/* =========================================================================
   NOME HELPER WIDGET — styles
   A floating, dependency-free guide that shows the REAL animated NOME mascot
   bottom-right, and opens a panel of page-specific Q&A above it.

   Pair with nome-helper.js. See the comment block in that file for the
   window.NOME_HELP page-config API.

   Theming inherits the NOME Buckets variables from nome-buckets.css when
   present; safe fallbacks are provided so the widget also works standalone.
