   Two selected themes: dark "Night" (default) and light "Day".

   a stored choice (html[data-theme]) always wins in both directions.
   Display face: Space Grotesk (bundled). Body and UI: the system sans stack,
   which renders as SF Pro for the Apple Silicon audience. Monospace appears
   only inside the console demonstration and small data chips. */
