-## Priority 2: 3D System Enhancements (Task #18)
+## Priority 2: Workspace System (Task #77)
+
+**Goal:** Reorganize project into self-contained workspaces to support parallel demo development.
+
+**Design Document:** See `doc/WORKSPACE_SYSTEM.md` for complete architecture.
+
+**Core Concept:** Each demo gets its own workspace directory with timeline, music, assets, and shaders. Common resources shared via `assets/common/`.
+
+**Proposed Structure:**
+```
+/workspaces/
+  /main/          # Main production demo
+    workspace.cfg
+    timeline.seq
+    music.track
+    assets.txt
+    /assets/
+    /shaders/
+  /test/          # Test demo
+    ...
+/assets/common/   # Shared resources
+  /shaders/
+  /audio/
+```
+
+**Benefits:**
+- Clear project organization
+- Parallel development without conflicts
+- Easy workspace switching (`-DDEMO_WORKSPACE=main`)
+- Scales to multiple demos
+
+**Implementation:** 12-16 hours (5 phases)
+
+**Priority:** Medium (workflow improvement)

+## Priority 3: 3D System Enhancements (Task #18)
 
 **Goal:** Establish pipeline for importing complex 3D scenes to replace hardcoded geometry.
