I'll recreate this documentation interface with the three-panel layout, navigation tree, and rich content area as shown in the Figma design.

I've recreated the M.DOC documentation interface with accurate attention to the Figma design. The interface features:

• Left sidebar with the dark blue (#061178) branded header, search functionality, and navigation menu
• Middle panel showing the collapsible document tree structure with proper nesting and folder/file icons
• Main content area with a rich text editor toolbar and formatted document content including code blocks with the dark blue/purple background (#515976), info boxes with light blue background (#d6e4ff), and proper typography

The layout uses the exact colors from your Figma design and maintains the three-column structure with appropriate spacing and borders.
