/* Time-zone calculator (v1.1)
   ---------------------------------------------------------------------------
   Mirrors the Crosswind / Flight planner page rhythm: compact form on top,
   a clear "Calculate" CTA, and result cards below. Designed phone-first
   (single-column on iPhone, two-column once we hit the md breakpoint).

   The iOS bundle layers on top of this with `body.aero-native-ios
   [data-page="timezone"]` overrides in native-ios.css so the result cards
   match the rest of the native shell (deep-navy surfaces, amber accent).

/* v1.1 build 17: standalone neutral eyebrow for the Time-Zone page.
   Previously this element also wore the `.pro-badge` class, which
   prefixed a ★ glyph and shipped an amber pill — making the feature
   read as a premium-only badge. The Time-Zone Calculator is a standard
   tool alongside Crosswind and the Planner, so the eyebrow is now a
   plain blue pill with no star. */
