Persists a JavaScript object to a browser cookie and mirrors it into React state, handling JSON serialization, initial hydration, and updates when the cookie changes externally. This is the non-obvious plumbing behind the template's dark/light mode persistence. It is a single self-contained hook (React only) that can be dropped into any React or Next.js app for lightweight, backend-free state persistence without external libraries.

Accepts light and dark variants of an image and returns the correct one based on the active color mode, with an internal cache to avoid recomputation. A clean example of decoupling asset selection from the theme context; reusable in any themed React/MUI application for logos and illustrations that need dark/light variants.

The state core of the custom vertical navigation menu: it owns breakpoint detection, collapse/expand state, hover/static toggle behavior, and media-query-driven visibility, exposing them to the menu's styled components via context. It demonstrates how to isolate complex navigation state from presentation so alternative UIs can reuse the same logic. The @menu folder it belongs to is structured as a standalone mini-library rather than being entangled with app pages, making the whole subsystem extractable as-is.

A Node script that generates a single CSS file containing only the icon glyphs the template uses, by reading definitions from installed Iconify packages instead of importing the full icon set. Demonstrates a practical SVG-to-CSS-subset build pattern that keeps admin dashboards lightweight; the script is self-contained and adaptable to other Iconify icon sets.
