Groups render as styled containers with background, border, border radius, box shadow, padding, and animations. All visual element types work as children, and container blocks (conversation, slider, form) can be placed inside groups with video controls. Supports nested groups at any depth.
Conversation blocks now support show/hide toggling while preserving their state (choices, scroll position). ShowHide animations block flow progression, so the flow waits for the longest animation to finish before moving on.
Engine-side hooks for the DOM Inspector dev tool. Console output is forwarded from the engine to the parent frame, and flow state is exposed for step-by-step navigation and execution. Both modules are stripped from production builds.
