/* ==========================================================
   TIME DIFFERENCE CITY HUBS — shared page-specific styles
   Loaded after style.css; reuses its tokens, buttons, fields,
   hero, cards, ad rails and header. No token is redefined here.
   Same architecture as planner.css / tzc.css / ctz.css: a
   dedicated, page-specific stylesheet shared across every city
   hub page (chicago/, and future cities), rather than duplicated
   per city.

   Design principle carried over from the Compare Time Zones
   refinement: compact, information-dense layouts, minimal card
   padding, no excessive vertical whitespace.
