summary

Cultivated-earth interface — read the screen like a soil core. A faithful refinement of Nature Distilled Organic: same earth-pigment direction and tactile material honesty, brought to standard with three highlighter accents, one coherent organic geometry, an open masthead, and a full-viewport strata hero. The ground is warm parchment, never white; text is warm bog-ink, never black.

## Components

### Composition

Content settles into warm parchment beds; cards never nest; nav sits open across the masthead; only the hero is full-bleed.

### Hierarchy

One terracotta primary action per view; secondary actions quiet; Fraunces display carries the headline, mono labels carry eyebrows.

### Density

Airy — generous whitespace, padding above every title.

### Signature

The strata gauge — every metric renders as a stacked soil core (topsoil, clay, mineral, moss root-zone); recurs as the brand seam, the divider rule, and the dashboard chart.

## 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-019ef912-8e64-73f0-8713-6535e949e63a/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 Render metrics as the strata gauge; keep the four-band order even when heights vary
- Do Use the three accents like highlighters; keep semantic colours quiet
- Do Pad above every title; let beds breathe
- Do Keep the nav open across the masthead
- Do Use warm shadows and a recessed sediment surface to separate, not borders
- Don't Use white #FFF surfaces or pure-black text
- Don't Draw a border, hairline, or single accent edge on a card
- Don't Mix in arbitrary radii outside {16,24,9999}
- Don't Stamp the strata band where no depth is read until it becomes wallpaper
- Don't Put emoji or symbol glyphs in copy or on buttons

### Accessibility

Body 17px, table rows 14.5px; bog-ink on parchment clears AA; accent text uses darkened pigment ink on soft washes; ARIA roles/states on switches and checkboxes; hero image decorative (aria-hidden); motion respects prefers-reduced-motion; all marks are SVG primitives.

## Imagery Direction

### Pairs With

loam

### Summary

Hand-painted earth-pigment strata washes with a botanical contour line on handmade-paper grain; the hero is a soil cross-section with a seedling rooting through the layers.

### Subjects

- soil cross-sections and core samples
- seedlings and root systems
- geological strata and sediment
- cultivated beds and compost
- botanical-plate plants

### Usage

Full-bleed strata hero with airy parchment negative space at the top for overlay legibility; feature spots as single centred subjects in mineral washes.

# Tilth shadcn/ui Components

Artifact: `component-recipes-v1`
Author: `katagami-ui-projection`
Language ID: `en-019ef912-8e64-73f0-8713-6535e949e63a`
Slug: `tilth`

## Intent

Cultivated-earth interface — read the screen like a soil core. A faithful refinement of Nature Distilled Organic: same earth-pigment direction and tactile material honesty, brought to standard with three highlighter accents, one coherent organic geometry, an open masthead, and a full-viewport strata hero. The ground is warm parchment, never white; text is warm bog-ink, never black.

## 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": "paper-collage",
  "material": "paper",
  "contour": "default",
  "border": "solid",
  "underlay": false,
  "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/tilth/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: Render metrics as the strata gauge; keep the four-band order even when heights vary; Use the three accents like highlighters; keep semantic colours quiet; Pad above every title; let beds breathe; Keep the nav open across the masthead; Use warm shadows and a recessed sediment surface to separate, not borders
- Do not: Use white #FFF surfaces or pure-black text; Draw a border, hairline, or single accent edge on a card; Mix in arbitrary radii outside {16,24,9999}; Stamp the strata band where no depth is read until it becomes wallpaper; Put emoji or symbol glyphs in copy or on buttons

## Copy-paste component example

This generated starter proves the import shape. Production Katagami agents should replace it with a language-specific product composition.
