/* ==========================================================================
   VIPR Guide Design -- components the theme does not style
   --------------------------------------------------------------------------
   Bootstrap 5.3.8 ships fully: nav-tabs, modal, toast, tooltip, accordion,
   spinner, offcanvas and form-range are all in the bundled CSS and JS. The
   theme (main.css) simply never styles them. So these are THEMING gaps, not
   capability gaps -- we use Bootstrap's markup, JS and ARIA wiring and only
   restyle, which keeps the keyboard and screen-reader behaviour we would
   otherwise have to reimplement and get wrong.
   ========================================================================== */

/* main.css hard-codes `grid-template-columns: 1fr 480px 1fr !important` for the

   the navbar keeps a 480px hole in the middle. */
