-## What It Is
+## Overview
 
-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.
+Nodarium is a **WebAssembly-based visual programming language** for creating procedural 3D plants. The app features a node-based interface where users connect WASM modules to generate plant models in real-time. Currently used to develop https://nodes.max-richter.dev, a procedural modelling tool for 3D plants.

----
+### Build Commands
-
-## 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.

-# Comprehensive UX Practices for Web Applications
-
-## Introduction
-
-This document consolidates many of the most important practical UX principles for modern web applications.
-
----
-
-# 1. Core UX Principles
-
-## 1.1 Visibility of System Status
-
-Users should always understand:
-
-- What the system is doing
-- Whether an action succeeded
-- Whether work is still in progress
-- Whether an error occurred
-
-### Good Practices
-
-- Show loading indicators immediately
-- Show success confirmations after important actions
-- Show inline validation messages
-- Display progress for long-running tasks
-- Use skeleton loading states instead of blank screens
-- Prevent silent failures
-- Avoid ambiguous UI states
-
-### Bad Practices
-
-- Buttons with no feedback after clicking
-- Infinite spinners without explanation
-- Hidden background operations
-- Saving without visible confirmation
-
----
-
-## 1.2 Predictability and Consistency
-
-Users build mental models quickly.
-
-Breaking established expectations increases cognitive load and causes mistakes.
-
-### Good Practices
-
-- Use consistent layouts
-- Keep interaction patterns stable
-- Reuse common UI conventions
-- Keep naming and terminology consistent
-- Use standard keyboard shortcuts
-- Make similar components behave similarly
-
-### Bad Practices
-
-- Different button styles for identical actions
-- Inconsistent navigation behavior
-- Custom controls that ignore platform conventions
-- Unexpected modal behavior
-
----
-
-## 1.3 Recognition Over Recall
-
-Interfaces should minimize memory requirements.
-
-Users should recognize options instead of remembering information.
-
-### Good Practices
-
-- Show recent searches
-- Use autocomplete
-- Display contextual hints
-- Preserve previously entered values
-- Use visible labels
-- Keep important actions visible
-
-### Bad Practices
-
-- Placeholder-only labels
-- Hidden functionality
-- Requiring users to remember previous state
-- Removing useful context during workflows
-
----
-
-## 1.4 Error Prevention
-
-Preventing mistakes is better than handling mistakes.
-
-### Good Practices
-
-- Disable impossible actions
-- Validate input early
-- Warn before destructive operations
-- Use constrained input formats
-- Use safe defaults
-- Prefer undo over confirmation dialogs
-
-### Bad Practices
-
-- Destructive actions near common actions
-- Easy accidental deletion
-- Poor validation timing
-- Irreversible operations without recovery
-
----
-
-# 2. Input and Form UX
-
-Forms are one of the most important and failure-prone areas in web applications.
-
----
-
-## 2.1 Input Focus Behavior
-
-### Good Practices
-
-- Autofocus the primary field when appropriate
-- Preserve focus during rerenders
-- Preserve cursor position
-- Support keyboard-first workflows
-- Use logical tab ordering
-
-### Auto-Selecting Input Text
-
-Auto-selecting text on focus is context-dependent.
-
-### Good Use Cases
-
-- Quantity fields
-- Rename dialogs
-- Editable defaults
-- Quick replacement workflows
-- Temporary values users often replace entirely
-
-### Bad Use Cases
-
-- Long textareas
-- Complex text editing
-- Fields users commonly partially edit
-- Rich text editing
-
-### Principle
-
-Only auto-select when full replacement is more likely than partial editing.
-
----
-
-## 2.2 Labels and Placeholders
-
-### Good Practices
-
-- Always use visible labels
-- Use placeholders only as supplementary examples
-- Keep labels visible after typing
-- Associate labels correctly for accessibility
-
-### Bad Practices
-
-- Placeholder-only forms
-- Ambiguous labels
-- Labels that disappear during editing
-
----
-
-## 2.3 Validation

-| Server validation   | On submit |
-
-### Good Practices
-
-- Show errors near the relevant field
-- Explain how to fix issues

-- Validate incrementally
-- Use clear language
-
-### Bad Practices
-
-- Generic “Invalid input” messages
-- Clearing form data after errors
-- Delayed validation surprises
-- Validation that interrupts typing
-
----
