+## Model Types Overview
+
+The project provides three main types of model instantiation:
+
+| Type        | Component                                                | Use Case                                     |
+| ----------- | -------------------------------------------------------- | -------------------------------------------- |
+| Static      | `SimpleModel`                                            | Props, decoration, objects without animation |
+| Animated    | `AnimatedModel`                                          | Characters, animated objects with skeleton   |
+| Interactive | `GrabbableObject`, `TriggerObject`, `InteractableObject` | Objects player can interact with             |
+
+---
+
+## SimpleModel - Static Models
+
+Use for GLTF models **without** skeleton/armature and no animations.
+
+```tsx
+import { SimpleModel } from "@/components/3d";
+
+<SimpleModel
+  modelPath="/models/elecsimple/model.gltf"
+  position={[0, 0, -5]}
+  rotation={[0, 45, 0]}
+  scale={1}
+  castShadow={true}
+  receiveShadow={true}
+/>;
+```
+
+### Props
+
+| Prop            | Type                     | Default     | Description                       |
+| --------------- | ------------------------ | ----------- | --------------------------------- |
+| `modelPath`     | `string`                 | required    | Path to GLTF file in `/public`    |
+| `position`      | `Vector3Tuple`           | `[0, 0, 0]` | World position [x, y, z]          |
+| `rotation`      | `Vector3Tuple`           | `[0, 0, 0]` | Rotation in degrees [x, y, z]     |
+| `scale`         | `number \| Vector3Tuple` | `1`         | Scale factor or [x, y, z]         |
+| `castShadow`    | `boolean`                | `true`      | Enable shadow casting             |
+| `receiveShadow` | `boolean`                | `true`      | Enable shadow receiving           |
+| `children`      | `ReactNode`              | -           | Child components to render inside |
+
+---
+
+## AnimatedModel - Animated Models
+
+Use for GLTF models **with** skeleton/armature and animations (like Mixamo characters).
+
+```tsx
+import { AnimatedModel, useAnimatedModel } from "@/components/3d";
+
+// Basic usage
+<AnimatedModel
+  modelPath="/models/elec/model.gltf"
+  defaultAnimation="Idle"
+  position={[0, 0, -5]}
+  rotation={[0, 0, 0]}
+  scale={0.01}
+  autoPlay={true}
+  speed={1}
+  fadeDuration={0.3}
+/>;
+```
+
+### Props
+
+| Prop               | Type                     | Default     | Description                                   |
+| ------------------ | ------------------------ | ----------- | --------------------------------------------- |
+| `modelPath`        | `string`                 | required    | Path to GLTF file in `/public`                |
+| `defaultAnimation` | `string`                 | `"Idle"`    | Animation name to play by default             |
+| `animations`       | `string[]`               | `[]`        | List of animation names (optional)            |
+| `position`         | `Vector3Tuple`           | `[0, 0, 0]` | World position [x, y, z]                      |
+| `rotation`         | `Vector3Tuple`           | `[0, 0, 0]` | Rotation in degrees [x, y, z]                 |
+| `scale`            | `number \| Vector3Tuple` | `1`         | Scale factor                                  |
+| `autoPlay`         | `boolean`                | `true`      | Auto-play default animation                   |
+| `speed`            | `number`                 | `1`         | Animation playback speed                      |
+| `fadeDuration`     | `number`                 | `0.3`       | Transition duration in seconds                |
+| `onLoaded`         | `() => void`             | -           | Callback when model loads                     |
+| `onAnimationEnd`   | `(name: string) => void` | -           | Callback when animation ends                  |
+| `children`         | `ReactNode`              | -           | Child components (can use `useAnimatedModel`) |
+
+### Important: Scale
+
+Animated models (like Mixamo exports) often need a small scale (e.g., `0.01`) because they are exported in meters while Three.js uses different units. Adjust until the model appears at the right size.
+
+---
+
+## Animation Control
+
+To control animations from inside or outside the `AnimatedModel`, use the `useAnimatedModel` hook.
+
+### Basic Control
+
+```tsx
+import { AnimatedModel, useAnimatedModel } from "@/components/3d";
+
+// Create a controller component to use inside AnimatedModel
+function AnimationController() {
+  const { play, stop, fadeTo, currentAnimation, names, setSpeed, isReady } =
+    useAnimatedModel();
+
+  // names contains all available animation names
+  // currentAnimation is the name of the currently playing animation
+  // isReady is true when model and animations are loaded
+
+  return (
+    <mesh onClick={() => play("Run", 0.5)}>
+      <boxGeometry />
+    </mesh>
+  );
+}
+
+// Usage
+<AnimatedModel
+  modelPath="/models/elec/model.gltf"
+  defaultAnimation="Idle"
+  position={[0, 0, -5]}
+  scale={0.01}
+>
+  <AnimationController />
+</AnimatedModel>;
+```
+
+### Available Methods
+
+| Method             | Signature                               | Description                          |
+| ------------------ | --------------------------------------- | ------------------------------------ |
+| `play`             | `(name: string, fade?: number) => void` | Play animation with optional fade    |
+| `fadeTo`           | `(name: string, fade?: number) => void` | Fade to another animation            |
+| `stop`             | `(fade?: number) => void`               | Stop and return to default animation |
+| `setSpeed`         | `(speed: number) => void`               | Set animation speed                  |
+| `currentAnimation` | `string`                                | Current animation name (getter)      |
+| `names`            | `string[]`                              | Available animation names            |
+| `isReady`          | `boolean`                               | Whether model is loaded              |
+
+### Transition Example
+
+```tsx
+function Character() {
+  const { play, fadeTo, currentAnimation } = useAnimatedModel();
+
+  const handleWalk = () => fadeTo("Walk", 0.5); // 0.5s fade
+  const handleRun = () => play("Run", 0.3); // 0.3s fade
+  const handleIdle = () => play("Idle", 0.5); // return to idle
+
+  return (
+    <group>
+      <mesh onClick={handleWalk} position={[-1, 0, 0]}>
+        <boxGeometry />
+      </mesh>
+      <mesh onClick={handleRun} position={[0, 0, 0]}>
+        <boxGeometry />
+      </mesh>
+      <mesh onClick={handleIdle} position={[1, 0, 0]}>
+        <boxGeometry />
+      </mesh>
+    </group>
+  );
+}
+```
+
+### Combined: GrabbableObject with Animation
+
+You can combine `AnimatedModel` inside `GrabbableObject` to create animated objects that can be picked up:
+
+```tsx
+import { AnimatedModel, GrabbableObject } from "@/components/3d";
+
+// Animated weapon/tool that player can pick up
+<GrabbableObject position={[0, 1, 0]} colliders="cuboid">
+  <AnimatedModel
+    modelPath="/models/sword/model.gltf"
+    defaultAnimation="Idle"
+    position={[0, 0, 0]}
+    scale={0.02}
+    autoPlay={true}
+  />
+</GrabbableObject>;
+```
+
+Or create an animated character that can be grabbed:
+
+```tsx
+import {
+  AnimatedModel,
+  GrabbableObject,
+  useAnimatedModel,
+} from "@/components/3d";
+
+// Controller that triggers animations when grabbed
+function AnimatedGrabber() {
+  const { play, fadeTo } = useAnimatedModel();
+
+  return (
+    <AnimatedModel
+      modelPath="/models/elec/model.gltf"
+      defaultAnimation="Idle"
+      position={[0, 0, 0]}
+      scale={0.01}
+      autoPlay={true}
+    />
+  );
+}
+
+// When grabbed, play "Grab" animation
+<GrabbableObject
+  position={[0, 1, 0]}
+  colliders="cuboid"
+  onGrab={() => {
+    // This would require a context or store to trigger
+    console.log("Object grabbed!");
+  }}
+>
+  <AnimatedGrabber />
+</GrabbableObject>;
+```
+
+**Note:** For complex interactions (like playing specific animations when grabbing), you'll need to connect the grab events to animation controls via a state manager or context.
+
+---
+
+## Other 3D Components
+
+### GrabbableObject
+
+Objects that can be picked up by the player.
+
+```tsx
+import { GrabbableObject } from "@/components/3d";
+
+<GrabbableObject position={[0, 1, 0]} colliders="cuboid">
+  <mesh>
+    <boxGeometry args={[0.5, 0.5, 0.5]} />
+    <meshStandardMaterial color="red" />
+  </mesh>
+</GrabbableObject>;
+```
+
+### TriggerObject
+
+Objects that trigger events when interacted with.
+
+```tsx
+import { TriggerObject } from "@/components/3d";
+
+<TriggerObject
+  position={[0, 1, 0]}
+  soundPath="/sounds/click.mp3"
+  onTrigger={() => console.log("Triggered!")}
+>
+  <mesh>
+    <sphereGeometry />
+    <meshStandardMaterial color="blue" />
+  </mesh>
+</TriggerObject>;
+```
+
+### InteractableObject
+
+Base object for interactions.
+
+```tsx
+import { InteractableObject } from "@/components/3d";
+
+<InteractableObject
+  position={[0, 1, 0]}
+  onInteract={() => console.log("Interacted!")}
+>
+  <mesh>
+    <cylinderGeometry />
+    <meshStandardMaterial color="green" />
+  </mesh>
+</InteractableObject>;
+```

+
+## Technical Notes
+
+### GLTF Models
+
+- Models should be placed in `/public/models/`
+- Supported formats: `.gltf`, `.glb`
+- Animated models must have an Armature/skeleton for animations to work
+
+### Model Scale Issue
+
+If animated models don't appear, they may be too small or too large. Try:
+
+- Scale `0.01` for Mixamo-exported models
+- Scale `1` for models in correct units
+
+### Cloning
+
+- `SimpleModel` uses `scene.clone()` for proper React lifecycle
+- `AnimatedModel` uses the original scene directly to preserve SkinnedMesh + Armature structure
+
+### Animation System
+
+The animation system uses:
+
+- `@react-three/drei`: `useGLTF` for loading, `useAnimations` for animation control
+- Three.js: `AnimationMixer` for playback
+
+### No State Machine
+
+This system intentionally avoids complex state machines (like Unity's Animator). For simple animation transitions, use the `play`, `fadeTo`, and `stop` methods directly.

+# Editor Technical Notes
+
+This document describes the map editor that exists in the current codebase.
+
+## Purpose
+
+The editor is a React route used to inspect and adjust the `public/map.json` scene data from inside the La-Fabrik app. It shares the same `MapNode` data format as the game scene and uses React Three Fiber for rendering.
+
+## Routing
+
+- `/` renders the playable La-Fabrik scene.
+- `/editor` renders the map editor.
+- `src/App.tsx` mounts TanStack Router through `RouterProvider`.
+- `src/router.tsx` defines the `/editor` route and imports `EditorPage` from `src/pages/editor/page.tsx`.
+
+## File Structure
+
+```txt
+src/
+├── pages/
+│   └── editor/
+│       └── page.tsx

+└── utils/
+    ├── editor/
+    │   └── loadEditorScene.ts
+    └── loadMapSceneData.ts
+```
+
+## Responsibilities
+
+`src/pages/editor/page.tsx` is the route-level composition component. It owns route-specific state such as selected object, hovered object, transform mode, and player-mode toggle.
+
+`src/hooks/editor/useEditorSceneData.ts` loads the default map data and handles folder uploads.
+
+`src/hooks/editor/useEditorHistory.ts` owns editor undo and redo history.
+
+`src/components/editor/scene/EditorScene.tsx` composes the editor canvas scene, camera controls, lights, keyboard shortcuts, and `EditorMap`.
+
+`src/components/editor/scene/EditorMap.tsx` renders map nodes, fallback cubes, selection highlighting, and transform controls.
+
+`src/components/editor/EditorControls.tsx` renders the HTML control panel outside the canvas.
+
+`src/controls/editor/FlyController.tsx` provides editor movement controls for player-style navigation.
+
+`src/utils/loadMapSceneData.ts` is shared by the game map and editor. It loads `/map.json` and resolves available `public/models/{name}/model.gltf` files.
+
+`src/utils/editor/loadEditorScene.ts` contains editor-only upload handling for user-selected folders.
+
+## Data Format
+
+The shared editor type lives in `src/types/editor.ts`.
+
+```ts
+interface MapNode {
+  name: string;
+  type: string;
+  position: [number, number, number];
+  rotation: [number, number, number];
+  scale: [number, number, number];
+}
+```
+
+`public/map.json` is expected to be a `MapNode[]`.
+
+```json
+[
+  {
+    "name": "pylone",
+    "type": "Mesh",
+    "position": [0, 5, 0],
+    "rotation": [0, 1.57, 0],
+    "scale": [1, 1, 1]
+  }
+]
+```
+
+Each node `name` maps to a model folder:
+
+```txt
+public/
+├── map.json
+└── models/
+    └── pylone/
+        └── model.gltf
+```
+
+If a model is missing, the editor renders a fallback cube so the node can still be selected and transformed.
+
+## Editor Flow
+
+1. `EditorPage` mounts on `/editor`.
+2. `useEditorSceneData` calls `loadMapSceneData()`.
+3. `loadMapSceneData()` loads `/map.json` and available model URLs.
+4. If `/map.json` is missing, the page displays a folder-upload flow.
+5. `EditorScene` renders the grid, lights, camera controls, and map nodes.
+6. `EditorControls` exposes transform mode, history actions, export, save, and selection info.
+
+## Controls
+
+- Click: select a node.
+- `Esc`: clear selection.
+- `T`: translate mode.
+- `R`: rotate mode.
+- `S`: scale mode.
+- `Ctrl+Z` or `Cmd+Z`: undo.
+- `Ctrl+Y` or `Cmd+Y`: redo.
+- `WASD`, `ZQSD`, or arrow keys: move in player-controller mode.
+- `Space`: move upward in player-controller mode.
+- `Shift`: move downward in player-controller mode.
+
+## Saving And Exporting
+
+The editor supports two output paths:
+
+- Export JSON downloads the current `MapNode[]` as `map.json`.
+- Save to Server posts the current `MapNode[]` to `/api/save-map`.
+
+The dev-only `/api/save-map` endpoint is implemented by the Vite plugin in `vite.config.ts`. It writes to `public/map.json` and enforces a maximum payload size.
+
+## Styling
+
+Editor styles are in `src/index.css` under the `/* Editor page */` section. Classes are prefixed with `editor-` to avoid collisions with the game UI.
+
+## Known Limitations
+
+- Uploaded model object URLs are not currently revoked after replacement or unmount.
+- Large `map.json` files are not virtualized, culled, or LOD-managed.
+- There is no snap-to-grid, duplication, material editing, or object creation workflow.
+- Save to Server is a Vite dev-server helper, not a production backend API.

+# Editor User Guide
+
+The map editor is available at `/editor`. It is a browser-based tool for inspecting and adjusting the objects listed in `public/map.json`.
+
+## Purpose
+
+Use the editor when you need to move, rotate, or scale existing map objects without editing JSON by hand.
+
+The editor reads the same map data as the runtime scene:
+
+- `public/map.json` contains the object list.
+- `public/models/{name}/model.gltf` contains the matching 3D model for each object name.
+- Missing models are displayed as gray fallback cubes, so incomplete maps remain editable.
+
+## Map Node Format
+
+Each entry in `public/map.json` represents one object:
+
+| Field      | Description                                       |
+| ---------- | ------------------------------------------------- |
+| `name`     | Model folder name in `public/models/{name}`       |
+| `type`     | Object category                                   |
+| `position` | Object position as `[x, y, z]`                    |
+| `rotation` | Object rotation as `[x, y, z]`, expressed radians |
+| `scale`    | Object scale as `[x, y, z]`                       |
+
+## Editing Workflow
+
+1. Open `/editor` in the local app.
+2. Click an object in the scene to select it.
+3. Choose a transform mode: translate, rotate, or scale.
+4. Drag the transform gizmo in the 3D view.
+5. Check the JSON inspector if you need exact values.
+6. Use undo or redo if the transform is not correct.
+7. Export the JSON or save it to the dev server.
+
+## Controls
+
+| Action               | Input                      |
+| -------------------- | -------------------------- |
+| Select object        | Click object               |
+| Deselect             | `Esc` or click empty space |
+| Translate mode       | `T`                        |
+| Rotate mode          | `R`                        |
+| Scale mode           | `S`                        |
+| Undo                 | `Ctrl+Z`                   |
+| Redo                 | `Ctrl+Y`                   |
+| Locked view movement | `WASD`, `ZQSD`, arrows     |
+| Move up              | `Space`                    |
+| Move down            | `Shift`                    |
+
+## View Mode
+
+The `Lock view` action switches the editor into a movement mode closer to the runtime player camera. Use it to navigate larger scenes while keeping the transform tools available.
+
+## JSON Inspector
+
+The side panel includes a raw JSON inspector:
+
+- When no object is selected, it shows the full map node list.
+- When an object is selected, it highlights the JSON lines for that object.
+
+This is useful for checking numeric transform values before saving or exporting.
+
+## Saving Changes
+
+### Export JSON
+
+`Export JSON` downloads the current map node list as `map.json`. Use this when you want to manually replace `public/map.json`.
+
+### Save To Server
+
+`Save to server` is available only during local development. It writes the edited map back to `public/map.json` through the Vite dev-server endpoint.
+
+The button is hidden in production builds because production persistence is not implemented.
+
+## Current Limitations
+
+- The editor only modifies existing nodes.
+- It does not create or delete objects.
+- It does not edit model files or textures.
+- It does not provide production persistence.
+- Fallback cubes indicate missing models; they are editor placeholders, not exported assets.

+
+## Structure runtime
+
+- \`src/App.tsx\` monte le \`RouterProvider\`, qui pilote l'affichage des vues de l'application.
+- \`src/pages/page.tsx\` monte le \`Canvas\`, le \`World\` 3D, l'overlay de performance debug et les overlays HTML.
+- \`src/world/World.tsx\` compose la scène active avec :
+  - l'environnement et l'éclairage
+  - les helpers debug et le mode caméra debug
+  - soit la carte principale, soit la scène de test physique debug
+  - le rig joueur quand le mode caméra actif est \`player\`
+- \`src/world/GameMap.tsx\` charge les modèles de carte disponibles et construit l'octree de collision.
+- \`src/world/debug/TestScene.tsx\` fournit une scène orientée debug pour les interactions et la physique.
+- \`src/world/player/Player.tsx\` monte la caméra et le contrôleur.
+- \`src/world/player/PlayerController.tsx\` gère le mouvement pointer lock, le saut et les inputs d'interaction.
+
+## Modèle d'interaction
+
+- \`src/managers/InteractionManager.ts\` est la source d'état actuelle des interactions.
+- \`src/components/three/InteractableObject.tsx\` gère la détection de focus par distance et raycasting.
+- \`src/components/three/TriggerObject.tsx\` implémente les interactions de type trigger.
+- \`src/components/three/GrabbableObject.tsx\` implémente les interactions saisir / relâcher.
+- \`src/hooks/useInteraction.ts\` expose un snapshot d'interaction à l'UI React.
+- \`src/components/ui/InteractPrompt.tsx\` affiche le prompt \`E\` pour les interactions trigger.
+
+## Audio
+
+- \`src/managers/AudioManager.ts\` fournit actuellement une lecture de sons one-shot avec pool.
+- Les interactions trigger peuvent lancer directement un son via \`AudioManager\`.
+
+## Système debug
+
+- Le mode debug est activé avec \`?debug\`.
+- \`src/utils/debug/Debug.ts\` possède l'instance \`lil-gui\` et les contrôles debug.
+- \`src/hooks/debug/useCameraMode.ts\` et \`src/hooks/debug/useSceneMode.ts\` s'abonnent à l'état debug.
+- \`src/components/debug/DebugPerf.tsx\` monte \`r3f-perf\` en lazy uniquement en mode debug.
+- \`src/components/debug/scene/DebugHelpers.tsx\` monte les helpers debug.
+- \`src/components/debug/scene/DebugCameraControls.tsx\` monte la caméra libre debug.
+
+## Limites actuelles
+
+- Le dépôt est encore un prototype, pas le runtime complet du jeu.
+- \`src/world/debug/TestScene.tsx\` fait encore partie de la composition active.
+- Il n'existe pas encore d'orchestrateur gameplay central comme \`GameManager\`.
+- Les systèmes de missions, zones, cinématiques et dialogues ne sont pas implémentés.
+- Le joueur utilise une collision octree et des règles simples, pas une pile physique gameplay complète.
+`;
+
+export const targetArchitectureFr = `# Architecture cible
+
+Ce document décrit l'architecture visée à moyen terme pour le projet.
+
+## Relation avec le code actuel
+
+- \`docs/technical/architecture.md\` reste la source de vérité de ce qui existe maintenant.
+- Ce document est volontairement aspirational.
+- Si ce document contredit l'implémentation actuelle, l'implémentation actuelle gagne.
+
+## Objectifs
+
+- Garder \`App.tsx\` petit et centré sur l'orchestration.
+- Séparer le code de production du monde des chemins runtime uniquement debug.
+- Garder une source de vérité claire par responsabilité.
+- Faire grandir les systèmes gameplay progressivement, sans préconstruire une architecture vide.
+
+## Couches prévues
+
+### Couche App
+
+- \`App.tsx\` monte la scène canvas et les overlays HTML de premier niveau.
+- Il doit rester fin et éviter la logique gameplay.
+
+### Couche World
+
+- \`src/world/\` doit contenir la composition de scène de production et les objets de scène de production.
+- Responsabilités attendues :
+  - composition du monde
+  - carte, environnement, éclairage
+  - contrôleur joueur
+  - ancres d'interaction de production
+  - post-processing de production si nécessaire
+
+### Couche Debug
+
+- Les scènes et outils uniquement debug doivent être isolés du chemin de production.
+- Responsabilités attendues :
+  - \`lil-gui\`
+  - overlay de performance
+  - helpers de scène
+  - caméra libre et contrôles de calibration
+  - scènes temporaires de test utilisées pendant le développement
+
+### Couche UI
+
+- \`src/components/ui/\` doit contenir les overlays HTML visibles par le joueur.
+- Exemples futurs :
+  - crosshair
+  - flow de chargement
+  - HUD de mission
+  - overlays narratifs
+
+### Couche Gameplay
+
+- À mesure que le projet grandit, l'état gameplay peut évoluer vers une couche d'orchestration plus claire.
+- Sujets probables :
+  - missions
+  - zones
+  - cinématiques
+  - dialogues
+  - audio
+  - interactions
+
+## Règles
+
+- Préférer du code direct et fonctionnel plutôt qu'un échafaudage spéculatif.
+- Les types partagés doivent rester proches de leur domaine jusqu'à avoir plusieurs vrais consommateurs.
+- Éviter de créer de nouveaux managers ou services sans besoin runtime actif.
+- Les chemins runtime uniquement debug doivent être clairement marqués et faciles à retirer plus tard.
+`;
+
+export const featuresFr = `# Fonctionnalités implémentées

+
+export const editorFr = `# Éditeur de carte
+
+L'éditeur de carte est disponible sur "/editor". Il permet d'inspecter et d'ajuster les objets déclarés dans "/public/map.json" directement depuis le navigateur.
+
+## Ce qui est édité
+
+L'éditeur travaille sur la liste de nodes stockée dans "/public/map.json".
+
+Chaque node décrit un objet de la scène :
+
+- "name" : nom du dossier modèle dans "/public/models/{name}/model.gltf"
+- "type" : catégorie de l'objet
+- "position" : "[x, y, z]"
+- "rotation" : "[x, y, z]"
+- "scale" : "[x, y, z]"
+
+Les modèles sont chargés depuis "/public/models". Si un modèle manque, l'éditeur affiche un cube gris de remplacement pour que le node reste sélectionnable et déplaçable.
+
+## Workflow de base
+
+1. Ouvrir "/editor".
+2. Sélectionner un objet dans la vue 3D.
+3. Choisir un mode de transformation : translation, rotation ou scale.
+4. Déplacer la gizmo de transformation.
+5. Utiliser undo ou redo si nécessaire.
+6. Exporter le JSON mis à jour ou le sauvegarder sur le serveur de dev.
+
+## Contrôles
+
+| Action | Input |
+| --- | --- |
+| Sélectionner un objet | Clic sur l'objet |
+| Désélectionner | "Esc" ou clic dans le vide |
+| Mode translation | "T" |
+| Mode rotation | "R" |
+| Mode scale | "S" |
+| Undo | "Ctrl+Z" |
+| Redo | "Ctrl+Y" |
+| Déplacement en vue verrouillée | "WASD", "ZQSD", flèches |
+| Monter / descendre | "Space", "Shift" |
+
+## Actions fichier
+
+### Export JSON
+
+"Export JSON" télécharge la liste actuelle des nodes sous le nom "map.json". À utiliser pour remplacer manuellement "/public/map.json".
+
+### Save to server
+
+"Save to server" est disponible uniquement en développement local. L'action écrit la carte modifiée dans "/public/map.json" via l'endpoint du serveur de dev Vite.
+
+Cette action est masquée dans les builds de production car il n'existe pas encore d'API de persistance production.
+
+## Inspecteur JSON
+
+Le panneau latéral affiche le JSON brut de la carte :
+
+- sans sélection, il affiche toute la liste des nodes
+- avec un objet sélectionné, il met en évidence les lignes du node sélectionné
+
+Utilise-le pour vérifier les valeurs numériques exactes avant export ou sauvegarde.
+
+## Limites actuelles
+
+- L'éditeur modifie uniquement les nodes existants.
+- Il n'y a pas encore d'interface pour créer ou supprimer des objets.
+- La sauvegarde production n'est pas implémentée.
+- Les modèles manquants s'affichent comme cubes de fallback au lieu de bloquer tout l'éditeur.
