Dark Mode

Dark mode is powered by the next-themes package, which ships bundled as a dependency of nextra-theme-docs rather than something this project had to add separately. A theme toggle supporting light, dark, and system modes appears in the navbar/footer, letting visitors switch explicitly or defer to their OS preference.

No extra application code was needed to wire this up beyond passing themeSwitch labels (for the dark/light/system options) to the <Layout> component in the root layout; theme persistence, the <html> class toggling, and system-preference detection are all handled internally by next-themes and the docs theme.
