+# Gym 09 — Scene Switching
+
+Demonstrates switching between a Dialogic timeline scene and a non-Dialogic gameplay scene.
+
+## Flow
+
+```
+gym09_main.tscn          gym09_minigame.tscn
+┌─────────────────┐      ┌──────────────────┐
+│ gym09_intro.dtl │      │ Press button 5x   │

+└─────────────────┘
+```
+
+## How to Run
+
+Open `gym09_main.tscn` in the Godot editor and press **F6** (Run Current Scene).
+
+## Key Mechanic
+
+- `Dialogic.VAR.Gym.minigame_done` acts as a flag between scenes
+- `[signal arg=start_minigame]` triggers `get_tree().change_scene_to_file()`
+- The controller's `_ready()` checks the flag to know which timeline to start

+Miko (neutral): Here's the plan:
+Miko (smile): 1. You're reading this dialog (Dialogic timeline).

+pure minigame — no dialog, no portraits, just gameplay.
