An ultra-minimalist dark mode button. By default, it acts as a silent ghost button. On hover, a sharp 1px border glows and the text brightens instantly.
Implement a Vercel-style ghost button for dark mode. The default state is entirely transparent with muted gray text (#888888) and a transparent 1px border. On hover, the text instantly snaps to pure white (#ffffff), the background shifts to a very dark gray (#0a0a0a), and the border illuminates sharply (#333333). Keep transitions lightning fast (150ms ease-out).
