Hello, World!
This is a simple light/dark mode toggle demo.
This is a terminal-style loader component featuring animated typing and deleting text that mimics a command-line interface. It includes a mock terminal window header with colored control buttons (close, minimize, maximize) for a realistic developer environment feel. Ideal for portfolios or developer-themed web interfaces.
