/* =====================================================================
   UI kit (static/js/ui_kit.js): custom dropdowns for every <select>.
   The trigger button copies the select's own classes, so it keeps the
   size and place the select had; these rules add the caret, the open
   state and the rounded menu. Colours come from the Silent Night tokens,
   so both themes work.
