 ## 🏗 Architecture Patterns
 
-These patterns are **mandatory across the entire codebase**. Every class, every 3D object, every manager follows the same conventions. Consistency over cleverness.
+The project uses **two complementary patterns**:
 
-### 1. Singleton Pattern
+- **Singleton service classes** for orchestration and side effects
+- **Declarative React components** for all 3D scene objects
 
-Every Manager and core utility uses the same singleton pattern. One instance, shared everywhere — no prop drilling, no context, no stray `new` calls
+This distinction is intentional. Scene elements such as the map, lights, environment, zones, and player are implemented as **React Three Fiber components** and mounted through `<Canvas>`.  
+Global systems such as gameplay flow, cinematics, audio, and debug tooling are implemented as **manager classes**.
+
+Consistency matters, but the codebase does **not** force the same lifecycle pattern on scene components and global services.
+
+---
+
+### 1. Singleton Pattern for Global Managers Only
+
+Only cross-cutting services use the singleton pattern.
+
+Examples:
+- `GameManager`
+- `CinematicManager`
+- `AudioManager`
+- `ZoneManager`
+- `Debug`
+- `EventEmitter`
+
+These services must exist once, be accessible from anywhere, and coordinate the experience globally.

-Apply the **exact same pattern** to every Manager and utility class (`CinematicManager`, `AudioManager`, `Debug`, `Sizes`, `EventEmitter`)
+**Important:** scene objects such as `Map`, `WorkshopZone`, `Lighting`, or `Environment` are **not** singletons and must remain standard React components.
 
 ---
 
-### 2. Class Interface — `load` / `update` / `destroy`
+### 2. Scene Objects Are React Components, Not Manager Classes
 
-Every 3D class implements the same three-method lifecycle. No exceptions.
+All 3D scene objects are implemented as **declarative React components**.
 
-```ts
+This includes:
-// Enforced interface for all world objects
+- maps
-interface WorldObject {
+- lights
-  load(): Promise<void>         // Load assets, build scene graph
+- environments
-  update(delta: number): void   // Per-frame logic (called from useFrame)
+- player controllers
-  destroy(): void               // Clean GPU memory — mandatory
+- zones
-}
+- interactive props
-```
+- postprocessing layers
 
-```ts
+This keeps the code aligned with the R3F runtime instead of rebuilding a parallel imperative engine.
+
+Example:
+
+```tsx
 // world/zones/WorkshopZone.tsx
-export class WorkshopZone implements WorldObject {
+import { useEffect, useRef } from 'react'
-  private group: THREE.Group = new THREE.Group()
+import * as THREE from 'three'
-  private mixer: THREE.AnimationMixer | null = null
+import { useFrame } from '@react-three/fiber'
+import { useGLTF } from '@react-three/drei'
 
-  async load(): Promise<void> {
+export function WorkshopZone() {
-    const gltf = await loadGLTF('/models/workshop/ebike.glb')
+  const root = useRef<THREE.Group>(null)
-    this.group = gltf.scene
+  const gltf = useGLTF('/models/workshop/ebike.glb')
-    this.mixer = new THREE.AnimationMixer(this.group)
+  const mixer = useRef<THREE.AnimationMixer | null>(null)
-    this.scene.add(this.group)
-  }
 
-  update(delta: number): void {
+  useEffect(() => {
-    this.mixer?.update(delta)
+    mixer.current = new THREE.AnimationMixer(gltf.scene)
-  }
 
-  destroy(): void {
+    return () => {
-    this.mixer?.stopAllAction()
+      mixer.current?.stopAllAction()
-    Dispose.object(this.group)    // ← always traverse before remove
+      mixer.current = null
-    this.scene.remove(this.group)
     }
+  }, [gltf.scene])
+
+  useFrame((_, delta) => {
+    mixer.current?.update(delta)
+  })
+
+  return <primitive ref={root} object={gltf.scene.clone()} />
 }
 ```
 
+Per-frame values such as movement, interpolation, camera smoothing, and physics must stay in:
+- `useRef`
+- `useFrame`
+- Rapier bodies
+- other frame-based systems
+
+They must **never** go through React state.

-### 4. Memory Management — `traverse()` + `dispose()`
+### 4. Side Effects Stay in Specialized Managers
 
-**Every `destroy()` must call `Dispose.object()` before removing anything from the scene.** Skipping this leaks GPU memory (VRAM) silently — no error thrown, just a crash after a few zone transitions. **Rule: traverse first, remove second. Always.**
+Managers other than `GameManager` should not become secondary state stores.
+
+Their role is to manage side effects and specialized runtime logic, such as:
+- GSAP timelines
+- audio playback
+- zone entry detection
+- interaction triggers
+- camera lock/unlock
+- temporary event coordination
+
+They can read from `GameManager`, react to its state, or notify it of important transitions.
+
+Example flow:
+
+```text
+Component / Hook
+      ↓
+GameManager.getInstance()
+      ├── startMission('workshop')
+      ├── cinematic.play('intro_workshop')
+      ├── audio.playAmbience('workshop')
+      └── zone.setActive('workshop')
+```
+
+This keeps the dependency graph understandable while avoiding duplicated durable state.
+
+---
+
+### 5. Memory Management — Dispose Only What You Own
+
+GPU memory must be cleaned carefully.
+
+However, the project does **not** blindly deep-dispose every object on unmount.  
+Only resources explicitly created and owned by the current component or manager should be disposed.
+
+This includes things like:
+- custom materials
+- render targets
+- postprocessing passes
+- manually created geometries
+- manually created textures
+- temporary clones with owned resources
+
+Shared or cached assets must **not** be blindly disposed.
