/* =========================================================
   ToolZen Hub
   Time Zone Converter

   Only what the shared tool styles do not already provide: the
   source card, the zone picker (a combobox with a list of
   matches), the converted rows and the meeting section. Buttons,
   focus and headings come from the shared layer. Loaded after
   calculator-responsive.css.

   Day relations ("Same day", "Next day") and every state are
   words, never colour alone. Nothing animates.

   Everything stacks on a phone. From 900px the date, time and
   zone sit in one row. The page itself never scrolls sideways.
