## Description

Ninja-keys is a keyboard-driven command palette and quick-launch menu built as a web component for websites and single-page applications. It functions as a utility for binding, managing, and cleaning up global keyboard shortcuts across different web frameworks and static HTML.

The component integrates fuzzy search indexing to filter available commands dynamically by matching user input strings against keywords and titles across flat and nested structures. It maintains command submenus as a hierarchical state tree that allows users to drill down and bubble back up through parent-child contexts, while listening to document-level keyboard events to capture custom shortcut combinations.

The interface supports custom icons, light and dark color schemes, custom CSS variables, and shadow parts for visual styling and branding. It encapsulates rendering inside an isolated shadow root with adjustable layer depth, and automatically manages component initialization, property updates, and event listener cleanups.
