/* ==========================================================================
   BongaText UI enhancements

   Additive layer on top of the existing Bootstrap 3 admin template. It reuses
   the template's own tokens (brand #5fbeaa, Nunito, #f4f8fb page ground) rather
   than restyling the product, and covers the gaps the review found:
   accessible focus, keyboard skip link, empty / loading states, table and form
   legibility, action hierarchy, and small-screen behaviour.

   Loaded after site.min.css, so plain selectors win on equal specificity.
