# LeftPanel Organism Component

A comprehensive left panel navigation organism that provides a complete layout for filtering and navigation using the AccordionSelectableListContainer.

## Features
- **Organism-Level Component**: Combines multiple molecules for complex UI patterns
- **Clean API**: Minimal props focused on functionality
- **Flexible Styling**: All layout and visual properties via \`style\` prop
- **Responsive Design**: Mobile-first approach with breakpoints
- **Theme Integration**: Uses design tokens for consistent theming
- **Accessibility**: Proper focus states and semantic markup
- **Developer Friendly**: Helpful warnings for missing data

## Usage
\`\`\`jsx
