   TIME ZONE CONVERTER — page-specific styles
   Loaded after style.css; reuses its tokens, buttons, fields,
   hero, cards, ad rails and header. No token is redefined here.
   Mirrors the visual language already established by
   /international-meeting-planner/planner.css, kept as its own
   file rather than shared cross-tool CSS, same architecture as
   that page.
