   terminal.css — the sandbox terminal window.

   Layered on top of styles/site.css, so it inherits the site's cool palette from
   the --term-* custom properties. Nothing here introduces a new colour; if you
   re-tint :root, this follows.

   Class names are namespaced .sandbox* so they cannot collide with the global
   utility bridge in site.css.
