     - **Effect**: Abstract base for visual elements. Supports `compute` (physics) and `render` (draw) phases. Idempotent `init` for shared asset loading.
     - **Sequence**: Manages a timeline of effects with `start_time` and `end_time`. Handles activation/deactivation and sorting by priority.
     - **MainSequence**: The top-level coordinator. Holds the WebGPU device/queue/surface. Manages multiple overlapping `Sequence` layers (sorted by priority).
+- **Sequence Compiler**: Implemented a C++ tool (`seq_compiler`) that transpiles a textual timeline description (`assets/demo.seq`) into a generated C++ file (`timeline.cc`).
+    - **Workflow**: Allows rapid experimentation with timing, layering, and effect parameters without touching engine code.
+    - **Flexibility**: Supports passing arbitrary constructor arguments from the script directly to C++ classes.
 - **Implementation**:
-    - `src/gpu/gpu.cc`: Simplified to be a thin wrapper initializing and driving `MainSequence`.
+    - `src/gpu/effect.h/cc`: Core logic.
     - `src/gpu/demo_effects.h/cc`: Concrete implementations of `HeptagonEffect` and `ParticlesEffect`.
+    - `src/gpu/gpu.cc`: Simplified to be a thin wrapper initializing and driving `MainSequence`.
 - **Integration**: The main loop now calculates fractional beats and passes them along with `time` and `aspect_ratio` to the rendering system.
