+Add Next.js renderer and shadcn-svelte component library.
+
+### New:
+
+- **`@json-render/next`** -- Next.js renderer that turns JSON specs into full Next.js applications with routes, layouts, SSR, metadata, data loaders, and static generation. Client and server entry points at `@json-render/next` and `@json-render/next/server`. Includes built-in `Link`, `Slot`, error boundary, loading, and not-found components.
+- **`@json-render/shadcn-svelte`** -- Pre-built shadcn-svelte components for json-render Svelte apps. 36 components built on Svelte 5 + Tailwind CSS with state binding, validation, and action support. Server-safe catalog at `@json-render/shadcn-svelte/catalog`.

+
+## Usage
+
+Pick the components you need from the standard definitions:
+
+```typescript
+import { defineCatalog } from "@json-render/core";
+import { schema } from "@json-render/svelte/schema";
+import { shadcnComponentDefinitions } from "@json-render/shadcn-svelte/catalog";
+import { defineRegistry } from "@json-render/svelte";
+import { shadcnComponents } from "@json-render/shadcn-svelte";
+
+// Catalog: pick definitions
+const catalog = defineCatalog(schema, {
+  components: {
+    Card: shadcnComponentDefinitions.Card,
+    Stack: shadcnComponentDefinitions.Stack,
+    Heading: shadcnComponentDefinitions.Heading,
+    Button: shadcnComponentDefinitions.Button,
+    Input: shadcnComponentDefinitions.Input,
+  },
+  actions: {},
+});
+
+// Registry: pick matching implementations
+const { registry } = defineRegistry(catalog, {
+  components: {
+    Card: shadcnComponents.Card,
+    Stack: shadcnComponents.Stack,
+    Heading: shadcnComponents.Heading,
+    Button: shadcnComponents.Button,
+    Input: shadcnComponents.Input,
+  },
+});
+```
+
+Then render in your Svelte component:
+
+```svelte
+<script lang="ts">
+  import { Renderer, JsonUIProvider } from "@json-render/svelte";
+
+  export let spec;
+  export let registry;
+</script>
+
+<JsonUIProvider initialState={spec?.state ?? {}}>
+  <Renderer {spec} {registry} />
+</JsonUIProvider>

+
+## Notes
+
+- The `/catalog` entry point has no Svelte dependency -- use it for server-side prompt generation
+- Components use Tailwind CSS classes -- your app must have Tailwind configured
+- Component implementations use bundled shadcn-svelte primitives (not your app's `$lib/components/ui/`)
+- Form inputs support `checks` for validation (type + message pairs) and `validateOn` for timing
+- Events: inputs emit `change`/`submit`/`focus`/`blur`; buttons emit `press`; selects emit `change`/`select`

+description: Pre-built shadcn-svelte components for json-render Svelte apps. Use when working with @json-render/shadcn-svelte, adding standard UI components to a Svelte catalog, or building Svelte web UIs with shadcn-svelte + Tailwind CSS components.
+---
+
+# @json-render/shadcn-svelte
+
+Pre-built shadcn-svelte component definitions and implementations for json-render. Provides 36 components built on Svelte 5 + Tailwind CSS.
+
+## Two Entry Points
+
+| Entry Point | Exports | Use For |
+|-------------|---------|---------|
+| `@json-render/shadcn-svelte/catalog` | `shadcnComponentDefinitions` | Catalog schemas (no Svelte dependency, safe for server) |
+| `@json-render/shadcn-svelte` | `shadcnComponents`, `shadcnComponentDefinitions` | Svelte implementations + catalog schemas |
+
+## Usage Pattern
+
+Pick the components you need from the standard definitions. Do not spread all definitions -- explicitly select what your app uses:
+
+```typescript
+import { defineCatalog } from "@json-render/core";
+import { schema } from "@json-render/svelte/schema";
+import { shadcnComponentDefinitions } from "@json-render/shadcn-svelte/catalog";
+import { defineRegistry } from "@json-render/svelte";
+import { shadcnComponents } from "@json-render/shadcn-svelte";
+
+// Catalog: pick definitions
+const catalog = defineCatalog(schema, {
+  components: {
+    Card: shadcnComponentDefinitions.Card,
+    Stack: shadcnComponentDefinitions.Stack,
+    Heading: shadcnComponentDefinitions.Heading,
+    Button: shadcnComponentDefinitions.Button,
+    Input: shadcnComponentDefinitions.Input,
+  },
+  actions: {},
+});
+
+// Registry: pick matching implementations
+const { registry } = defineRegistry(catalog, {
+  components: {
+    Card: shadcnComponents.Card,
+    Stack: shadcnComponents.Stack,
+    Heading: shadcnComponents.Heading,
+    Button: shadcnComponents.Button,
+    Input: shadcnComponents.Input,
+  },
+});
+```
+
+Then render in your Svelte component:
+
+```svelte
+<script lang="ts">
+  import { Renderer, JsonUIProvider } from "@json-render/svelte";
+
+  export let spec;
+  export let registry;
+</script>
+
+<JsonUIProvider initialState={spec?.state ?? {}}>
+  <Renderer {spec} {registry} />
+</JsonUIProvider>
+```
+
+## Available Components
+
+### Layout
+- **Card** - Container with optional title, description, maxWidth, centered
+- **Stack** - Flex container with direction, gap, align, justify
+- **Grid** - Grid layout with columns (number) and gap
+- **Separator** - Visual divider with orientation
+
+### Navigation
+- **Tabs** - Tabbed navigation with tabs array, defaultValue, value
+- **Accordion** - Collapsible sections with items array and type (single/multiple)
+- **Collapsible** - Single collapsible section with title
+- **Pagination** - Page navigation with totalPages and page
+
+### Overlay
+- **Dialog** - Modal dialog with title, description, openPath
+- **Drawer** - Bottom drawer with title, description, openPath
+- **Tooltip** - Hover tooltip with content and text
+- **Popover** - Click-triggered popover with trigger and content
+- **DropdownMenu** - Dropdown with label and items array
+
+### Content
+- **Heading** - Heading text with level (h1-h4)
+- **Text** - Paragraph with variant (body, caption, muted, lead, code)
+- **Image** - Image with alt, width, height
+- **Avatar** - User avatar with src, name, size
+- **Badge** - Status badge with text and variant (default, secondary, destructive, outline)
+- **Alert** - Alert banner with title, message, type (success, warning, info, error)
+- **Carousel** - Scrollable carousel with items array
+- **Table** - Data table with columns (string[]) and rows (string[][])
+
+### Feedback
+- **Progress** - Progress bar with value, max, label
+- **Skeleton** - Loading placeholder with width, height, rounded
+- **Spinner** - Loading spinner with size and label
+
+### Input
+- **Button** - Button with label, variant (primary, secondary, danger), disabled
+- **Link** - Anchor link with label and href
+- **Input** - Text input with label, name, type, placeholder, value, checks
+- **Textarea** - Multi-line input with label, name, placeholder, rows, value, checks
+- **Select** - Dropdown select with label, name, options (string[]), value, checks
+- **Checkbox** - Checkbox with label, name, checked, checks, validateOn
+- **Radio** - Radio group with label, name, options (string[]), value, checks, validateOn
+- **Switch** - Toggle switch with label, name, checked, checks, validateOn
+- **Slider** - Range slider with label, min, max, step, value
+- **Toggle** - Toggle button with label, pressed, variant
+- **ToggleGroup** - Group of toggles with items, type, value
+- **ButtonGroup** - Button group with buttons array and selected
+
+## Validation Timing (`validateOn`)
+
+All form components support `validateOn` to control when validation runs:
+- `"change"` -- validate on every input change (default for Select, Checkbox, Radio, Switch)
+- `"blur"` -- validate when field loses focus (default for Input, Textarea)
+- `"submit"` -- validate only on form submission
+
+## Important Notes
+
+- The `/catalog` entry point has no Svelte dependency -- use it for server-side prompt generation
+- Components use Tailwind CSS classes -- your app must have Tailwind configured
+- Component implementations use bundled shadcn-svelte primitives (not your app's `$lib/components/ui/`)
+- All form inputs support `checks` for validation (type + message pairs) and `validateOn` for timing
+- Events: inputs emit `change`/`submit`/`focus`/`blur`; buttons emit `press`; selects emit `change`/`select`
