+  - `Random` seed button

 ## Generation Behavior
 
 - Rooms are stored as rectangles (`x`, `y`, `width`, `height`) and placed without overlap.
 - Corridors are stored separately as vector line segments between grid cells.
 - Every generated room is connected into one navigable network when possible.
+- A master seed drives deterministic generation, and internal subsystems derive their own sub-seeds from it.
