/* ==================================================================
   GWP ITINERARY READER — styles for the in-page itinerary reader that
   opens from the closing page's VIEW FULL ITINERARY button. Adapted
   from the supplied itinerary package (Honolulu x GWP, Montenegro
   2027), reworked for phones: one slim top bar (Contents, page picker,
   close) and one slim bottom bar (previous, Download PDF, next), with
   the page filling the full screen width. Page-image saving was
   removed for mobile performance; Download PDF is the one action.
   Generic element rules are scoped to the dialog so they can't
   restyle the closing page's button and links.
   ================================================================== */

/* Inter, self-hosted (Latin subset of the package's fonts, SIL OFL —
   see fonts/inter-OFL.txt). Separate family name so these real
   600/700 weights apply only to the closing page and reader, without
   changing how the rest of the site renders Inter. */
