# Loess shadcn/ui Components

Artifact: `component-recipes-v1`
Author: `katagami-ui-projection`
Language ID: `en-019efd5c-3c7b-7442-b32e-0bc9ed7ad995`
Slug: `loess`

## Intent

Loess presses the whole interface from one continuous bed of warm sediment and lets a single low light do the work borders usually do: raised plateaus read as action, incised wells read as input, and a thin terracotta seam catches the lip of an edge wherever colour earns a place. Depth is the hierarchy; light is the only edge. It refines the neumorphic idea and corrects what made it muddy — the grey-blue wash, low contrast, toy softness — with a bright warm clay ground, deep-umber text, and an accent rationed to a lit seam rather than a pastel fill.

## 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 surface is sculpted from one warm-clay field using a paired highlight/shadow set instead of borders, lit from a single upper-left rake
- controls raise into pillows to act and sink into incised wells to receive input, so depth tells you what a thing is
- large soft fillets dominate every region; radii are 16 or 24px and nothing has a sharp corner
- the terracotta accent appears only as a thin lit seam on an incised lip and as small glowing status beads, never as a flat fill
- alerts and status chips carry a small embedded light-bead at the left edge; tables and clusters live inside concave trays

## ShadSync visual profile

{
  "family": "system",
  "material": "flat",
  "contour": "pebble",
  "border": "solid",
  "underlay": false,
  "grain": false,
  "stickerBadges": true,
  "motion": "lift",
  "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/loess/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: Carve hierarchy with elevation before reaching for colour.; Keep one consistent light direction (upper-left) across every element.; Reserve the terracotta accent for lit incised seams, fills and small status beads.; Use large soft fillets and generous cushioned padding so the single-material illusion holds.; Keep text deep-umber for strong contrast even where surfaces are low-contrast.
- Do not: Do not draw a border or a single accent edge on any card.; Do not flood a panel with the accent as a flat fill.; Do not mix light directions or stack inconsistent shadow depths.; Do not compress padding until forms lose their cushion.; Do not swap a serif word to italic for emphasis — use a colour-pop or seam mark.

## Copy-paste component example

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

## Layout notes

{
  "grid": "Desktop is a molded dashboard / scrolling-section grid: a full-bleed relief hero, then contained sections capped at ~1140px. Dashboards use a 248px raised sidebar tray plus a fluid main column of raised plateaus and incised wells. Tablet reduces multi-column splits to stacked trays; phone is a single stack preserving the nested wells.",
  "breakpoints": "At 1080px the stat row drops to two columns and splits stack. At 860px the dashboard sidebar collapses to a horizontal top nav. At 680px all grids become a single column, the hero veil switches to a top fade for legibility, and non-essential table columns drop. At 390px action clusters go full-width, the headline clamps and wraps, and nothing overflows horizontally.",
  "whitespace": "Padded and air-cushioned: 24-32px inside trays on desktop, 20px on tablet, 16-18px on phone. Avoid narrow gutters that would break the single-material illusion.",
  "responsive": "Renders from ~390px to 2560px+; only the hero spans 100vw, contained content is capped and centred on ultra-wide.",
