lemon as the bright trio; use mint and lilac as structural underlay and abstain/coalition markers.; Mark a cleared measure with a lemon crown; show ownership with a structural pillar.; Use even-weight black construction lines and mono labels so plural forms feel like one system.; Make responsive layouts re-stack into a clear measure-reading order.
- Do not: Scatter Memphis shapes, arches, or crowns as decorative filler without workflow meaning.; Use soft drop shadows, glows, glassmorphism, or blurred SaaS cards on civic chrome.; Put a single colored edge as the only accent on a card, or round corners arbitrarily.; Let more than three brights dominate one surface, or default to a plain white ground.
