+# Shared Memory Refactor Plan
+
+## Executive Summary
+
+Migrate to a single shared `WebAssembly.Memory` instance imported by all nodes using `--import-memory`. The `#[nodarium_execute]` macro writes the function's return value directly to shared memory at the specified offset.
+
+## Architecture Overview

+```
+
+## Phase 1: Compilation Configuration
+
+### 1.1 Cargo Config
+
+```toml
+# nodes/max/plantarium/box/.cargo/config.toml
+[build]
+rustflags = ["-C", "link-arg=--import-memory"]
+```
+
+Or globally in `Cargo.toml`:
+
+```toml
+[profile.release]
+rustflags = ["-C", "link-arg=--import-memory"]
+```
+
+### 1.2 Import Memory Semantics
+
+With `--import-memory`:
+
+- Nodes **import** memory from the host (not export their own)
+- All nodes receive the same `WebAssembly.Memory` instance
+- Memory is read/write accessible from all modules
+- No `memory.grow` needed (host manages allocation)
+
+## Phase 2: Macro Design
+
+### 2.1 Clean Node API
+
+```rust
+// input.json has 3 inputs: op_type, a, b
+nodarium_definition_file!("src/input.json");
+
+#[nodarium_execute]
+pub fn execute(op_type: *i32, a: *i32, b: *i32) -> Vec<i32> {
+    // Read inputs directly from shared memory
+    let op = unsafe { *op_type };
+    let a_val = f32::from_bits(unsafe { *a } as u32);
+    let b_val = f32::from_bits(unsafe { *b } as u32);
+
+    let result = match op {
+        0 => a_val + b_val,
+        1 => a_val - b_val,
+        2 => a_val * b_val,
+        3 => a_val / b_val,
+        _ => 0.0,
+    };
+
+    // Return Vec<i32>, macro handles writing to shared memory
+    vec![result.to_bits()]
+}
+```
+
+### 2.2 Macro Implementation
+
+```rust
+// packages/macros/src/lib.rs
+
+#[proc_macro_attribute]
+pub fn nodarium_execute(_attr: TokenStream, item: TokenStream) -> TokenStream {
+    let input_fn = parse_macro_input!(item as syn::ItemFn);
+    let fn_name = &input_fn.sig.ident;
+
+    // Parse definition to get input count
+    let project_dir = env::var("CARGO_MANIFEST_DIR").unwrap();
+    let def: NodeDefinition = serde_json::from_str(&fs::read_to_string(
+        Path::new(&project_dir).join("src/input.json")
+    ).unwrap()).unwrap();
+
+    let input_count = def.inputs.as_ref().map(|i| i.len()).unwrap_or(0);
+
+    // Validate signature
+    validate_signature(&input_fn, input_count);
+
+    // Generate wrapper
+    generate_execute_wrapper(input_fn, fn_name, input_count)
+}
+
+fn validate_signature(fn_sig: &syn::Signature, expected_inputs: usize) {

+
+            // Write result directly to shared memory at output_pos
+            let len_bytes = result.len() * 4;

+        }
+    };
+
+    TokenStream::from(expanded)
+}
+```
+
+### 2.3 Generated Assembly
+
+The macro generates:
+
+```asm
+; Input: output_pos in register r0, arg0 in r1, arg1 in r2, arg2 in r3
+execute:
+    ; Call user function
+    bl    user_execute           ; returns pointer to Vec<i32> in r0
+
+    ; Calculate byte length
+    ldr   r4, [r0, #8]           ; Vec::len field
+    lsl   r4, r4, #2             ; len * 4 (i32 = 4 bytes)
+
+    ; Copy Vec data to shared memory at output_pos
+    ldr   r5, [r0, #0]           ; Vec::ptr field
+    ldr   r6, [r0, #4]           ; capacity (unused)
+
+    ; memcpy(dst=output_pos, src=r5, len=r4)
+    ; (implemented via copy_from_nonoverlapping)
+
+    ; Return length
+    mov   r0, r4
+    bx    lr
+```
+
+## Phase 3: Input Reading Helpers
+
+```rust
+// packages/utils/src/accessor.rs
+
+/// Read i32 from shared memory
+#[inline]
+pub unsafe fn read_i32(ptr: *const i32) -> i32 {
+    *ptr
+}
+

+
+Step 1: Setup
+  SHARED_MEMORY = new WebAssembly.Memory({ initial: 1024 })
+  memory.offset = 0
+
+Step 2: Execute Node A (math with 3 inputs)
+  outputPos = memory.alloc(16) = 0
+  args = [0, ptr_to_op_type, ptr_to_a, ptr_to_b]
+
+  Node A reads:

+
+## Phase 8: Migration Checklist
+
+### Build Configuration
+
+- [ ] Add `--import-memory` to Rust flags in `Cargo.toml`
+- [ ] Ensure no nodes export memory
+
+### Runtime
+
+- [ ] Create `SHARED_MEMORY` instance
+- [ ] Implement `MemoryManager` with alloc/read/write
+- [ ] Create import object factory
+- [ ] Implement `SharedMemoryRuntimeExecutor`
+
+### Macro
+
+- [ ] Parse definition JSON
+- [ ] Validate function signature (N params, Vec<i32> return)
+- [ ] Generate wrapper that writes return value to `output_pos`
+- [ ] Add panic hook
+
+### Utilities
+
+- [ ] `read_i32(ptr: *const i32) -> i32`
+- [ ] `read_f32(ptr: *const i32) -> f32`
+- [ ] `read_bool(ptr: *const i32) -> bool`
+- [ ] `read_vec3(ptr: *const i32) -> [f32; 3]`
+- [ ] `read_i32_slice(ptr: *const i32, len: usize) -> &[i32]`
+
+### Nodes
+
+- [ ] `float`, `integer`, `boolean` nodes
+- [ ] `vec3` node
+- [ ] `math` node
+- [ ] `random` node
+- [ ] `box` node
+- [ ] `stem` node
+- [ ] `branch` node
+- [ ] `instance` node
+- [ ] `output` node
+
+## Phase 9: Before vs After
+
+### Before (per-node memory)
+
+```rust
+#[nodarium_execute]
+pub fn execute(input: &[i32]) -> Vec<i32> {
+    let args = split_args(input);
+    let a = evaluate_float(args[0]);
+    let b = evaluate_float(args[1]);
+    vec![(a + b).to_bits()]
+}
+```
+
+### After (shared memory)
+
+```rust
+#[nodarium_execute]
+pub fn execute(a: *const i32, b: *const i32) -> Vec<i32> {
+    use nodarium_utils::read_f32;
+    let a_val = unsafe { read_f32(a) };
+    let b_val = unsafe { read_f32(b) };
+    vec![(a_val + b_val).to_bits()]
+}
+```
+
+**Key differences:**
+
+- Parameters are input pointers, not a slice
+- Use `read_f32` helper instead of `evaluate_float`
+- Macro writes result directly to shared memory
+- All nodes share the same memory import
+
+## Phase 10: Benefits
+
+| Aspect            | Before         | After                |
+| ----------------- | -------------- | -------------------- |
+| Memory            | N × ~1MB heaps | 1 × 64-256MB shared  |
+| Cross-node access | Copy via JS    | Direct read          |
+| API               | `&[i32]` slice | `*const i32` pointer |
+| Validation        | Runtime        | Compile-time         |

+## Node System Architecture
+
+### What is a Node?
+
+Nodes are WebAssembly modules that:
+
+- Have a unique ID (e.g., `max/plantarium/stem`)
+- Define inputs with types and default values
+- Define outputs they produce
+- Execute logic when called with arguments
+
+### Node Definition Schema
+
+Nodes are defined via `definition.json` embedded in each WASM module:
+
+```json
+{
+  "id": "namespace/category/node-name",
+  "outputs": ["geometry"],
+  "inputs": {
+    "height": { "type": "float", "value": 1.0 },
+    "radius": { "type": "float", "value": 0.1 }
+  }
+}
+```
+
+For now the outputs are limited to a single output.
+
+### Node Execution
+
+Nodes receive serialized arguments and return serialized outputs. The `nodarium_utils` Rust crate provides helpers for:
+
+- Parsing input arguments
+- Creating geometry data
+- Concatenating output vectors
+
+### Node Registration
+
+Nodes are:
+
+1. Compiled to WASM files in `target/wasm32-unknown-unknown/release/`
+2. Copied to `app/static/nodes/` for serving
+3. Registered in the browser via IndexedDB using the registry package
+
+## Key Dependencies
+
+**Frontend:**
+
+- `@sveltejs/kit` - Application framework
+- `@threlte/core` & `@threlte/extras` - Three.js Svelte integration
+- `three` - 3D graphics library
+- `tailwindcss` - CSS framework
+- `comlink` - WebWorker RPC
+- `idb` - IndexedDB wrapper
+- `wabt` - WebAssembly binary toolkit
+
+**Rust/WASM:**
+
+- Language: Rust (compiled with plain cargo)
+- Output: WebAssembly (wasm32-unknown-unknown target)
+- Generic WASM wrapper for language-agnostic node development
+- `glam` - Math library (Vec2, Vec3, Mat4, etc.)
+- `nodarium_macros` - Custom procedural macros
+- `nodarium_utils` - Shared node utilities
+
+## Build Commands
+
+From root directory:
+
+```bash
+# Install dependencies
+pnpm i
+
+# Build all WASM nodes (compiles Rust, copies to app/static)
+pnpm build:nodes
+
+# Build the app (builds UI library + SvelteKit app)
+pnpm build:app
+
+# Full build (nodes + app)
+pnpm build
+
+# Development
+pnpm dev              # Run all dev commands in parallel
+pnpm dev:nodes        # Watch nodes/, auto-rebuild on changes
+pnpm dev:app_ui       # Watch app and UI package
+pnpm dev_ui           # Watch UI package only
+```
+
+## Workspace Packages
+
+The project uses pnpm workspaces with the following packages:
+
+| Package            | Location           | Purpose                        |
+| ------------------ | ------------------ | ------------------------------ |
+| @nodarium/app      | app/               | Main SvelteKit application     |
+| @nodarium/ui       | packages/ui/       | Reusable UI component library  |
+| @nodarium/registry | packages/registry/ | Node registry with persistence |
+| @nodarium/types    | packages/types/    | Shared TypeScript types        |
+| @nodarium/utils    | packages/utils/    | Shared utilities               |
+| nodarium macros    | packages/macros/   | Rust procedural macros         |
+
+## Configuration Files
+
+- `.dprint.jsonc` - Dprint formatter configuration
+- `svelte.config.js` - SvelteKit configuration (app and ui)
+- `vite.config.ts` - Vite bundler configuration
+- `tsconfig.json` - TypeScript configuration (app and packages)
+- `Cargo.toml` - Rust workspace with member packages
+- `flake.nix` - Nix development environment
+
+## Development Workflow
+
+### Adding a New Node
+
+1. Copy the `.template` directory in `nodes/max/plantarium/` to create a new node directory
+2. Define node in `src/definition.json`
+3. Implement logic in `src/lib.rs`
+4. Build with `cargo build --release --target wasm32-unknown-unknown`
+5. Test by dragging onto the node graph
+
+### Modifying UI Components
+
+1. Changes to `packages/ui/` automatically rebuild with watch mode
+2. App imports from `@nodarium/ui`
+3. Run `pnpm dev:app_ui` for hot reload
+
+## Important Notes for AI Agents
+
+1. **WASM Compilation**: Nodes require `wasm32-unknown-unknown` target (`rustup target add wasm32-unknown-unknown`)
+2. **Cross-Compilation**: WASM build happens on host, not in containers/VMs
+3. **Static Serving**: Compiled WASM files must exist in `app/static/nodes/` before dev server runs
+4. **Workspace Dependencies**: Use `workspace:*` protocol for internal packages
+5. **Threlte Version**: Uses Threlte 8.x, not 7.x (important for 3D component APIs)
+6. **Svelte 5**: Project uses Svelte 5 with runes (`$state`, `$derived`, `$effect`)
+7. **Tailwind 4**: Uses Tailwind CSS v4 with `@tailwindcss/vite` plugin
+8. **IndexedDB**: Registry uses IDB for persistent node storage in browser

+# Node Compilation and Runtime Execution
+
+## Overview
+
+Nodarium nodes are WebAssembly modules written in Rust. Each node is a compiled WASM binary that exposes a standardized C ABI interface. The system uses procedural macros to generate the necessary boilerplate for node definitions, memory management, and execution.
+
+## Node Compilation
+
+### 1. Node Definition (JSON)
+
+Each node has a `src/input.json` file that defines:
+
+```json
+{
+  "id": "max/plantarium/stem",
+  "meta": { "description": "Creates a stem" },
+  "outputs": ["path"],
+  "inputs": {
+    "origin": { "type": "vec3", "value": [0, 0, 0], "external": true },
+    "amount": { "type": "integer", "value": 1, "min": 1, "max": 64 },
+    "length": { "type": "float", "value": 5 },
+    "thickness": { "type": "float", "value": 0.2 }
+  }
+}
+```
+
+### 2. Procedural Macros
+
+The `nodarium_macros` crate provides two procedural macros:
+
+#### `#[nodarium_execute]`
+
+Transforms a Rust function into a WASM-compatible entry point:
+
+```rust
+#[nodarium_execute]
+pub fn execute(input: &[i32]) -> Vec<i32> {
+    // Node logic here
+}
+```
+
+The macro generates:
+- **C ABI wrapper**: Converts the WASM interface to a standard C FFI
+- **`execute` function**: Takes `(ptr: *const i32, len: usize)` and returns `*mut i32`
+- **Memory allocation**: `__alloc(len: usize) -> *mut i32` for buffer allocation
+- **Memory deallocation**: `__free(ptr: *mut i32, len: usize)` for cleanup
+- **Static output buffer**: `OUTPUT_BUFFER` for returning results
+- **Panic hook**: Routes panics through `host_log_panic` for debugging
+- **Internal logic wrapper**: Wraps the original function
+
+#### `nodarium_definition_file!("path")`
+
+Embeds the node definition JSON into the WASM binary:
+
+```rust
+nodarium_definition_file!("src/input.json");
+```
+
+Generates:
+- **`DEFINITION_DATA`**: Static byte array in `nodarium_definition` section
+- **`get_definition_ptr()`**: Returns pointer to definition data
+- **`get_definition_len()`**: Returns length of definition data
+
+### 3. Build Process
+
+Nodes are compiled with:
+```bash
+cargo build --release --target wasm32-unknown-unknown
+```
+
+The resulting `.wasm` files are copied to `app/static/nodes/` for serving.
+

+└─────────────────────────────────────────────────────────────┘
+```
+
+### 1. MemoryRuntimeExecutor
+
+The core execution engine in `runtime-executor.ts`:
+
+#### Metadata Collection (`addMetaData`)
+
+1. Load node definitions from registry
+2. Build parent/child relationships from graph edges
+3. Calculate execution depth via reverse BFS from output node
+
+#### Node Sorting
+
+Nodes are sorted by depth (highest depth first) for bottom-up execution:
+
+```
+Depth 3:  n3  n6
+Depth 2:  n2  n4  n5
+Depth 1:  n1
+Depth 0:  Output
+Execution order: n3, n6, n2, n4, n5, n1, Output
+```
+
+#### Input Collection
+
+For each node, inputs are gathered from:
+1. **Connected nodes**: Results from parent nodes in the graph
+2. **Node props**: Values stored directly on the node instance
+3. **Settings**: Global settings mapped via `setting` property
+4. **Defaults**: Values from node definition
+
+#### Input Encoding
+
+Values are encoded as `Int32Array`:
+- **Floats**: IEEE 754 bits cast to i32
+- **Vectors**: `[0, count, v1, v2, v3, 1, 1]` (nested bracket format)
+- **Booleans**: `0` or `1`
+- **Integers**: Direct i32 value
+
+#### Caching
+
+Results are cached using:
+```typescript
+inputHash = `node-${node.id}-${fastHashArrayBuffer(encoded_inputs)}`
+```
+
+The cache uses LRU eviction (default size: 50 entries).
+
+### 2. Execution Flow
+
+```typescript
+async execute(graph: Graph, settings) {
+  // 1. Load definitions and build node relationships
+  const [outputNode, nodes] = await this.addMetaData(graph);
+
+  // 2. Sort nodes by depth (bottom-up)
+  const sortedNodes = nodes.sort((a, b) => b.depth - a.depth);
+
+  // 3. Execute each node
+  for (const node of sortedNodes) {
+    const inputs = this.collectInputs(node, settings);
+    const encoded = concatEncodedArrays(inputs);
+    const result = nodeType.execute(encoded);
+    this.results[node.id] = result;
+  }
+
+  // 4. Return output node result
+  return this.results[outputNode.id];
+}
+```
+
+### 3. Worker Isolation
+
+`WorkerRuntimeExecutor` runs execution in a WebWorker via Comlink:
+
+```typescript
+class WorkerRuntimeExecutor implements RuntimeExecutor {
+  private worker = new ComlinkWorker(...);
+
+  async execute(graph, settings) {
+    return this.worker.executeGraph(graph, settings);
+  }
+}
+```
+
+The worker backend (`worker-runtime-executor-backend.ts`):
+- Creates a single `MemoryRuntimeExecutor` instance
+- Manages caching state
+- Collects performance metrics
+
+### 4. Remote Execution (Optional)
+
+`RemoteRuntimeExecutor` can execute graphs on a remote server:
+
+```typescript
+class RemoteRuntimeExecutor implements RuntimeExecutor {
+  async execute(graph, settings) {
+    const res = await fetch(this.url, {
+      method: "POST",
+      body: JSON.stringify({ graph, settings })
+    });
+    return new Int32Array(await res.arrayBuffer());
+  }
+}
+```
+
+## Data Encoding Format
+
+### Bracket Notation
+
+Inputs and outputs use a nested bracket encoding:
+
+```
+[0, count, item1, item2, ..., 1, 1]
+   ^    ^       items                ^  ^
+   |    |                         |  |
+   |    |                         |  +-- closing bracket
+   |    +-- number of items + 1   |
+   +-- opening bracket (0)         +-- closing bracket (1)
+```
+
+### Example Encodings
+
+**Float (5.0)**:
+```typescript
+encodeFloat(5.0) // → 1084227584 (IEEE 754 bits as i32)
+```
+
+**Vec3 ([1, 2, 3])**:
+```typescript
+[0, 4, encodeFloat(1), encodeFloat(2), encodeFloat(3), 1, 1]
+```
+
+**Nested Math Expression**:
+```
+[0, 3, 0, 2, 0, 3, 0, 0, 0, 3, 7549747, 127, 1, 1, ...]
+```
+
+### Decoding Utilities
+
+From `packages/utils/src/tree.rs`:
+- `split_args()`: Parses nested bracket arrays into segments
+- `evaluate_float()`: Recursively evaluates and decodes float expressions
+- `evaluate_int()`: Evaluates integer/math node expressions
+- `evaluate_vec3()`: Decodes vec3 arrays
+
+## Geometry Data Format
+
+### Path Data
+
+Paths represent procedural plant structures:
+
+```
+[0, count, [0, header_size, node_type, depth, x, y, z, w, ...], 1, 1]
+```
+
+Each point has 4 values: x, y, z position + thickness (w).
+
+### Geometry Data
+
+Meshes use a similar format with vertices and face indices.
+
+## Performance Tracking
+
+The runtime collects detailed performance metrics:
+- `collect-metadata`: Time to build node graph
+- `collected-inputs`: Time to gather inputs
+- `encoded-inputs`: Time to encode inputs
+- `hash-inputs`: Time to compute cache hash
+- `cache-hit`: 1 if cache hit, 0 if miss
+- `node/{node_type}`: Time per node execution
+
+## Caching Strategy
+
+### MemoryRuntimeCache
+
+LRU cache implementation:
+```typescript
+class MemoryRuntimeCache {
+  private map = new Map<string, unknown>();
+  size: number = 50;
+
+  get(key) { /* move to front */ }
+  set(key, value) { /* evict oldest if at capacity */ }
+}
+```
+
+### IndexDBCache
+
+For persistence across sessions, the registry uses IndexedDB caching.
+
+## Summary
+
+The Nodarium node system works as follows:
+
+1. **Compilation**: Rust functions are decorated with macros that generate C ABI WASM exports
+2. **Registration**: Node definitions are embedded in WASM and loaded at runtime
+3. **Graph Analysis**: Runtime builds node relationships and execution order
+4. **Bottom-Up Execution**: Nodes execute from leaves to output
+5. **Caching**: Results are cached per-node-inputs hash for performance
+6. **Isolation**: Execution runs in a WebWorker to prevent main thread blocking

-## What It Is
-
-Nodarium is a **node-based visual programming editor**. Users wire together nodes on a 2D canvas; each node is a WebAssembly module that receives typed inputs and produces typed outputs. A live Three.js viewer renders the resulting 3D geometry/paths/instances.

-## Key Types
-
-```typescript
-// packages/types/src/types.ts
-
-type NodeId = `${string}/${string}/${string}`; // e.g. "max/plantarium/stem"
-
-type NodeInstance = {
-  id: number;
-  type: NodeId;
-  position: [number, number];
-  props?: Record<string, number | number[]>; // current parameter values
-  meta?: { title?: string; lastModified?: string };
-  state: NodeRuntimeState; // runtime-only, NOT serialized
-};
-
-type NodeRuntimeState = {
-  type?: NodeDefinition; // resolved definition
-  parents?: NodeInstance[];
-  children?: NodeInstance[];
-  x?: number;
-  y?: number; // interpolated position
-  mesh?: Mesh; // Three.js mesh reference
-  ref?: HTMLElement;
-};
-
-type NodeDefinition = {
-  id: NodeId;
-  inputs?: Record<string, NodeInput>;
-  outputs?: string[]; // output type names
-  meta?: { title?: string; description?: string };
-  execute(input: Int32Array): Int32Array; // WASM function
-};
-
-// Edge: [fromNode, outputIndex, toNode, inputSocketName]
-type Edge = [NodeInstance, number, NodeInstance, string];
-
-type Graph = {
-  nodes: NodeInstance[];
-  edges: [number, number, number, string][]; // serialized (IDs, not refs)

-};
-
-type GroupDefinition = {
-  id: number;
-  nodes: NodeInstance[];
-  edges: Edge[];
-  inputs?: Record<string, NodeInput>;
-  outputs?: string[];
-};
-```
-
-### NodeInput socket types
-
-`float` | `integer` | `boolean` | `select` | `seed` | `vec3` | `geometry` | `path` | `shape` | `color` | `*` (wildcard)
-
-Each input can have: `value` (default), `label`, `hidden`, `external`, `setting` (link to graph setting), `accepts` (extra compatible types).
-
----
-
-## Patterns & Conventions
-
-### Svelte 5 reactivity
-
-The codebase uses Svelte 5 runes throughout — `$state`, `$derived`, `$effect`. Collections use `SvelteMap<K,V>` and `SvelteSet<T>` (from `svelte/reactivity`) instead of plain Map/Set so that mutations trigger reactive updates.
-
-### Context API
-
-`GraphManager` and `GraphState` are provided via Svelte context (`setContext` / `getContext`) inside `GraphInterface`. All child components (Node, Edge, etc.) consume them via context rather than props.
-
-### Edge representation
-
-In memory, edges are `[NodeInstance, outputIndex, NodeInstance, inputSocketName]` — direct object references for fast traversal. On serialization (`Graph.edges`), they become `[nodeId, outputIndex, nodeId, inputSocketName]` (plain IDs).
-
-### Socket compatibility
-
-```typescript
-areSocketsCompatible(outputType: string, inputType: string | string[]): boolean
-// '*' wildcard matches any type; 'geometry' accepts ['geometry', 'instances']
-```
-
-### WASM execution interface
-
-Every node exposes a single function: `execute(input: Int32Array): Int32Array`.
-Data encoding (Plantarium):
-
-- `[0, stemDepth, ...x,y,z,thickness]` — path
-- `[1, vertexCount, faceCount, ...faces, ...vertices, ...normals]` — geometry
-- `[2, vertexCount, faceCount, instanceCount, stemDepth, ...]` — instances
-
-### Event emitter
-
-`GraphManager extends EventEmitter<{ save, result, settings }>`. Subscribe with `manager.on('result', cb)`. Used to decouple the editor UI from runtime execution and persistence.
-
-### History
-
-Every mutation goes through `HistoryManager`. Call `this.history.save(this.serialize())` before mutations; undo/redo replays jsondiffpatch deltas.
-
-### Internal node IDs
-
-Built-in nodes use the `__internal/` namespace: `__internal/group/instance`, `__internal/node/debug`. Virtual boundary nodes use `__virtual/`: `__virtual/group/input`, `__virtual/group/output`.
-
----
-
-## In-Progress: Node Groups (`feat/group-node-own`)
-
-Group selected nodes with **Ctrl+G**. A `GroupDefinition` is stored in `Graph.groups[]`; a group instance node (`__internal/group/instance`) referencing it by `props.groupId` replaces the selected nodes.

-# Svelte library
-
-Everything you need to build a Svelte library, powered by [`sv`](https://npmjs.com/package/sv).
-
-Read more about creating a library [in the docs](https://svelte.dev/docs/kit/packaging).
-
-## Creating a project
-
-If you're seeing this, you've probably already done this step. Congrats!
-
-```sh
-# create a new project in the current directory
-npx sv create
-
-# create a new project in my-app
-npx sv create my-app
-```
-
-To recreate this project with the same configuration:
-
-```sh
-# recreate this project
-pnpm dlx sv@0.15.1 create --template library --types ts --add prettier eslint tailwindcss="plugins:none" --install pnpm planty
-```
-
-## Developing
-
-Once you've created a project and installed dependencies with `npm install` (or `pnpm install` or `yarn`), start a development server:
-
-```sh
-npm run dev
-
-# or start the server and open the app in a new browser tab
-npm run dev -- --open
-```
-
-Everything inside `src/lib` is part of your library, everything inside `src/routes` can be used as a showcase or preview app.
-
-## Building
-
-To build your library:
-
-```sh
-npm pack
-```
-
-To create a production version of your showcase app:
-
-```sh
-npm run build
-```
-
-You can preview the production build with `npm run preview`.
-
-> To deploy your app, you may need to install an [adapter](https://svelte.dev/docs/kit/adapters) for your target environment.
-
-## Publishing
-
-Go into the `package.json` and give your package the desired name through the `"name"` option. Also consider adding a `"license"` field and point it to a `LICENSE` file which you can create from a template (one popular option is the [MIT license](https://opensource.org/license/mit/)).
-
-To publish your library to [npm](https://www.npmjs.com):
-
-```sh
-npm publish
-```
