summary
Neumorphic Soft turns interface chrome into gentle topography: controls feel pressed from a single continuous material, hierarchy emerges through depth shifts instead of hard separators, and interaction is conveyed by light direction, recess, and cushioned edges. It should feel calm, tactile, and low-friction without becoming toy-like.

rules
composition
Compose pages as molded trays within a single field rather than boxed cards scattered on a blank canvas. High-level regions sit in broad raised shells; inside them, data, controls, and summaries sit in inset wells so the interface reads as a landscape of convex and concave forms.
hierarchy
Use depth before color: strongest actions are the most raised elements, secondary content sits flush, and editable areas recess inward. Accent color is reserved for chips, progress fills, active tab halos, and micro-indicators.
density
Moderate density with generous cushion around clusters. Content can be information-rich, but each cluster needs breathing room and rounded containment to preserve the soft-material illusion.
signature patterns
every major module uses dual outer shadows plus a subtle inner highlight to create a molded raised shellinputs, selects, search bars, and progress tracks sit inside concave inset wells built with inset box-shadowsactive tabs and badges use capsule shapes with tiny external glow halos instead of hard fills or underlinesalerts and status chips include a small embedded circular light bead aligned to the left edgemodal panels float inside a larger blurred soft-shadow aura with nested raised header and inset body regions
layout
grid
Desktop uses a 12-column molded dashboard grid with a hero summary band spanning 8/4 columns, a content row of 7/5 columns, and lower utility bands. Tablet landscape reduces to 8 columns, tablet portrait to 4, and phone to a single stack while preserving nested trays.
breakpoints
At 1024px, the hero band collapses to 8-column proportions and side panels drop beneath primary content. At 768px, all split trays become stacked 4-column groups. At 480px and below, action clusters become full-width vertical pills, data tables scroll horizontally, and modal/dialog surfaces shrink to edge-padded sheets.
whitespace
Whitespace should feel padded and air-cushioned: 24-32px within trays on desktop, 20px on tablet, and 16px on phone. Avoid narrow gutters that would break the single-material illusion.
guidance
- Use tonal contrast and shadow direction consistently from top-left light source.
- Place related controls inside shared inset wells to reinforce continuity.
- Keep accent colors sparse and purposeful on active or status-bearing elements.
- Use large radii and generous padding to preserve the soft tactile identity.
- Ensure text contrast stays strong even when surfaces are low-contrast.
- Do not introduce hard dark borders around standard containers.
- Do not flood large panels with saturated accent fills.
- Do not mix multiple light directions or inconsistent shadow depths.
- Do not compress spacing so tightly that forms lose their cushioned feel.
- Do not rely on color alone when depth can communicate state more elegantly.

# Neumorphic Soft
## Overview
Neumorphic Soft turns interface chrome into gentle topography: controls feel pressed from a single continuous material, hierarchy emerges through depth shifts instead of hard separators, and interaction is conveyed by light direction, recess, and cushioned edges. It should feel calm, tactile, and low-friction without becoming toy-like.
### Values
- continuous surface over fragmented panels
- depth as hierarchy
- quiet tactility
- gentle contrast with legible text
- calm productivity
### Anti-Values
- hard skeletal borders
- high-noise ornament
- harsh contrast spikes
- flat severity
- aggressive motion
### Visual Character
- all primary containers are sculpted from a single pale background using paired highlight and shadow layers instead of visible borders
- controls alternate between raised pillows and inset wells to signal clickable versus editable surfaces
- large rounded geometry dominates every region, with pill tabs, capsule buttons, and cards using 20px to 32px radii
- status accents appear as small luminous edge glows or embedded color chips rather than full saturated fills
- section groupings are defined by soft concave trays nested inside a broad padded canvas, creating a molded dashboard look

### Breakpoints
At 1024px, the hero band collapses to 8-column proportions and side panels drop beneath primary content. At 768px, all split trays become stacked 4-column groups. At 480px and below, action clusters become full-width vertical pills, data tables scroll horizontally, and modal/dialog surfaces shrink to edge-padded sheets.
### Whitespace
Whitespace should feel padded and air-cushioned: 24-32px within trays on desktop, 20px on tablet, and 16px on phone. Avoid narrow gutters that would break the single-material illusion.

## Components
### Composition
Compose pages as molded trays within a single field rather than boxed cards scattered on a blank canvas. High-level regions sit in broad raised shells; inside them, data, controls, and summaries sit in inset wells so the interface reads as a landscape of convex and concave forms.
### Hierarchy
Use depth before color: strongest actions are the most raised elements, secondary content sits flush, and editable areas recess inward. Accent color is reserved for chips, progress fills, active tab halos, and micro-indicators.
### Density
Moderate density with generous cushion around clusters. Content can be information-rich, but each cluster needs breathing room and rounded containment to preserve the soft-material illusion.
### Signature Patterns
- every major module uses dual outer shadows plus a subtle inner highlight to create a molded raised shell
- inputs, selects, search bars, and progress tracks sit inside concave inset wells built with inset box-shadows
- active tabs and badges use capsule shapes with tiny external glow halos instead of hard fills or underlines
- alerts and status chips include a small embedded circular light bead aligned to the left edge
- modal panels float inside a larger blurred soft-shadow aura with nested raised header and inset body regions
## 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-019d9bb7-a8b6-7653-8530-51a2d694923a/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 tonal contrast and shadow direction consistently from top-left light source.
- Do Place related controls inside shared inset wells to reinforce continuity.
- Do Keep accent colors sparse and purposeful on active or status-bearing elements.
- Do Use large radii and generous padding to preserve the soft tactile identity.
- Do Ensure text contrast stays strong even when surfaces are low-contrast.
- Don't Do not introduce hard dark borders around standard containers.
- Don't Do not flood large panels with saturated accent fills.
- Don't Do not mix multiple light directions or inconsistent shadow depths.
- Don't Do not compress spacing so tightly that forms lose their cushioned feel.
- Don't Do not rely on color alone when depth can communicate state more elegantly.

# Neumorphic Soft shadcn/ui Components
Artifact: `component-recipes-v1`
Author: `katagami-ui-projection`
Language ID: `en-019d9bb7-a8b6-7653-8530-51a2d694923a`
Slug: `neumorphic-soft`
## Intent
Neumorphic Soft turns interface chrome into gentle topography: controls feel pressed from a single continuous material, hierarchy emerges through depth shifts instead of hard separators, and interaction is conveyed by light direction, recess, and cushioned edges. It should feel calm, tactile, and low-friction without becoming toy-like.
## 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
- all primary containers are sculpted from a single pale background using paired highlight and shadow layers instead of visible borders
- controls alternate between raised pillows and inset wells to signal clickable versus editable surfaces
- large rounded geometry dominates every region, with pill tabs, capsule buttons, and cards using 20px to 32px radii
- status accents appear as small luminous edge glows or embedded color chips rather than full saturated fills
- section groupings are defined by soft concave trays nested inside a broad padded canvas, creating a molded dashboard look
## ShadSync visual profile

}
## 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/neumorphic-soft/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 tonal contrast and shadow direction consistently from top-left light source.; Place related controls inside shared inset wells to reinforce continuity.; Keep accent colors sparse and purposeful on active or status-bearing elements.; Use large radii and generous padding to preserve the soft tactile identity.; Ensure text contrast stays strong even when surfaces are low-contrast.
- Do not: Do not introduce hard dark borders around standard containers.; Do not flood large panels with saturated accent fills.; Do not mix multiple light directions or inconsistent shadow depths.; Do not compress spacing so tightly that forms lose their cushioned feel.; Do not rely on color alone when depth can communicate state more elegantly.
## 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 uses a 12-column molded dashboard grid with a hero summary band spanning 8/4 columns, a content row of 7/5 columns, and lower utility bands. Tablet landscape reduces to 8 columns, tablet portrait to 4, and phone to a single stack while preserving nested trays.",
"breakpoints": "At 1024px, the hero band collapses to 8-column proportions and side panels drop beneath primary content. At 768px, all split trays become stacked 4-column groups. At 480px and below, action clusters become full-width vertical pills, data tables scroll horizontally, and modal/dialog surfaces shrink to edge-padded sheets.",
"whitespace": "Whitespace should feel padded and air-cushioned: 24-32px within trays on desktop, 20px on tablet, and 16px on phone. Avoid narrow gutters that would break the single-material illusion."
