-**Key behaviors:**
-- `mode = "immediate"` - Element uses immediate-mode lifecycle (recreated each frame, uses StateManager)
-- `mode = "retained"` - Element uses retained-mode lifecycle (persists across frames, uses StateManager for mixed-mode children)
-- `mode = nil` - Element inherits from global mode setting (default behavior)
-- **ID auto-generation** - All elements receive an auto-generated ID if not explicitly provided, enabling state management features
-- Mode does NOT inherit from parent to child - each element independently controls its own lifecycle
-- Common use cases:
-  - Performance-critical static UI in retained mode while using immediate mode globally
-  - Reactive debug overlays in immediate mode within a retained-mode application
-  - Mixed UI where some components are static (menus) and others are dynamic (HUD)
-
-#### Automatic ID Generation
-
-All elements automatically receive a unique ID if not explicitly provided. This enables powerful state management features:
-
-```lua
--- ID is automatically generated based on call site
-local button = FlexLove.new({
-  text = "Click Me",
-  -- id is auto-generated (e.g., "main_L42_child0_123456")
-})
-
--- Or provide a custom ID for explicit control
-local namedButton = FlexLove.new({
-  id = "submit_button",
-  text = "Submit",
-})
-```
-
-**ID Generation Strategy:**
-- **Top-level elements**: ID based on source file and line number (e.g., `main_L42`)
-- **Child elements**: ID based on parent ID + sibling index (e.g., `parent_child0`, `parent_child1`)
-- **Multiple elements at same location**: Automatically numbered (e.g., `main_L42_1`, `main_L42_2`)
-- **Property differentiation**: Similar elements get unique hash suffixes based on their properties
-
-**Benefits of Auto-Generated IDs:**
-- Enables state persistence in immediate mode (scroll position, input text, animations)
-- Allows retained children in immediate parents (mixed-mode trees)
-- Supports state management features without manual ID tracking
-- Stable across frames when element structure is consistent
-
-**When to Use Custom IDs:**
-- When you need to reference elements programmatically
-- For debugging and logging (readable names)
-- When element creation order might change but identity should remain stable
