/* ============================================================
   QUICK BOOT REFERENCE
   Shared cheat-sheet styles for the bare ULTR[A] terminal that
   appears on every guide page. Wrapped in <details> on each
   page so it stays collapsed by default.
   Lifted from /guide/container-prefix-universe/page.css (the
   page that introduced the reference) so the rest of the
   guide pages can use the same look without duplication.
